Sender: Jewelry (Wolf Eat Radish), News District: Java Title: JDO Resource Introduction (ZZ) Send Station: Sun and Moonlight (May 08, 2003 18:21:13 Thursday), station letter
I mainly study questions about JDO. First introduce the background: JDO Since 1999, it has submitted an outline from some experienced developers who often write database object mappings. They have a large number of database-oriented development and objective packaging. , Finally, a variety of packaging methods have caused many compatibility issues. So some major development groups jointly, with Sun as leading sheep, developed JDO specifications. It is not to replace JDBC or EJB, but on the basis of JDBC, it can do the bottom of EJB. JDO is mainly for small and medium-sized projects, but with more and more Features, such as distributed synchronous controls, JDO is increasing. . JDO Specifications Under the leadership of Sun's experienced Craig Russel, after three years of discussion, the first edition finally formed in April 2002. The latest version is version 1.0.1, can be seen in http://access1.sun.com/jdo/. (Everyone should know that Java's standardization time is generally a long, because it is too open, anyone can express opinions, participants must consider)
