Entity Relationship Diagram

Started this blog over the last couple weeks but I lost it.  I am therefore starting over.  After last Tuesday's class, I recognise how much work is required, more so the joy to be gained from finishing this project successfully.
It was noted that there should be a balance in the software and the report and the report must never be given lesser importance. 
I was able to imporve on the ERD-diagram for the IOS.  Further, I improved it by adding the attributes.  What I want to do now within the next two days is to normalise it and plug in data and write sql statements to achieve basic functionality.  Once that is successfull I will immediately start coding. 

I am thinking of going php rather than C# as mentiioned in the report.  But must remember to justify why this was changed.  The database for me is the weakest area.  The coding will require some revision but is can be accomplished with ernest effort. 

This system would represent a budget estimate system geared towards re-engineering the paper based annual budget preparation process for the Tobago House of Assembly.  What makes this unique is that the HR units of Ministries prepare the PE portion of the estimates.  This however is not done in the THA.  Rather each Division, situated at varying locations prepare their estimates and submit to head office(Budget)  Only if it is correct can the system be considered efficient, however it is never correct and requires several modifications.  Communicating the modifications to the Divisions is timely and is a correct representation is achieved after several weeks. 

Communication Technology can improve this process.  At the time THA had was not yet on board with IHRIS which makes their situation even more challenging.

I furtther added some attributes to come up with Phase 1(b)

Luckily for me tonight, I was able to log on to the wireless network in the area after trying for two days.
