Project Update 1 - A Home Security System

A Home Security System

Keywords: BeagleBone Black, Python, Tkinter, Raspberry Pi, RPi, Arduino, Security System, Home Automation

Change to architecture
April 6, 2014 (Back to Table of Contents)

I recently came back to this project after taking a break to do other things.

The current architecture (same as before):

• Python is the primary language
• It will run on a BeagleBone Black

The changes to the architecture:

• Is a distributed application
• Using Kivy for the presentation layer (GUI)
• Monitor will be available on any GUI device (e.g., Linux, Windows, Mac, Android)
• Uses Json for IPC and network communications

Search for a Python Oriented OODBMS

• Have decided to go with BeagleBone Black instead of Raspberry Pi.

After much research regarding Object Persistence (OODBMS) for Python, I've elected to use the built-in capability of Python Shelve.

Frankly, I'm surprised that there aren't more active Python OODBMS applications!

I investigated the following candidates, all of which must be open-source, and the reason, from my opinion, for my rejection:

• Zodb - overkill for this application
• MongoDB - overkill for this application, not a OODBMS
• Buzhug - not very active, no support for Python 3 yet.
• Pypersyst - not active
• CouchDB - document oriented database
• Objectivity - no support for Python 3 yet, commercial product
• Axiom - not a OODBMS; a mapper between SQL database and objects
• Durus - Requires a download of DurusWorks, which appears to be a complete environment.  For my application, this is more of a challenge than I want to undertake.  It may be a great product though!
• Cog - no support for Python 3 yet.  Does not appear to be very active.
• Poodle - no support for Python 3 yet.
• Dobbin 0.3 - Was a potential candidate.  Says it's compatible with Python 3.x. However, no activity more recent than 11 months ago.
