This is a Data Access Object implementation for Java, coupled with the Data Transfer Object which i use in my Java projects and it makes my job easier as i dont have to write insert/update/select/delete basic queries by Hand for every table in my database.

DTO serves as the Base class, Each DTO extended class must have a 
String tablename : name of the table which this DTO represents
Arrayist<String> columns : list of columns in the table, first column being the Primary Key always.
Arrayist<String> columns = new ArrayList<String>(Arrays.asList("id", "name"));

1. Method Implemented:
2. insert(T dto)
3. insertMany(ArrayList<t> dtos)
4. selectById(T dto, String id)
5. selectById(T dto)
6. selectAll(T dto)
7. selectWhere(T dto, List<String> columns, List<String> where)
8. selectWhere(T dto, String whereColumn)
9. selectWhere(T dto, List<String> where)
10. selectWhere(T dto, String selectColumn, String whereColumn)
11. selectWhere(T dto, List<String> select, String whereColumn)
12. deleteById(T dto)
13. deleteWhere(T dto, List<String> columnsWhere)
14. updateById(T dto, List<String> columnsToUpdate)
