In order to do some custom database work, I did a relations engine (don't know what else to call it, but I think it's a stupid name), that'll help making relations between words and values.

So what's wrong with this?

This is fine if you don't need anything more than this, but the fine part about this engine is that it works on a tree structure and you can have an infinite amount of levels of one-to-one and/or one-to-many relations.

Example:

You can relate a customer to a specific invoice and relate that invoice to the articles that are stored in the invoice. You can then further more relate the articles to where they are stored in your storage rooms, to how many this customer has purchased in total and so on. In short, you can relate any kind of existing data to each other as long as the values used for indexing are not blocks, words or objects. The data you are indexing can of course be of any type.

Remember that it says existing data. The relations engine doesn't make up data on its own, only creates the connections.

That's it! It isn't much, but I think it does it well.

Relations Engine can be found on the Download page.
