ti Object persistance framework updated

What's up?

v2.50 of tiOPF is now available at http://tiopf.sourceforge.net/

So what's tiOPF?

tiOPF is a Object Persistence Framework. That is, it is a framework based around saving your objects to, and loading them from, databases and/or flat files. See the overview for more details.

In a nutshell it lets you do things like:

var
user: TMyuser;
userList: TUserList;
...

user:= Tuser.CreateNew;
user.FirstName:= 'Sean';
user.LastName:= 'cross';

user.Save;

...
userList:= TUserList.Create;
userList.Load;

for user in userList do
...


tiOPF handles the saving and loading of objects to databases and flat files. You can swap between databases by initialising a new persistence layer.


Why should I care?

• tiOPF lets you code in objects rather than datasets (you can still use data aware controls though). This gives you more object orientated code
• tiOPF provides database independance
• Better code reuse. Because the persistance is separated out, you can use the same code across different databases and structures
• Easier unit testing (in my experience anyway). I find it much easier to setup objects and test them that to setup databases and test.
