"I have written over 60 access programs and I work on about 10 different ones at any given time. I make different changes to the same application on multiple client sites. In the past, trying to walk each application to check on changes from each site was not only time consuming but was a nightmare. With AccessDiff I have spent about 4 hours in the last 30 days keeping track of the differences in my applications, where in the past I would have spent better than 40 hours. I am extremely happy with the ease of use of your program as well as how fast it brings back the results. I cannot imagine how I ever got along without it."
Easily compare access databases with AccessDiff. AccessDiff can compare two databases, two objects within a database, or two folders of databases. It also detects missing objects in either the source or destination. Records are compared based on the primary key. If there is no primary key for a table, the comparison is performed on the Natural Key. After the database comparison is performed, the differences can be exported into several different formats.

"We were engaged by a client to help them migrate off a proprietary accounting system built on Visual Basic 6.0 and an Access 2000 database. AccessDiff made it simple for us to understand how the data flowed through the system, and reduced the amount of time we had to spend digging through code to understand the business rules built into the proprietary system."
