Teaching Object Oriented Database with Db4o

摘要

Databases are used in many facets of society by an array of people. While the obvious platform for most database applications has been a relational Data Base management Systems (DBMS), the object-oriented programming languages which are widely used in software development are not well matched to their development. In many ways it is obvious that there is an 'object-relational' impedance and mismatch. There are currently only a few courses about object-oriented database development in universities. In this paper, an object-oriented database named db4o is introduced as a viable alternative to traditional database development methods. It is now used in our newly developed object-oriented database course. With a visual object management viewer, db4o helps students to understand basic object-oriented database conception and to grasp programming with the object-oriented programming language.
