At work we have been using an MS Access database to track employee hours. This database was build in Access 95 in 1996. I have been tasked with creating a new system that isn't inherently internal (meaning our other offices would not need to remote in to use it). I've decided, based on my strengths, to use PHP / MySQL to do this.
Now the first problem is trying to copy all the data from Access to MySQL so we don't have to continue to maintain the old system (if we can avoid it). I'm unsure the best way to do this as I'm not very versed in Access and the queries running it aren't following general SQL standards. To make matters worse, the Access database wasn't even developed to follow 1NF so I can't in good conscience use the same schema as Access. Even worse there are about 70 tables in the Access db, however some of them are empty, and there are series of TableName1 TableName2 etc so I'm not even sure which ones are being used! Information is duplicated in so many places I can't follow the logic of the schema (if there is any)
My question to you guys is this: What is the best way to copy this data into the new system? How would you go about analyzing an older DB like this to make sure I'm copying over the correct current data?
