copied!<p>I don't want to be unhelpful and you haven't given any background about your business needs, but you have to decide if your priority is really "fast and secure" or if it's actually "cheap". Replicating changes between multiple databases in a reliable, consistent way is not easy (as you know) and it's highly unlikely that you will be able to develop a solution yourself that has the features, stability and performance of SQL Server replication.</p> <p>SQL Express can be a replication subscriber, by the way, so it's not clear why it doesn't meet your needs. But if it doesn't, you should estimate the cost to your business (or customer) of dealing with issues caused by an unreliable solution: your time, business downtime, finding and correcting incorrect data, customer complaints, lost business etc. Then compare that to the cost of 25 SQL Server licenses (you should certainly be able to get a good discount when you order that volume), additional hardware (if any) and the costs of training, consulting and/or learning how to use replication. Then extrapolate those costs over 5 years or so. You may find that it's cheaper just to buy the solution you need. And of course buying the full SQL Server edition means you get a lot of other new features that might be useful to you.</p> <p>If you (or your boss) is really determined to get something for nothing, you might want to investigate PostgreSQL or MySQL. They both have free replication solutions that seem to be widely enough used to be reliable for many companies. Of course, you then need to calculate the costs of switching to a new database platform.</p>
