Lightweight codeigniter/php cms that easily plugs into site code

I have another codeigniter CMS suggestion question. Pretty much I am just looking for a CMS that allows my client to easily add in content that doesn't necessarily need to be tied into a page. I pretty much want a MYSQL database with a gui that allows the client to upload content to certain tables in the db. I don'开发者_如何学Ct want any themes attached to the cms as the site code will all be custom built and I would prefer to write all the db calls to pull data for specific pages. I just need a way for the client to easily upload data to a table where I can create a model to pull the data.

I have heard of FuelCMS, Ionize, and PyroCMS but all these seem like they have too much. I am looking for a pretty barebones db that has a gui and good documentation for the api's. That's all.

Thanks!

I know you wouldn't think of ExpressionEngine as "lightweight" but from the perspective that you are speaking, it is...

It allows complete control of content separate from any design's or concepts of "pages". It's power is that you define "objects" or channels that contain specific information that you then take and construct the pages around. Channels are a more user friendly concept of the MYSQL tables you're talking about.

DownsideYou get good support because it's not free, but and worth the money.

It's module development pattern is familiar if you are a codeigniter developer also.
