Build Integration Service using Group, Collector, Aggregate nodes; REST, JSON, CSV, COBOL; File, HTTP, MQ protocols
In this course, you will learn how to build integration services using message flows, sub-flows, message models shared, and static libraries. These integration services can accept requests from different kinds of clients, those clients can use different kinds of communication mechanisms like REST, SOAP, File, or queue-based communication. IBM ACE has the capability to handle this kind of communication protocol.

Requirements
In this course, you will learn how to build integration services using message flows, sub-flows, message models shared, and static libraries. These integration services can accept requests from different kinds of clients, those clients can use different kinds of communication mechanisms like REST, SOAP, File, or queue-based communication. IBM ACE has the capability to handle this kind of communication protocol.
The client systems can send requests in different message formats like CSV, fixed-length, JSON, XML, or any other delimited messages. If the end systems expect different kinds of messages and different kinds of data, we can use the transformation technique in ACE to modify it to desired message format. For this different kinds of nodes are provided namely compute node, java compute node, mapping node, and XSLT node. Compute node uses ESQL coding, the java-compute node uses java code and the XSLT node uses XSL.
Message models help in defining the message formats. Messages like CSV, fixed length, or any other text format mandatorily require message models to understand the message structure and to read the message contents in the program. For text and binary, we can DFDL message model. This course detailed different kinds of message models to create and using that how to transform the message to other formats.
Different routing mechanisms are explained and implemented using Group nodes, aggregate nodes, and collector nodes. The REST API implementation is explained and created service using swagger 2.0.
