RSQL, a Microsoft SQL clone

Data Stacker


In lone wolf mode, Riesch has achieved remarkable results with RSQL. According to him, the execution speed of his MS SQL clone is slightly slower than the original, but the general performance is completely adequate for most applications. Our tests confirm this statement, so we can recommend RSQL as a free alternative to MS SQL Server. The DBS matured in secret for a long time and still has a couple of burrs that Riesch needs to file, but the software is already proving to be suitable for everyday use.


The authors thank Nicolas Riesch and Werner Staub for all the detailed information and for their patience.
