SDK is not for editing database files. SDK is a development kit, which we used to create the models, levels, effects for the game.
If you want to unpack the database files, you should look for a database unpacker tool. Since we never wanted to unpack what we packed (for what), we never made unpackers, but they are available since 2007 in the modding communities.
A simple one:

Why we packed the configs and scripts? I will be honest, Every game ships with a clean install, and you can not imagine how many mails were sent to us about the unpacked gamedata. What to do with it? why is it there? and so on. People kept on editing files randomly, which sometimes crashed the game, and we got the black soup, and requested us to fix the bugs generated by their lack of knowledge in changing files. Since LA was/is an early access game, we had more than enough trouble to fix the real bugs, which werent caused by edited files, or installed mods over the original game. Everything started to slip out of our control, so we decided to pack the files, and create a clean game with the 2nd patch. The second reason was to help modders and reduce the "fuuuu" effect of players, who installed mods on LA, and when they wanted to remove or change the mod, they had to reinstall the game (unless -1 to 5% of them thought about that- they made a backup of the gamedata dir before they started to install stuff over it). Now only modders edit the files, and if they release a mod for LA which contains gamedata dir, it will be easy to install or remove, their files wont get mixed up with the retail LA files.
