The HireTrack NX server is database server application built up on the NexusDB database engine.
"Why do you use NexusDB? Why don't you use standards like Oracle, MSSQL, ..?"
The reason why people want "standard" databases is so they can "minimize risk". They "minimize risk" by using a product that they are comfortable with, rather than use the best tool for the job.
Oracle and MSSQL are both fine databases, but they are too bloated and too pricey for many of the applications that use them.
Licensing costs for either database will cost several thousands of pounds and either will require a trained database administrator (DBA) to install and keep running optimally.
For vertical applications, such as HireTrack NX, the NexusDB engine completely removes the need for a DBA, it is extremely easy to install and maintain and is included free of charge with the client application license.
There are several reasons, in no particular order, why the NexusDB engine was selected as our engine of choice:
SQL Support
| • | Standard SQL:2003 - statements supported |
| • | Triggers, Stored Procedures and Functions - fully implemented. |
