Given one or more SQL statements, pureQuery provides an intuitive means to auto create the object hierarchies for the relational data access layer. 给定一个或多个SQL语句,通过pureQuery可以直观地为关系数据访问层自动创建对象层次。
Cartographer is a simple, efficient object relational mapper engine. It provides rapid access to relational data using lightweight data and factory java objects. 这是个简单、效的对象-关系映射工具。它使用轻量级数据和工厂对象实现对关系数据的快速访问。
With the object / Relational mapping ( ORM ) of Hibernate framework, the object-based access to Relational database is achieved which separates the developer from the complicated SQL statement. It also highly increases the efficiency of software development, the reusability and the maintainability of the system. 通过Hibernate的对象关系映射(ORM)机制,实现系统对关系数据库的对象化访问,使开发者可以避免直接接触复杂的SQL语句,提高系统的开发效率及系统的可重用性和可维护性。
Hibernate is an open-source framework that carries out the object relational mapping between Java object and data stored in relational database. It can predigest the operation of database access. Hibernate是一个实现对象/关系映射的开源框架,它在Java对象和关系数据库中数据之间建立相应的映射关系,简化了数据库访问操作。
In application based on Java and RDBMS, object / relational mapping can be used to build object persistence layer to simplify Java database access. 在基于Java和关系型数据库的应用中,利用对象/关系映射机制构建对象持久层,可简化Java数据库访问。
