IBM Information Management System (IMS) utilizes a hierarchical database model, distinct from IBM's later relational database model as seen in IBM Db2. In IMS, data is organized into segments, each comprising multiple fields, structured hierarchically to manage complex relationships effectively. [5] For instance, in a customer database, a root ...
Through the integration with the IBM Common SQL Engine, Big SQL was designed to work with all the Db2 family of offerings, as well as with the IBM Integrated Analytics System. Big SQL is a part of the IBM Hybrid Data Management Platform, a comprehensive IBM strategy for flexibility and portability, strong data integration and flexible licensing.

In computing, Open Database Connectivity ( ODBC) is a standard application programming interface (API) for accessing database management systems (DBMS). The designers of ODBC aimed to make it independent of database systems and operating systems. [citation needed] An application written using ODBC can be ported to other platforms, both on the ...
