Does OODBMS Offer a Solution?
Object-Oriented Database Management Systems (OODBMSs) emerged upon the scene in the 1990s, after object orientation had become the name of the game. Object-oriented database management systems are good for manipulating data since they store it in object form, preserving the relationships between the objects. An OODBMS works under the assumption that databases should store data objects that map directly to the objects defined in the programming language used for writing the application. These systems are based on object models that preserve the hierarchical relationships between objects, retain rich data types and offer a more sophisticated translation from objects to stored data. Figure 2 illustrates the role that object-oriented databases play in object persistence. However, the bottom line is that data stores for back-office systems are RDBMSs. So a mapping from object to relational and vice versa needs to be created in order to offer persistence capabilities via OODBMSs. The only wa
