what is object oriented database management system pdf

The issue is not the relative merits of one programming interface versus another, but rather the processing model inherent to the interface and its relation to the database structure itself. Of more significance for this discussion, all databases provide some sort of programming interface to the data they manage. Object-oriented databases treat each entity as a distinct object. These utilities differ from vendor to vendor and from platform to platform, but they all serve the same purposes in all database management systems. Object-oriented databases, then, are an attempt to solve the problems mentioned (as well as others) and still maintain the advantages of database systems. Database management systems typically include utilities to maintain backup copies of data, to control simultaneous access and updates of data, to build input forms, and to construct views and reports of data. The other pieces of the database system exist to provide controlled access to and use of the data in the system. The data is only one piece of the database system. However, this picture ignores the role that processing plays in the structure and use of the data in the repository. Its goal is to determine whether object-oriented modeling can be transformed from an abstract design tool.

For a relational database in particular, this is not that bad a picture of the data repositories managed by the database system. Database management systems typically include utilities to maintain backup copies of data, to control simultaneous access and updates of data, to build input forms, and to construct views and reports of data. Sembase is a database management system based on an object-oriented, or semantic, model. For most people, the word database conjures up a vague picture of a large file of data arranged something like a ghostly spreadsheet.
