In an ORD, a traditional database is used to store the data. Thus, different tables are related to one another with the help of different key fields. A database is a set of data stored somewhere, organized in a schema (we’ll discuss this in more detail later on). Other Database Stuff - Database Design. Each table requires a unique key that is used to connect one table to another. The DBMS accepts the request for data from an application and instructs the operating system to provide the specific data. A relational database allows the definition of data structures, storage and retrieval operations and integrity constraints.
