SQL Relay

SQL Relay is a powerful database connection management solution.

With SQL Relay, you can speed up and enhance the scalability of database-driven web-based applications, access databases from unsupported platforms, throttle database access, distribute load over clustered or replicated databases, route queries and migrate applications from one database to another.

Advantages

Persistent Database Connection Pooling - makes database-driven web-based applications faster and more efficient
Proxying - provides access to databases from unsupported platforms
Throttling - prevents databases from becoming overloaded
High Availability - provides load balancing and failover with replicated or clustered databases
Query Routing - conditionally sends queries to one database or another
Query Filtering - prevents queries that match certain patterns from being run at all
Connection Schedules - constrain database access to specified times

Database Support - a wide variety of commercial and open-source databases are supported
Abstraction Layer Support - drivers for most popular database abstraction layers are provided
Drop-In Replacement Libraries - allow many native MySQL or PostgreSQL applications to use SQL Relay without modification
Native API - the powerful native SQL Relay client API supports a wide variety of programming languages

Substitution and Bind Variables - make frequently run queries faster and more efficient
Multi-Row Fetches - reduce the number of network round-trips
Client-Side Result Set Caching - makes paging faster and easier
Suspended Transactions - allow a single transaction to span multiple web pages

SQL Relay Enterprise Modules provide advanced features not available in the standard distribution.

MySQL Front-End Modules - allow MySQL applications to use SQL Relay without modification and without a drop-in replacement library
