Rather than continuing to design their enterprise software to run on databases built by other companies, SAP SE created their own innovative database, designed to move customers toward a faster, more flexible all-SAP landscape. Its central feature is an innovative, column-based Relational Database Management System RDBMSwhich is used to store, retrieve and process data on core business activities. As such, companies have to make choices about what software best meets their current needs. Most databases store the majority of their information on disk, and can only keep a limited amount of information in main memory; disk is relatively slow, which limits how fast the application can recall information.
In this part we're going to talk about how important it is to know where you are starting from, before you head off on a new application journey.
Understanding and mapping your legacy systems is a key success factor for a data migration project, but can be a very difficult and time consuming battle.
In this post, I'll talk a bit about some approaches I've found useful in my experience. If you like, you can start with Part one which was a light hearted introduction to data migration projects in general, and part twowhere we talked about the importance of data quality.
Why are we spending so much time on this?
Thats the OLD system- we need to focus on the future! Here are just some of the important things the legacy mapping needs to clarify: Data location- You can't migrate data if if you don't know what it is and where it is. Data dependencies to other systems All processes and interfaces that rely on interfaces to the legacy systems need to be either replaced or shut off.
Often this means that even if the new system is not involved, other systems may stop working because they get data from the legacy systems. The data migration project is not just about turning on the new system.
The consequences of turning off the old system have to be known and managed. Legal requirements to keep legacy data available. Even if data is not migrated to the new system there may be additional data migration requirements into data warehouses or documents that have nothing to do with the new application.
The actual infrastructure that the legacy systems are on might perform other tasks that although not directly related to the legacy system will cause issues when that infrastructure is removed.
For example, someone installed a service of some sort on one of the servers that is used by other applications that are completely unlrelated from a data point of view.
Often the first time the Legacy system is documented is just before it's shut down. Despite our best intentions, sometimes documentation doesn't get updated. This is the reality for many systems, and particularly for legacy systems.
One of the first steps in a data migration project is to gather all the existing documentation for the legacy systems, and all the systems they talk to, and make sure its accessible to the data migration project team. It is critical to have tight control over these documents, and to ensure that everyone works off a "live" version- because your mapping is going to update that documentation, and every developer, data modeler and application team member needs to know that they have the best and latest version.
The application interface diagram. Now, the ideal situation is to have a dynamic, self correcting, scanning Configuration Management Database tool CMDB tool that already has every scrap of meta data about every application and all its interfaces ready to go.
If you have one of these, good for you, and you can stop reading. For the rest of us, lets talk practical methods of mapping what we have.
How to get the data. Scan the environment- catch the interfaces in the act. Monitor network traffic to detect exchanges between applications. Scan file systems to find interface files and determine frequency. Catalog services and activity of those services on servers.
Get out there and talk to people. Ask people- where is data from this system used? Look at management reports and trace backwards to find where information is pulled.In the new era of digital transformation, new strategies and technologies are taking over the legacy applications to run the day to day business.
As a result of new technologies driving in, when new digital next generation aligned applications are deployed to production, many of the mainframe legacy.
