Re-born of old technologies with new technologies
Data base integration technologies are fast evolving. In a way they are giving extended life to the legacy applications with powerful integrations to the new generation applications. What are they and how are they being used?
The objective of adoption of new generation ERP applications (Oracle, SAP, Siebel etc.,) is to provide the efficient system for the businesses to operate with state of the art of technology. In parallel there other technologies that are developing which are capable of real time integration of the so called legacy applications with the new generation applications. This typically requires integration if heterogeneous data systems. This is in a way extending the life of legacy systems. Use of these technologies makes more sense for the business now a day to control the Initial investment costs of Business systems and more importantly manage the change effectively as the legacy systems will continue to exist.
Let us look at the various technologies that are evolving and
1. OBIEE - An acronym for Oracle business Intelligence enterprise edition aims to have the data from any database system to integrate the data with Oracle EBS (Enterprise business suite) and generate powerful reports. All that is required is to build an integration layer for the data transfer and configure the seeded reports.
2. Streaming - Streaming is a streamlined process to capture the changes in the database, load them to a staging table and consume. The staged data can be used for downward integration and continue the existing reporting systems. This is a kind of Push system where the source system needs to push the data to the staging tables.
3. The other advancement is to make the destination system (let us say SQL server) to pull the data from the Oracle EBS or other ERP system. Appropriate materialized views can be created on the source system and the data base links are to be created between the systems. The destination system will keep pulling the transactional data from the source and the same can be used for reporting or queries etc., this eventually reduces the load on the transactional system.
All these advances help the business to retain the existing systems instead of fading out and still get the important business benefits.
There may be new technologies as well in this arena.
