For a current project involving large amounts of unstructured and structured data, I needed a Key/Value style DB.

So after looking around at the current options nothing really suited my needs (.NET based, relatively small footprint, simple as pie) I decided to write one, it is [imaginatively] titled ItemDB and is sort of modeled after the way freebase store’s its data and my own views.

With ItemDB (currently in early stages of development) there are three main concepts to think about; Item, Fact, Relationship.

An Item is the main storage item in ItemDB (as an example let’s create an Item called Josh), with ItemDB this is the main thing we need to worry about.

A Fact is a bit of knowledge about the Item that its contained in (let’s add a Fact to the Item we created previously called age, we will set it to 21), Facts generally live in a FactCollection witch is the subject of a later post

A Relationship is well, a relationship between one fact and another (let’s add a relationship between Josh and Coke with a relationship type as FavoriteCaffineatedBeverage)

These three concepts should allow for incredibly complex capability

This would usually be the bit with a link to the current build of ItemDB or something along those line, but there is a problem with that, It’s not quite ready for its public showing (current lack of  persistence being a large part of that). Stay tuned

As per usual, Any questions leave a comment.
