Overview
Dado is a package that offers some facilities implemented over LuaSQL connection objects. Its main goals are:
- better error messages,
- iterators to access the result set and
- more homogeneity in some commonly used database operations.
Dado is free software and uses the same license as Lua 5.1.
Object Abstraction
The package also contains an object module which provides a way to define classes and objects to represent table rows with a minimun effort. It does not imposes a class system, it just suggests a simple one with simple inheritance:
- objects with automatic retrieval of database attributes
- different methods for object creation and for class definition
The default mechanism uses classes to represent database tables and instances to represent database table rows. However it is easy to define attributes that are not related to database columns, or classes that are not related to only one database table.
