This will be the
name of the table created by the IEP Service Engine to store the IEP processing result.
Build the IEP module and deploy the module to a composite application.
For more information and some examples on an IEP based module, refer to
Chapter 10 ??“ Building a Sample Application.

Validating Event Processors
IEP Editor can validate .iep files for syntax and other errors including input/output
type mismatch for the operators. You can invoke the validation operation by clicking
on the Validate button at the top of the editor. When the validation operation
is invoked, the IEP validates against some predefined rules and the errors and
warnings are shown in the output windows, displayed as follows:
In the above mentioned IEP, the output stream is defined but not piped to the
TupleBasedWindow.
When you save an IEP process, the IEP Editor generates a WSDL that serves as an
endpoint for the IEP process. You are not supposed to change any section of the
generated WSDL document.

Operators Input and Output Types
Operators can take streams or relations as input, and output streams, relations, or
entire tables. Operators can be categorized by what their input and outputs consist of
according to the following table:
Operator Input Type ??“ Output Type
Relation Aggregator Relation - Relation
Time-Based Aggregator Stream - Stream
Tuple-Based Aggregator Stream - Stream
Relation Map Relation - Relation
Stream Projection and Filter Stream - Stream
Tuple Serial Correlation Stream - Stream
Stream Input None - Stream
Table Input None - Table
Relation Output Relation - None
Stream Output Stream - None
Table Output Relation - None
Insert Stream Relation - Stream
Delete Stream Relation - Stream
Relation Stream Relation - Stream
Table Relation - Table
Distinct Relation - Relation
Intersect Relation - Relation
Minus Relation - Relation
Union Relation - Relation
Union All Relation - Relation
Attribute-Based Window Stream - Relation
Partitioned Window Stream - Relation
Time-Based Window Stream - Relation
Tuple-Based Window Stream - Relation
From the above table, you can infer some examples of valid IEP rules:
