Using object types and objects v15

You can use object-oriented programming techniques in SPL. Object-oriented programming as seen in programming languages such as Java and C++ centers on the concept of objects. An object represents a real-world entity such as a person, place, or thing. The generic description or definition of a particular object such as a person, for example, is called an object type. Specific people, such as “Joe” or “Sally”, are said to be objects of object type person. They're also known as instances of the object type person or, simply, person objects.

You can create objects and object types in SPL.

  • The terms “database objects” and “objects” are different from the terms "object type" and "object" used in object-oriented programming. Database objects are the entities that can be created in a database, such as tables, views, indexes, and users. In the context of object-oriented program, object type and object refer to specific data structures supported by the SPL programming language to implement object-oriented concepts.

  • In Oracle, the term abstract data type (ADT) describes object types in PL/SQL. The SPL implementation of object types is intended to be compatible with Oracle abstract data types.

  • EDB Postgres Advanced Server hasn't yet implemented support for some features of object-oriented programming languages.
