TeraGrid TeraGrid is an intelligent object-oriented database platform that sits on top of legacy databases (e.g. Microsoft SQL Server, MySQL) and allows developers and non-technical users to define data, security, and business rules. TeraGrid allows developers to access and manipulate data using web services from any custom application. When searching for, pulling, or saving data, TeraGrid's engine takes care of all the rules, including business, data, and security. TeraGrid can be used as a backend for any custom application. It can be hosted in-house or at a third party data center. It can run in a shared hosting account, on a large dedicated cluster, or in the cloud.
