Abstract: A system and method for processing a distributed transaction for an application are disclosed. Conventionally transactions on critical data (e.g. financial information) are processed using a database architecture whereby a persistent database (typically a redundant disk array) comprises the master record. In cases where large amounts of data need to be accessed but absolute data integrity is less critical, for example search engines, processing is conducted on live in-memory data without all the data being backed up, which can be much faster but data can be lost when processors fail. There have been attempts to use data grid architectures with some backup to persistent stores for more important data but these have either introduced disk access bottlenecks or required manual intervention in the event of failure.

Abstract: Aspects of a model development and code generation system and method are described. One aspect of the system generates program code for implementing a software system specified by specification data, which may represent a model of a system designed by a user. The system includes an input component adapted to receive the specification data, a processing component adapted to generate further specification data in dependence on the received specification data and a code generator adapted to generate the program code from the specification data and the further specification data. The code generator may use templates and controls to generate program code and the further specification data may be generated based on a meta-model developed by the user.
