软件简介

JOAFIP (java data object persistence in file ) 使得你可以使用文件系统来保存数据对象，而不是数据库。

主要特点：

• easy to use
• guarantees all ACID properties
• object oriented, write your model, store it. Do not need query language, juste navigate in your model.
• multi data access session ( multi-Thread, transactional data store )
• save all objects of object graph starting from a root object to file system, one heap file record by object instance
• lazy loading of object:
  • make able to not waste memory with large object graph when only need to access to some of them.
  • manage more object than memory can contains
  • about proxy for lazy load
• manage enum state persistence
• crash safe, may accept JVM stop at any time even if write in file ( only the last commit is lost)
• file corruption detection
• garbage collector for file data record that will never be accessed
• The object that can be persited are POJO that not needs to implement Serializable, but there is some conditions
• Possibility to store serialization of instance of class in one data record. can be comprerssed or not
