> Datamata SQL Portal > About > Architecture


Datamata SQL Portal application architecture consists of 3 tiers:

  • Database tier, which comprises all possible database instances connected to Datamata.

  • Application Server tier, which is a Tomcat or other J2EE server running Datamata SQL Portal application. Datamata communicates to databases over JDBC.

  • Client presentation tier, which consists of web browsers. A web browser creates user presentation of HTML received from Datamata SQL Portal and sends back user responses. A web browser communicates to Datamata over HTTP, which is a basic Internet protocol and which can go through all firewalls.
