Final answer:

The object-oriented model in database design stores data and methods together in objects, representing data in a hierarchical manner instead of two-dimensional tables. The model was not first developed by Charles Bachman. Objects in the model are connected using references or pointers.

Step-by-step explanation:

Object-Oriented Model in Database

The object-oriented model in database design is a data model that represents entities as objects and their relationships as associations. It combines data and methods into objects, which are stored in the database. Unlike the relational model that uses two-dimensional tables to store data, the object-oriented model represents data in a more hierarchical manner.

False: The object-oriented model was not first developed by Charles Bachman. It was primarily influenced by the work of Simula and Smalltalk programming languages.

True: Data and methods are stored together in the database, encapsulated within objects.

False: Data is not presented as two-dimensional tables in the object-oriented model. Instead, it is represented in more complex structures, such as hierarchies or networks.

False: Records in the object-oriented model are not connected using common data items. Instead, objects are connected using references or pointers.
