[Xotcl] Announcing Storm v0.1 — A transparent queryable object storage for Tcl/XOTcl

[Kristoffer Lawson]

Continuing on where Spindle leaves off, I created a system which again  
reflects how I believe storage should work. After endless problems  
with RDBMS and the object-relational mismatch, I decided to hell with  
that, and built a transparent persistence layer which can use a file  
or Sqlite backend (no reason why others could not be used too). The  
idea is that any class created from the basic PersistenceClass  
metaclass can be attached to storage. Changes are automatically  
written out. Even more interestingly objects which are referred to,  
but which do not exist in memory, are automatically loaded as well.  
You can even destroy them at will and, when required, they'll happily  
be loaded back in. There is also a simple query language for getting  
objects from their class.

It's not perfect, and a lot could be done with it still, but I like  
the idea. For many things full blown direct RDBMS access is just not  
necessary, and can cause major headaches. I also think that a lot  
could be done to optimise the Storm system so that performance  
differences wouldn't be huge, for many cases. Spindle (the web  
framework) does not require Storm in any way, and you can use any  
storage backend you want with it. I did, however, create them  
simultaneously so perhaps they subconsciously share some fabric.
