devRant - A fun community for developers to connect over code, tech & life as a programmer

A couple of months ago, the father of a friend of mine, asked me if I wanted to help him out with a project.

His late father, whom he inherited a one-person upholstering company from, once created a system in filemaker to do, among others, his financial administration. This system, however, grew organically as time went by, but he passed away before he explained to his son how it worked.

Now this man was running the company, using the parts of the system that he knows, but things were starting to break down. He asked me if I could help him understand what is going on and fix a couple of things.

However, the more I look at it, the more I realize what a monstrosity this has become, because the system has never been cleaned up. For example:

- There is a suppliers table, with the columns "E-MAIL" and "EMAIL". The latter one containing the supplier's website address.
- In order to be able to generate year reports, at the start of a year he copies the previous year's file, removes all records from it and starts using that as the new year's file. (This year, he accidentally created a shortcut instead of copying...)
- Some tables have a misterious column called "#1". It always contains a 1.
- The system consists of about 20 files, each of them containing a single table, although only 10 of them are really used. The other ones are just legacy.
- File, table, column, and layout names are capitalized randomly (all caps, no cap, starting uppercase) and are usually abbreviations, like "st2", "oms3", "off\rek", "b", "VERDBEST6" and "antst".
- One table has 92 columns.
- Of those 92 columns, only about 20, maybe 30, are in use.

Now, my task is finding out what parts are useful and in use, extracting those and create a baby monster out of the giant monster this system has become.

Sidenote: I actually enjoy having to learn a bit about accounting in order to understand this. Planning to use the knowledge I gain to keep track of my own finances.
