# 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.

1. 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.

1. 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](https://github.com/lightweight-component/dataservice-ui).

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

- Map

- Java Bean

Currently supported databases (with more to come):

- MySQL

- SQLite

- Derby
