[Active Database](http://github.com/andykant/active-database) (ADb)
=================

About
-----
ADb is a relational database system implemented in JavaScript. ADb's implementation is based on the ActiveRecord design pattern.

* Version: 1.0.0.20

Credits
-------
* ADb.$type is based on $type from mootools.js, [http://mootools.net](http://mootools.net) (c) Valerio Proietti, MIT-style license.
* ADb.$xfn is equivalent to $xfn from xfn.js, [http://github.com/andykant/extended-function-factory](http://github.com/andykant/extended-function-factory) (c) Andy Kant, MIT-style license.

Notes
-----
* ADb is not a transactional database system. This is primarily because there
isn't a reasonable way to clone objects while maintaining their original
context. Due to this, assume that changes made to a row have the potential
be applied to the database immediately. However, always call the $save
method on the row to ensure that the database is updated.
* ADb is a relational database system, but the relations are not enforced.
* It is not recommended to export tables with functions, textnodes, or
elements because those objects cannot be exported. Likewise, any objects
containing any of these datatypes will probably not export properly
either. These datatypes will be exported as 'null' instead with the
exception of functions used as default value generators.
* Primary keys are limited to a single column with one of the following
datatypes: number, string, auto (auto-incremented number).
* Foreign key references in a table declaration should create a ADb.$ref
object if the foreign key's table has not been initialized yet. ADb.$ref will
ensure that the table has been initialized, and will then return the first
matching entry.
* Columns of the datatype 'auto' should be passed 'null' when creating
new rows.
* Any method or property marked as DESTRUCTIVE might cause unintentional
results. Destructive methods might change the structure or data of a
database or table. Changing the value for a destructive property might
prevent the database from working correctly.
* Error messages are only enabled when ADb.$debug is set to 'true'. Error
messages will be passed to Firebug if it is available.
