[ODB1] Chapter 2 - A Quick Tour

This chapter introduces basic ObjectDB and JDO concepts, using two sample programs. We start with the HelloWorld sample program, which is not JDO portable because it uses some ObjectDB extensions, but it is a good sample to start with because of its simplicity. We then proceed with the JDO Person

Getting Started

ObjectDB is very easy to use. Follow the Getting Started Tutorial and the Quick Tour manual chapter and in minutes you may be able to write and run first Java programs against ObjectDB.

Prior knowledge or experience in database programming (SQL, JDBC, ORM, JPA, etc.) is not required, but some background in using the Java language is essential.
