Shifting to Digital Intelligence / Digital Marketing Analytics

According to Forrester research:
Traditional web analytics techniques were not designed for the breadth of channels, devices, and speed that fuels today's digital interactions. It is fundamentally inadequate to accommodate emerging channels, sophisticated consumers, technical challenges, and the democratization of analytics within data-driven enterprises. Because subpar analytics puts customer relationships at risk, Forrester has redefined the modern practice of web analytics as "digital intelligence."
Welcome to the new world, world of Digital Intelligence or Digital Marketing Analytics.

 Analysis of web data can be bucketed into 3 broader categories:

  1. Business Performance Analytics (revenue, margin, biz performance against goals)
  2. Marketing Analytics (user acquisition through SEO/SEM etc.)
  3. Product/Site/Customer Analytics (User behavior Analytics when the user is on the site)
If we are going to compare traditional Web Analytics and Digital Intelligence, we can get this list:


Analytics Types
Web Intelligence Digital Intelligence
Customer/Product Analytics
Mobile App Analytics
Social Media Analytics
Multi-Channel Analytics
Big Data - Hadoop



Organizations in the early stages tend to focus on user acquisition and measuring performance on marketing channels. Organizations extend the analysis efforts from effectiveness of marketing channels to overall impact of business through business performance analytics. As the organization matures, optimization of user experience on the site becomes embedded within the measurement initiatives. Web analytics tools and analysts are primarily focused on marketing analytics and business performance. Product/Site/Customer Analytics is the least served Analytics. Today’s product management teams need better access to data and insights to drive the best user experience on the site. Providing a good site experience is not only helpful in helping the visitors meet the visit goal, but also helps reduce cost as frequency of visit increases. Retained users are known to spend more on the site. User engagement and ultimately higher site conversion helps improve the search Quality Score for the site. Better search Quality Score helps boost SEO rankings and reduced spend for SEM. Google’s search algorithm has Quality Score as a key factor for calculating rankings.

According to amazing book Web Analytics 2.0 of Avinash Kaushik, Web Analytics tools are very good at answering the “What” question. Product/Site/Customer optimization requires answering the “Why” question. Answering the “Why” question needs access to granular data and deep understanding of user behavior at a session level. This data is high in volume and cardinality. The problem is often referred to as “big data” problem. Additionally, with the changing landscape
for mediums that users interact with the site, the importance to have access to granular data in real-time is becoming a requirement.

Some analysis questions are:
  1. Content or article going viral: Organization will strive to have insights into user interaction with the goal to increase visitor stickiness or visit depth.
  2. Understanding marketing campaign effectiveness.
  3. Mobile, social interactions to various content within the online ecosystem.
  4. Optimizing for inventory (physical or virtual) needs access to detail level data in real-time for understanding opportunities to improve the supply chain.

Optimizing the experience in real-time and targeting customers with the right content will help with user experience and improve revenue. Additionally, site uptime is important for revenue and brand protection. Driving Digital Intelligence (DI) for the website is getting ingrained within IT organizations. DI provides all aspects to manage operations for your site. With build in dashboards and reports, all operational elements (page errors, stats by hosts, bot visits etc.) are available in real-time. 


Customers are interacting through multiple channels (web, mobile, social, offline, in-store etc.). Multichannel analysis requires stitching data from multiple data sources. The data is a mix of structured, semi-structured and unstructured formats. Stitching this vast variety of data is not only expensive but also resource intensive. Organizations run multiple month data warehousing projects to stitch the data with limited to no success. Additionally, organizations have to spend enormous amount of resources to maintain these processes. Getting integrated views, with real-time data, are distant realities for the efforts. DI can take and stitch data from multiple formats and create integrated views without the overhead of resource/maintenance cost.


Better analysis needs diving deep into the data, creating segments and doing segmentation on the fly. Traditional web analytics tools have limited segmentation capabilities and options. In most cases, analysts need to predefine segments. Data for these segments is only available after the segments are set. Historical processing of segments is not available. With DI ad-hoc analysis can be done very easily. Segmentation on the fly and ability to do n level segmentation with ability to look at how the segment performed historically is available out of the box.

Finally, there is growing buzz about the term “Data Scientist”. Hillary Mason – Chief Scientist at bit.ly defines data scientist as “a data scientist is someone who can obtain, scrub, explore, model and interpret data, blending hacking, statistics and machine learning.“ In speaking to number of industry leaders, it is clear that data scientist spend an inordinate amount of time and effort obtaining, cleaning, transforming the data and preparing the data for analysis. Part of the problem is the variation in the data (unstructured, semi structured etc.) and part of it is volume. Using data that was gathering from DI sources can be used effectively to help the data scientist shift the focus on creating awesome analysis and searching business insights.

Examples of some questions the DI can answer:

  1. In a business that can take order through site or through customer call center:
  • Call volume has increased suddenly. Is it related to a campaign or is there is a sudden drop in conversion on the site that is driving a higher call volume?
  • Do users calling into the call center spend more than from the site?
  • For every x min reduction in hold time, what is the corresponding increase in conversion and revenue?
  • Do some customers call and use the website at the same time?
  • What is the impact of every dropped call on revenue?
  • What is the impact of every extra 1 min hold time?
     2. How can I create a 360-degree view of the customer who has interacted over multiple channels                  over a specific time period?
     3. Can I get real time visibility into pages or properties within the site that are being used for converted users? Can I get the same for non-converting users?
     4. Are there specific sites trying to scrape content or offers from your site?
     5. Does showing the actual offer change the open rate for email and ultimately the conversion rate?
     6. Can we build out a "what if" analysis for marketing or user attribution for web / telecom / social / mobile?

Upgrade of Production BI Server




It's just a production server, and it's on fire
Hotter than a fantasy, longer like a highway
it's living in a AIX server, and it's on fire
Feeling the catastrophe, but it knows it can fly away 


Oh, it got both feet on the ground
And it's burning it down
Oh, it got it head in the clouds
And it's not backing down

This production server is on fire
This production server is on fire
It's walking on fire
This production server is on fire

Microstrategy Upgrade from 9 to 10

Short path

 The short path is:

1) Delete eisting mucrostrategy software for Test/Dev server
2) Install new version - Microstrategy 10.2 in my example
3) Run configuration wizard, where we should connect existing metadata and than upgrade it
4) Set all settings that was before (Intelligence Server settings, SQL settings, Report layout, LDAP, Memory and other)
5) Run integrity manager (connect upgradet server with old one) and test reports and documents  (sql, data. pdf, excel and etc)
6) Fix the difference
7) Ask business users to work and get feedback
8) Repeat this for Prod

Long path according Upgrade guide:

Upgrade best practices

  • Always upgrade Intelligence Server before upgrading client applications such as Web or Developer
  • Do not downgrade products
  • All products should have the same version

Upgrade process checklist

1 Prepare the MicroStrategy system and projects for upgrade - check prerequisites, back-up the production metadata In addition, it is recommended to duplicate production environment
2 Prepare SDK upgrade
3 Install and configure Intelligence Server 10 and Developer 10 on a test server
4 Update the production metadata
5 Perform basic stability testing
6 Install and configure Intelligence Server in the production environment
7 Install remaining MicroStrategy products in the production environment
8 Test the upgrade and perform other post upgrades tasks

Reviewing upgrade prerequisites

Before install:
  • Installation files
  • License Key
  • Installation location
Recommended installation location and example deployments 
  • Intelligence Server should be installed on its own dedicated server machine.
  • MicroStrategy Web should be installed on its own dedicated Web server machine.
  • The rest of the products can be installed in varying combinations depending on who intends to use them and on what machines.
Prerequisites we can check in MicroStrategy Installation Guide - Planning your Installation

System sizing guidelines

MicroStrategy needs an amount of free disk space equal to at least twice the on-disc size of the metadata database Moreover, due to performance improvements and enhancements, MicroStrategy may require more memory

Upgrading the project metadata

MicroStrategy requires that you update projects through an Intelligence Server connection (3-tier)

High-level steps to configure an upgrade test environment

1 Set up the hardware for the environment
2 Install current version of Microstrategy
3 Via Project Duplication Wizard duplicate production metadata for the test enviroment
4 Check that test IS connect to test metadata
5 Upgrade test enviroment

Upgrade Intelligence Server on Unix or Linux

Install new Intelligence Server and developer on a test server
Uninstall the previous version of Microstrategy, because Microstrategy 10 is not interoperable with pre-10 release
Before uninstalling we should stop IS than start Microstrategy Installation Wizard
After we should reboot machine

Upgrade the drivers for your data source connections

With Microstrategy 10 all drivers are updating. You must manually update Microstrategy configuration files such as odbc.ini and odbc.sh

 Establish a connection to the metadata

After installation we should establish connection between Developer and metadata (details in installation guide)

Update the Metadata

We can check the script  mdRDBMS.sql which update metadata
In order to update Metadata we should use Configuration Wizzard
We should check, that projects are not be locked
For Oracle database we should set Maximum Open Cursors parameter to at least 1500
Only projects that are loaded on Intelligence Server can be upgraded

Metadata Updates using Configuration Wizard

1 Run ./mstrcfgwiz
2 Select upgrade existing environment to Microstrategy 10 and then select IS components
3 Under each IS select systems components:
  • Upgrade metadata repository
  • Lean Objects Migration - new significantly more compact form of object representation in the metadata tables
  • Migrate History List messages
  • Update Distribution Service Objects
4 Select projects from IS
  • Execute project logical upgrade
  • Lean Objects migration
  • update schedules
  • update mdx source objects
  • update olap service cube cashes to PRIME (PRIME architecture can improve the performance of publishing Intelligent Cubes results)
  • Update data import cubes
5 On the Metadata Connection page type the DSN, database login and password to access Microstrategy metadata

Perform basic stability testing on the test server

Check interaction between IS and updated metadata (logging in a project, running a report and create a simple report)

Upgrade and configure Intelligence Server in the production environment

Install Intelligence Server
Install remaining Microstrategy products

Upgrading other Micorstrategy products


Reommended upgrade sequence is as follows:
  1. Intelligence Server and metadata
  2. Microstrategy Web and Mobile Server
  3. Microsoft Office
  4. Developer, Microstrategy Mobile clients, and administrative products such as Enterprise Manager, Command Manager, Object Manager, System Manager, and Operations Manager
After upgrading Microstrategy Web or Mobile Server, Microstrategy recommends restarting web server and clearing cashes
Beginning with version 9 Distribution Services replaced Narrowcast Server as the application that delivers Web delivery subscriptions
We can also migrate subscriptions from within Developer, with the Migrate Subscriptions for Web Deliveries Wizard

Upgrading Enterprise Manager and IS statistics tables

A MicroStrategy Enterprise Manager environment includes the statistics tables, the Enterprise Manager repository, and the Enterprise Manager project metadata. Each part of this environment needs to be upgraded.
The statistics tables and Enterprise Manager repository can be upgraded at the same time, using one of the approaches below:
  • Completed Upgrade
  • Phased Upgrade

Complete upgrade of Enterprise Manager statistics and repository

In a complete upgrade, you upgrade all Intelligence Servers, all projects, and Enterprise Manager to the latest version simultaneously. This is the simplest method of upgrading your MicroStrategy environment.
  1. Close all user connections, to ensure that no session activity exists on the Intelligence Servers being monitored by Enterprise Manager.
  2. Using Operations Manager, run an Enterprise Manager data load. Make sure the Close orphan sessions option is selected. This data load ensures that the statistics tables are completely up to date and that all open Intelligence Server sessions are closed. If you do not run a data load before upgrading Enterprise Manager and the projects on the Intelligence Servers, you may lose access to some statistics data.
  3. Upgrade all the Intelligence Servers that are being monitored by Enterprise Manager to the latest version through Configuration Wizard.
  4. Update all projects on those Intelligence Servers to the latest version through Configuration Wizard.
  5. Shut down all Intelligence Servers that are being monitored by Enterprise Manager.
  6. Upgrade Enterprise Manager to the latest version.
  7. Create a backup of the statistics tables and the Enterprise Manager repository. These should be stored in the same database.
  8. Upgrade the statistics tables and Enterprise Manager repository
  9. Restart IS
  10. Using Operational Manager run an Enterprise Manager load
  11. Upgrade the Enterprise Manager project

Updating the Enterprise Manager Project

MicroStrategy 10 includes major enhancements and updates to the Enterprise Manager project. As a result, older versions of Enterprise Manager projects cannot be used with MicroStrategy 10. However, when upgrading your Enterprise Manager project, your customized Enterprise Manager reports or other objects may be retained.
  1. Use the Project Duplication Wizard to make a backup of your existing Enterprise Manager project. For detailed information about using Project Duplication, see the Managing Your Projects chapter of the MicroStrategy System Administration Guide
  2. From the Start menu, point to All Programs, then MicroStrategy Tools, then select Configuration Wizard. The Configuration Wizard opens.
  3. Select Upgrade existing environment to MicroStrategy 10, and click Next.
  4. Select Upgrade Enterprise Manager Project, and click Next. The Enterprise Manager Project Upgrade page opens.
  5. Provide the following information:
    •   User Name: Type the MicroStrategy user name that can access and administer the Enterprise Manager project.
    •   Password: Type the password for the MicroStrategy user that can access and administer the Enterprise Manager project.
       6. If you have an Enterprise Manager project package file (.mmp) to use instead of the default file, click Advanced >>. For the Package location field, click ... (the Browse button) to navigate to and select the package file.

Testing the Upgrade

Functional testing

Functional testing verifies that functionality from the previous MicroStrategy version remains the same or improves after an upgrade to a new version. This includes various administrative tasks, as well as viewing, manipulating, and designing reports and documents.

Administrative testing

The best way is to run Integrity Manager and compare reports and etc.

End user testing

End users are the best source of day-to-day use cases for your MicroStrategy system. Because they are able to create accurate real-world testing conditions, end users must dedicate time to executing their test cases and report any unexpected behaviors. The functional end user testing period may encompass a few days or several weeks, depending on the size of your MicroStrategy system.

Integrity testing

After upgrading your system, you should ensure that the changes involved do not alter any of your report results. MicroStrategy Integrity Manager is designed to execute reports and documents from a project, note whether or not they execute, view their results, and compare them against reports and documents from another project.

Best practices for integrity testing

MicroStrategy recommends the following best practices when testing your upgrade with Integrity Manager:
  • Create an integrity test comparing reports from the upgraded test environment with the same reports in the production environment, so that you can easily see where any differences are.
  • Execute the tests against the production data warehouse. If this is not possible, test against a data warehouse that resembles the production data warehouse as closely as possible.
  • Execute the tests under production users, groups, and security roles, instead of specially-created integrity test users and groups, so that the tests match the production environment as closely as possible.
  • Use prompt answers that are used in the production environment.
  • If you are upgrading from MicroStrategy 9.0 or later, use default personal prompt answers for prompts.

Performance testing

Performance testing verifies that the response time, resource usage, and throughput in your environment meet the expectations of your end users. In the context of an upgrade scenario, the goal of performance testing is to verify that the system’s performance is maintained or improved by the upgrade.
During a performance test, you should ensure that memory and CPU usage are within acceptable ranges.
There are three different kinds of performance tests:
  • Load tests verify that the system is stable under normal usage conditions.
  • Stress tests verify that the system is stable under high usage conditions.
  • Capacity tests help determine the maximum workload the system can support while still meeting performance expectations.
 

Integrity Manager

You can use Integrity Manager to automate your performance testing. Integrity Manager can record how long it takes to execute a report or document. It can also execute the reports or documents multiple times in the same test and record the time for each execution cycle to give you a better idea of the average Intelligence Server performance time.
A single instance of Integrity Manager can execute a performance test that duplicates the effect of a user running multiple reports. This is suitable for load testing. If you are performing stress testing or capacity testing, you may need to distribute the load among multiple user sessions. To do this, you must run several instances of Integrity Manager, each executing a performance test.

Resolving problems encountered during the upgrade

  • Make sure you have met the system requirements and other prerequisites for the current version of MicroStrategy, as noted in Reviewing upgrade prerequisites, page 11.
  • Be aware of the level of interoperability between the current version of MicroStrategy and the version you are upgrading from, as noted in Client/server interoperability, page 2.
  • Any errors in the upgrade process are likely to be written to the installation log file, install.log. This file is in the directory that you specify as the installation directory during the upgrade.
  • When you use the Configuration Wizard to add tables to the metadata or update your projects, each SQL statement that is executed is logged to the Configuration Wizard log file, MACfgWiz.xml. This log file is in the Log subfolder of the main MicroStrategy directory. You can analyze the log file using a third-party log viewer, such as the Apache Chainsaw log viewer, which can be downloaded from http://logging.apache.org/chainsaw/index.html.
  • If MicroStrategy Web users encounter errors after you upgrade MicroStrategy Web, you may need to clear your application and web server caches, or your users may need to clear their browser caches. For instructions on how to clear these caches, see the documentation for your web server, application server, and web browser.
  • MicroStrategy recommends upgrading to the latest version without uninstalling the previous version of MicroStrategy. However, in rare situations, issues may be encountered as a result of an in-place upgrade.

After the Upgrade

Checking and assigning privileges

It is essential you take the time to assign and make changes to the many user permissions that affect your MicroStrategy system. Review the following for a list of privileges you should manually assign to users after upgrading MicroStrategy.
To access the Find and Replace Privileges dialog box
  • In Developer, log in to a project source as an administrator.
  • From the Administration menu, point to User Management, and select Find and Replace Privileges. The Find and Replace Privileges dialog box opens

Completing the upgrade process

Once the upgrade process is complete, you should tune and optimize your MicroStrategy system for performance and stability reasons. For information about administering, maintaining, and optimizing your MicroStrategy system and projects, see the Tuning chapter of the MicroStrategy System Administration Guide.

CA Erwin Upgrate from r8 to r9

Background:

Our company currently uses Erwin Datamodeler Workgroup edition with Mart r8. This release doesn't support Oracle 12C. As a result, we are going to upgrade r8 to r9. Below you can find information about r8 and r9 architecture and action plan of installation r9 and upgrading of mart.

Introduction:

CA ERwin Data Modeler Workgroup Edition provides a multiuser modeling environment that makes coordinated, large-scale modeling possible. It enables collaboration among project managers, data modeling team members, and standards administrators by providing workgroup modeling services, including conflict resolution, versioning, security, and standards management. You can coordinate the efforts of model teams to document existing systems, create new eBusiness systems, and drive data standardization. Model sharing encourages teamwork, so modelers can work together more efficiently to optimize model-based development. Your modelers get more work done in less time with better results.
Earlier, when you upgraded to a new version of CA ERwin DM, only the schema was upgraded. To upgrade your models, you opened each model in the new version. This process took much of your time, especially when you had to upgrade large models. In CA ERwin DM Version 9.0, upgrading models is automated through the Mart Upgrade utility. The utility lets you upgrade not just models, but users, profiles, and permissions too. In addition, the utility also lets you upgrade to a different database.
New features:
  • In release 9 we can migrate users, profiles and permissions
  • New MartUpgrate utility automatically migrates your models and the other data
  • We can selectively migrate models
  • We can pause upgrade and start it later
  • The MartUpgrade utility available with CA Erwin Data Modeler Workgroup Edition r9 Installation
  • MartUpgrade Utility does not install with the Mart Server, it installs with Data Modeler Workgroup Edition
  • You must enable that option during installation

Mart Architecture

In order to upgrade Mart we should install Mart 9, because it has new architecture. There are 2 pictures of current architecture and architecture of new mart:

Erwin r8 architecture:

Erwin r9 architecture:



The new architecture has the following benefits:
  • Separate logical and physical users: In the previous versions, Mart (or Model Manager) users required database level privileges to access Mart functionality. The Mart database administrators added or deleted users in the Mart database. This approach is changed now. The logical users are separated from physical users, so Mart Administrators can create Mart users without creating the corresponding database users.
  • Authentication through Active Directory services: Earlier, if you wanted to provide access to a user group, you added each user individually. Now, because of the new architecture, you can use the Active Directory services and can provide access to the group. Anyone who is part of the group gets access.
  • Mart administration outside CA ERwin Data Modeler: In the previous versions, Mart Administrators used CA ERwin Data Modeler for administrative activities such as permissions management. This required non-modelers to know how to use CA ERwin Data Modeler. In the new architecture, the administration component (CA ERwin Web Admin) is built on a separate layer on top of CA ERwin Data Modeler and is hosted on a Web server. Mart Administrators can access CA ERwin Web Admin from any computer and can perform administrative activities through a web console.

Installation and Configuration of Mart r9

Mart comprises the following components:
  • Database (Oracle)
  • Applications
  • Web server (Tomcat or IIS)

Check license on clients machine:


Standalone model

The upgrade r8 to r9 is direct
Open the *Erwin file using File|Open and upgrade it within r8 CA Erwin DM

MART upgrade

The Upgrade Mart utility lets you upgrade models in several ways. You can choose the best way that helps you get started with your work quickly. Upgrade models in one of the following ways:
  • Upgrade the top ‘n’ versions.
  • Upgrade only the marked versions.
  • Upgrade all marked versions and top 'n' versions.
  • Upgrade all the versions of all the models.
Regardless of the option you select, you can start working on a model after the model is upgraded. You do not need to wait until all the models are upgraded.
The Upgrade Mart utility lets you pause the process any time and start again. When you pause, the utility completes upgrading the current model before stopping. When you restart the upgrade process, the utility continues from the point it had stopped. The utility then displays the models that are not yet upgraded in the list of models that you had selected.
The following diagram illustrates how you upgrade models:


CA Erwin macros

CA Erwin offers us list of macros which can make our life easy. Let's meet them:

%AttName - attribute name
%AttDomain - logical domain name
%ColName - column name
%ColDomain - physical domain name
%EntityName - entity name of the current entity
%EntityProp (UDP Name) entity UDP value of the same name specified
%Lower - puts the object name in lower case
%OwnerEntity - name of the entity that ownes the current attribute
%TableProp (UDP Name) table UDP value of the name specifified
%TableName - table name
%Upper - puts the object name in upper case

Let's look on particular example. For example, we can create new domain Last Name. It could be Student Last Name, Employer Last Name or etc.

The advantage of domain that we can reuse one object many times. It is simply saves time and increases productivity and quality of data models.



We just use macro: %Lower (%OwnerEntity %AttDomain)

Microstrategy Web - apply setting for all users

Recently, I got one request from user, that she wanted see 12 columns per page and she saw only 10. However, my user saw all 12. In order to fix it we should change prefernces - grid display. If we want to change it for all users, then we need login as administrator and then go to preferences. In preference level choose Projects Defauls. Now we can set properties for all users.
