TS Integrator
Tradeshape has developed a point to point version of its TS Integration Server, aimed specifically at simple one-to-one data transfer and translation.

Here is a list of the features:
• Data segregation between different entities
• File based configuration
• Full data validation
• Translation of data
• Batch processing
• Batch creation by time, file size etc.
• Aggregation across outbound data
• Propagation of information for master/child relationships
• Data input from many sources using industry standard interfaces such as File, FTP, JDBC, Sockets, MQ
• Java EE implementation for platform neutrality
• Easy upgrade to TS Integration Server if required
• Open standards and technologies throughout the system (eg. Java, XML, XSLT, XML Schema, Relax NG) - no proprietary technology to learn
