Hierarchical HDBMS or network NDBMS to relational RDBMS migration

Issues:

Your information systems are still sometimes based on hierarchical HDBMS or network NDBMS like DL1, IDMS, IDS2, or pseudo-relational like DATACOM …

For reasons of maintenance, support, interoperability, availability of competent resources or simply costs, it becomes necessary to migrate to a standard relational RDBMS.

 

Moving from a hierarchical or network DBMS to a relational DBMS asks a number of questions:

  • The kinematics of the programs, based on a particular data organization must be modified, while maintaining the performance level,
  • Queries, often very numerous in an application heritage must be rewritten,
  • The data must be transferred to the new DBMS respecting the typing constraints and possibly the EBCDIC to ASCII conversion
  • Identical functioning of the system after migration must be checked

Our Offer:

The project approach is summarized below. It begins with a study and prototyping phase before moving on to an industrial phase once the key points have been dealt with.
