It is currently the only first-person page on this web site. I fear that people can be afraid of single-person project. Many of us think that it is more safe to work with company rather than with individual. But I in my life I had lot of opposite experience - for example I keep to use an excellent Total Commander, but my favorite Google Reader is dead.
I have started my programming career in 2002. Few years starting from 2003 I was doing lot of MS Access and VBA programming. Later I've applied that experience on Elance&oDesk (corrently both combined to Upwork). oDesk had own testing suite, I've got pretty good MS Access score (3rd place in one of tests) followed by number of successful contracts with positive feedback. I had to work with large amount of projects and had to track different versions of each project. I did not use usual version control system like git/svn/etc, but I was tracking all revisions with file system and had a big need of being able to compare different versions of the same project, all components - table structure, forms, modules, etc. I was trying to find a tool that could help me to track these changes, but they were either bad, or expensive, or both. So I've decided to make my own.
That was the burn of AccdbMerge. Few months later I've got an understnatind that it is somethting worth to share and I've made it public for free. After numerous downloads and lot of different feedback - mostly positive for those who had an invironment similar to mine, and some bug reports from those who had some other MS Access use cases which I was not aware of. It turned out that it requires lot of minor refinement and support work, much larger than to provide initial primary functionality. All this took too much time and I had to introduce the Pro version to compensate some portion of that time.
About one year later I had pretty good working AccdbMerge on the one hand and some MS-SQL experience on the other hand and I've decided to make a fork of AccdbMerge for MS SQL database - that was the MssqlMerge. And in 2018 I had some spare time to make it possible to do the same for MySQL and SQLite. MySQL was the first and once initial version was complete - it turned out that there are at least 3 projects on GitHub named "MysqlMerge" - my product naming system that was working in 2012 and 2014 for AccdbMerge and MssqlMerge - it was broken! So I've decided to call it just "KS DB Merge Tools".
Well, that's all for now..
