In my last post,
CEP Event Sources, I started a (short) list of event sources, both in theory and in*practice, for complex event processing.** There were some good comments and the list if evolving and improving.
Event transformations are used to convert inbound*event objects*to an outbound*object type required required by*a transport layer, such as a JMS Message*or a stream, such as a market data format, or*other event feed handler.**
Event transformations* typically happen in the
event preprocessing stage, of an application; but in a generated architecture, events can be preprocessed thoughout the event processing lifecycle.** Multiple transformations can be combined, chained or piped together as required.
Below is a list of commonly used event transformations.* Please feel free to comment as we add (or subtract)*to (or from)*the list.
- XML Transfomations
- Scripting Transformations
- PHP
- PERL
- Regular Expressions (Regex)
Also, should we include the subclasses of tranformations below in the overall class of event transformers?
- Cryptographic Tranformations
- Encoding Transformations
- CVS Transformations
- Vendor Specific Transformations
Please contribute to the list with your comments.
