What is object definition language in DBMS?
Object Definition Language (ODL) is the specification language defining the interface to object types conforming to the ODMG Object Model. Often abbreviated by the acronym ODL. This language’s purpose is to define the structure of an Entity-relationship diagram.
What is ODL and OQL?
ODL = Object Description Language, like CREATE TABLE part of SQL. ◆ OQL = Object Query Language, tries to imitate SQL in an OO framework.

- Select Tools > Code > Instant Generator from the toolbar.
- In the Instant Generator window, select ODL as the Language.
- Fill in the Output Path, which is the directory where you want the code to generate to.
- Select the classes to generate code.
What are ODL classes?
ODL is used to define persistent classes, whose objects are stored permanently in the database. ODL classes look like Entity sets with binary relationships, plus methods. ODL class definitions are part of the extended, OO host language.

What are the parts of the object-oriented programming language standard?
The standard is made up of several parts, including the object model, the object definition language (ODL), the object query language (OQL), and the bindings to object-oriented programming languages. In this section, we describe the ODMG object model and the ODL.
