python daemon - compress data and load data into MySQL by pyodbc

[MacRules]

Hi,

I installed Python daemon, pyodbc module to access the back-end DB server.

My setup is like this

load data job -> Python Daemon A, port 6000 -> Python Daemon B, port 
7000 -> MySQL

Daemon A will perform data compression, such as GZIP, and send over data 
to Daemon B.
Daemon B will perform data uncompression, GUNZIP, and insert records to 
MySQL or MSSQL or Oracle.

Where should I start this to code this?
Can someone give me a hint, as detail as possible here?

I am a python newbie.

Thanks for all the help I can get,
