Hello,
UniDAC has a lot of benefits. Here are some of the most significant ones:
- Connection to Oracle, MySQL, PostgreSQL, SQLite, and NexusDB without involving a DB Client library;
- Only UniDAC supports connecting to SQLite, Oracle, MySQL, PostgreSQL and InterBase from iOS and Android;
- Support for dbMonitor, that allows our users to see all SQL statements, which were sent to a DB server;
- Local Failover for connection loss detection and implicit re-execution of certain operations;
- Highest performance;
- Lesser memory consumption;
- Highest stability;
- High-quality technical support, that helps our users resolve all their issues as soon as possible;
- and others
UniDAC has a lot of options that allow to tune performance and behaviour as you want. Devart is in the market for over 16 years and has always been the leader in the field of Data Access Components development, therefore we have never compared our components with competitors. Our competitors usually tried to catch up with us and implement those features, that we already had long time ago. If the feature by feature comparison is interesting for many people, we will probably make such a comparison, but this is a rather time-consuming issue, as every product has a lot of options and features.
You can also see independent tests on memory consumption and performance at
