JDO resource introduces I mainly study JDO problems. First introduce the background: JDO Since 1999, it has made an outline from some experienced developers who often write database object mappings. They have conducted a lot of database processing and objective packaging in the long-term object-oriented development, and finally Many diverse packaging methods have caused many compatibility aspects. So some major development teams 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 primarily for small and medium-sized projects, but as the product provider gives more and more functions, such as distributed synchronous control, JDO's role is growing. JDO specification under the leadership of Sun's experienced Craig Russel, after three years of discussion, finally formed a first edition 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 longer, because it is too open, anyone can express opinions, participants must consider) the currently doing better manufacturers (Vendor): Kodojdo http: //www.solarmetric.com, mainly focus on performance and distributed synchronization JDogenie http://www.hemtech.co.za/jdo/index.html, mainly paying ease of use, easy to learn, configure a free product: Tjdo http:// http://sourceforge.net/projects/tjdo/, based on Sun's Reference IMPLEMENTATION, add some extended JDO resource network: http://www.jdocentral.com/ More mature discussion area: http : //www.jdocentral.com/forums/index.php a few more active character: http: //www.jdocentral.com/forums/index.php s = 877f580c72fa2287d4a4bfe57d50e67d & act = Members & max_results = 10 & sort_key = posts & sort_order = desc where?
