## Data Modeling in JavaScript

jSchema is a framework for modeling data in JavaScript.  By using fundamental data modeling principles you are able to pull multiple datasets into a common schema, define relationships, aggregate, join, and subset datasets to make data easier to work with in the browser.

![entity relationship diagram - new page 1](https://user-images.githubusercontent.com/5210420/32084304-50e6bdbc-ba96-11e7-92b8-cfab13866fe0.png)

jSchema is going to create an object called `jSchema`.  This object is a metadata representation of all your datasets containing the table names, column names, and keys that define sets.  The data itself is stored in a closure within the object and is retrieved via a getter function.  Joining data, aggregating data, and filtering data will create a new dataset in your WORK namespace that will persist on the page until either you delete the table or you run a cleanUp method.  By default jSchema will be case sensitive.  This can be overwritten with:

```JavaScript

var s = new jSchema({

  "caseSensitive": false

});

```

## Demo

A complete working demo of how to load tables, join tables, and aggregate tables can be found in the repository in the demo folder.  A live demo can be found on the libraries homepage: [live demo](http://resurgencewebdesign.com/refugee/)

## How to Use

### NPM

If you use npm, `npm install jschema`.

### requirejs

jschema.js uses requirejs to modularly load the library and is included in the package.json.  requirejs can be moved to the lib directory of your project and included as:
