Lightweight Data Access Object in Java

AJ-Data boosts the CRUD development, not just an ORM library. There's three layers in this architecture:

1. JDBC Connection, JDBC reader and writer, is like Spring JDBCTemplate or Apache Dbutils. It accepts SQL String and Map params then outputs a value, or a Map, or a Java Bean, or a List.
2. CRUD Service, is a layer on top of the first layer, also the extender: FastCRUD provides the Common Implementation for rapidly CRUD operations without a lot of coding, plus a simple REST API is readily available.
3. DataService, is a layer on top of the second layer, to write your own SQL or logic on the Web page, then REST API is prepared. More Info pls check out here.

We support two primary data formats for both input and output parameters:

• Map<String, Object>
• Java Bean

Currently supported databases (with more to come):

• MySQL
• SQLite
• Derby
