Making a software database application such as CaliberRecruit scalable depends on the database used, such as Microsof SQL Server, Oracle or IBM's DB2 and how large volumnes of data are retrieved from the database server. (e.g. request to show every candidate registered by all consultants for the last five years!)
When such a request is submitted, CaliberRecruit automatically 'pages' the information so that the user does not have to wait unneccessarily for the lists to be displayed.
This means that CaliberRecruit can used thousands of users as easily as it can by just one!
