With the advent of multi-tier architectures, it can be useful to leave the
data in the relational database and also use an object database. The relational
database can then serve as the database of record and continue to support

database to serve the needs of high-performance Internet access. See the example

Customer Review: "Object Oriented Database Design" is a book for beginners and, as far as I have been able to investigate, it is a perfect walkthrough along the background of object structures.
