Hi all,

I am new to this forum and a rookie when it comes to Access. I inherited a pretty complex db and from my experience from other forums as well as trouble coming up with accurate queries I have come to the conclusion that normalizing the db is the only solution.

However, I really need help with this process.

I have attached a simplified version of my database with only the tables (all the #s and data are fake).

Basically what this db does is track lease hold improvements for various groups (ADT and RWA) and the tables are split up to reflect the 2 groups.

I will focus only on the ADT tables as the RWA is basically the same thing (Dont worry about GSA and the other stuff). The main table in the db is the ADT_Detail which includes all sorts of data regarding "Projects". I will provide information on each field:

Code:
Project- Project numbers numbers are unique, but often have multiple DCNs (and there's not always a project number so that can cause a null value for primary keys).

DCN - Each DCN can have multiple projects associated with it

TO - Task order can be the same for everything

SiteCode - A number that identifies various locations, there is another table that lists all the site codes and pertinent info on each.

CostBase - A currency figure on the original cost of each Project

Useful - length of useful life for each project

Complete-Expense - yes/no field 
Complete-Cap - yes/no field
WIP- yes/no field
(any project can have 1 or multiple yes for these)

InServ Date - Date the project is placed in service

Start Amort Date - Date amortization starts on the project

date add LHI - the date the project is entered into the db

Fund- a number where the project is expensed

Post Fund - If a fundis not available for the project this is what is used by the DCN and is usually the more important one

Year- when the project begins

Post year - If a year is not available for the project this is what is used by the DCN and is usually the more important one

Deletion - yes/no box so that we can keep a track of what items we are deleting to compare with other periods

Deletion date - used to identify Quarter that the project was deleted

There is also a table labeled (ADT_Master) which contains other data for each project. This is pretty self explanatory when you look at the table.

Everything is also based on quarters when we ran queries to show additions, deletions, adjustments in certain quarters based on the quarters table.

This is probably more info than what is necessary but hopefully it will give you an idea of whats going on. Let me know if you need any further clarification and I will try my best to assist.

Thanks in advance.

Hi Hibbi,
Perhaps you can buy proffesional software as Microsoft Project.

This system is much better and allows more.

Succes

All we have now is Access at work and they have been using this forever now. I am trying to find a way to better the process.

Any other inputs?
