Legacy Migration
Database Migration
Intelligent Decisions has developed a high performance, minimum risk solution that can transform your legacy database platform to a solid foundation essential for future modernization and expansion.
The IDBridge converts your legacy database and its associated portfolio of application programs to use SQL enabling full functionality with virtually any relational database such as DB2 or Oracle. Since SQL is a generally accepted database language that efficiently integrates with other DBMS or query tools, the IDBridge makes it easy for your new “bridged system” to utilize existing and cost effective, off-the-shelf software and application packages. The IDBridge’s proven, automated tools provide information sharing to data without having significant modifications to the inherent applications.
An easy decision to make!
IDBridge Solutions Highlights
- Uses custom software to migrate data from a legacy DBMS system to a relational database
- Provides enhanced reporting, monitoring and testing
- Allows programs that use legacy databases to access relational databases with little or no change to the current application code
- Utilizes custom-developed SQL I/O module for each legacy file migrated to a relational database
- Supports both batch and online environments
- Leverages DB2 and Oracle and a wide variety of vendor tools that enable monitoring features
- Supports the existing legacy system data structures
- Provides greater performance, functionality and reliability
Code Migration
Systems developed using proprietary mainframe software, fourth generation languages - 4GLs - can be a drain on financial resources. Measures must be taken to reduce costs, increase productivity and provide more control over business operations. To reach these goals, many organizations look to Intelligent Decisions (ID) to transition their 4GL technologies to COBOL.
Our IDMigration solution converts legacy applications written in the major 4G languages to well structured, license free, COBOL CICS systems. After migration, clients can work with their current database code- still intact. Also, with runtime free COBOL programs, CPU upgrades do not incur additional upgrade charges, thus reducing overhead and providing ‘portability’ when needed.
ID’s 4GL to COBOL Migration Benefits:
- Reduction in maintenance and upgrade fees
- Simplification of training / support requirements
- Avoidance of technical ‘version lock- in’ and reliance on proprietary languages
- Minimizes the number of vendors required
- Minimizes audit and change control implications
- No visible changes at the application level
- Functionally identical (where technically possible) to the 4GL
- Potential consumption of large amounts of CPU resources from 4GL’s
- Requirements that most 4GL require their own copy of the program in memory versus sharing of memory and resources
- 4GL’s difficulty integrating with CICS and tracking 4GL program resources
- 4GL’s difficulty providing change controls and audits
