Batoo JPA is an implementation of Java Persistence API version 1.0 and 2.0. It is created as a response to the assumption that the current JPA implementations are quite heavy implementations that require large CPU resources during execution therefore makes it expensive or impossible to run Java applications on top JPA technology in large scale or mobile and embedded systems. == What is JPA == JPA stands for Java Persistence API a JCP (Java Community Process) Specification led by Oracle and others. JPA allows programmers to map data objects in a java program to database tables and persist, update, remove and query data in object oriented way. Applications developed using JPA are simply need not have to deal with low level SQL statements and transactions making them: * Easy to develop by Junior Programmers with no SQL knowledge, * Disciplined and in integration with supporting and surrounding standards governed technologies, which further standardizes the concepts like transaction management, usage of Enterprise Java Beans, Java Web technologies, etc., * Applications developed on top of JPA are safe to Vendor Lock-in at the levels of implementation of specification (Hibernate, OpenJPA, EclipseLink) itself and database vendor (Oracle, DB2, MySQL, PostgreSQL, Derby, Hypersonic, MSSQL, etc.) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Batoo JPA」の詳細全文を読む スポンサード リンク
