Final answer:
ODL and OQL are used in the ODMG Standard for class declarations and object manipulation in databases, providing standardized definitions and interactions in database environments.
Step-by-step explanation:
For class declarations that deal with database concepts in binding in the ODMG Standard, the Object Definition Language (ODL) and the Object Query Language (OQL) are used. ODL is used for defining the data types, classes, and relationships between the classes in a database, whereas OQL is employed to manipulate objects within an ODMG-compliant database. These tools provide a standardized way to define and interact with objects in a database environment, ensuring consistency and facilitating clearer communication between different systems and developers.
