Exam CISSP Topic 1 Question 304 Discussion

Complex applications involving multimedia, computer aided design, video, graphics, and expert systems are more suited to OODB.
The Object-Oriented Data Bases (OODB) database model stores data as objects.
The OODB objects are a collection of public and private data items and the set of operations that can be executed on the data. Because the data objects contain their own operations, any call to data potentially has the full range of database functions available.
The object-oriented model does not necessarily require a high-level language like SQL, because the functions (or methods) are contained within the objects. An advantage of not having a query language allows the object-oriented DBMS to interact with applications without the language overhead.
Relational models are starting to add object-oriented functions and interfaces, to create an object-relational model.
An object-relational database system is a hybrid system: a relational DBMS that has an object-oriented interface built on top of the original software. This can be accomplished either by a separate interface or by adding additional commands to the current system. The hybrid model allows organizations to maintain their current relational database software and, at the same time, provide an upgrade path for future technologies.
Relational Database Management Model (RDBMS)
The majority of organizations use software based on the relational database management model.
The relational database has become so dominant in database management systems that many people consider it to be the only form of database. (This may create problems when dealing with other table-oriented database systems that do not provide the integrity functions required in a true relational database.) The relational model is based on set theory 8 and predicate logic 9 and provides a high level of abstraction. The use of set theory allows data to be structured in a series of tables that have columns representing the variables and rows that contain specific instances of data. These tables are organized using normal forms. The relational model outlines how programmers should design the
DBMS so that different database systems used by the organization can communicate with each other.
