| 摘要 |
The present invention uses annotations and SQL to retrieve and/or persist POJO data from/to a database, respectively. Using SQL will enable developers to unleash the full querying power of their chosen Database Management Systems (DBMS) and will remove the requirement that they learn a new query language. A minimal amount of annotations will be associated in the same Java(R) source file where each class of POJO to be persisted to the database is defined. An enhanced compiler is capable of analyzing the annotated source file and automatically generate the bytecode required to create, deploy, and manage the persistence of POJOs without requiring knowledge of specific details of the persistence to corresponding data entities in the underlining database. Therefore, such an approach decreases the time, knowledge, skill and ultimately cost required to persist POJOs to an underlying database. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
