As shown in Figure 3-4, one or more individual data types are mapped into messages The same message can be mapped into multiple operations Types are typically any of the XML schemasupported data types, such as integer, string, Boolean, or date, and can include complex types, such as structures and arrays, including those defined for SOAP The data types are therefore either simple schema types or schemas that define complex types As in the other areas of WSDL, types are not restricted to XML schemas, because no one expects a single type of system to be capable of describing all possible message formats for the Web Figure 3-4 Data types are mapped to messages

When using SOAP, a message is carried as the payload of the SOAP request or response That is, the WSDL message definition does not include any information that is mapped to the SOAP envelope, headers, or fault code In other words, you can say that WSDL targets a layer of abstraction entirely above that of SOAP Information in WSDL does not map to SOAP headers
Defining Operations on Messages
The next level of abstraction, operations, addresses the requirement of a Web service to identify the type of operations being performed on behalf o a given message or set of messages The f operation is defined so that the Web service knows how to interpret the data and what, if any, data is to be returned on the reply Once you have the data, define the operations
Operations are defined in correspondence to common message patterns, such as one-way and request/response WSDL does not include specific definitions for other operations, but more

complicated interactions can be constructed by combining these basic types For example, something like the cooperating partner profile specification from ebXML could be used to define a sequence of one-way and request/response operations in support of a complex message pattern interaction As shown in Figure 3-5, operations can group messages for input and output to match the pattern of the request/response message Figure 3-5 Operations group message types to match the message pattern
WSDL has four types of operations:
One-way: Similar to fire-and-forget, but more simply it means that the message is sent without a requirement to return a reply Request/response: Similar to an RPC-style interaction; the sender sends a message, and the receiver sends a corresponding reply (Some protocols may not guarantee that a response is returned for every request) Solicit response (no definition yet): A simple request for a response with no input data It's a request to get a message and does not involve sending a message, in the sense of a WSDL message consisting of one or more defined types It's the reverse of the one-way operation Notification (no definition yet): This type of operation defines multiple receivers for a message, similar to a broadcast, and often involves a subscription mechanism, as in publish/subscribe, to set it up Operations match request/response and other message patterns
Operations allow sequences of messages to be correlated into specific patterns without having to introduce a more complex flow specification Operations are not the same as methods on objects, although certainly the input and output parameters defined for operations will normally map to method input and output arguments when the services are implemented using an object-oriented technology such as NET, EJB, or CORBA Operations correlate messages into specific patterns but not flows
