A selection of graphical message flow primitives defined within the message flow builder that each graphically represent and define message-oriented logic of an operation for the Web service are graphically assembled. Each graphical message flow primitive is defined within the message flow builder as a representation of a unit of work usable to define message flow patterns of Web service operation flow types and each includes a Web service operational processing logic definition of the representation of the respective unit of work usable to generate executable Web service logic. Selected ones of the graphical message flow primitives are graphically interconnected to represent a flow of messages to create a message-oriented Web service definition. The executable Web service logic defined within the message flow builder by each one of the interconnected selected graphical message flow primitives within the created message-oriented Web service definition is generated to construct the Web service.

A system and method of relationship management for data modeling in an integrated development environment is provided. A method of incorporating a program code file includes generating a relational schema of symbols in the program code file based on a framework for models in the integrated development environment, the schema comprising at least two related tables; determining a relationship between the at least two tables in the relational schema; adding definitions from the program code file for symbols in the relational schema to a definition set retaining definitions of symbols; and producing proxy definitions for use with the definition set for each symbol in the program code file without a definition in the definition set.

Relationship management for data modeling in an integrated development environment

A technique for serializing both logical and physical meta-model information in a single file is disclosed. In an embodiment, the logical meta-model information is serialized in an Extensible Marking Language (XML) schema compliant format, and the physical meta-model information is inserted into the logical meta-model in suitable locations such that the mappings between the logical and physical meta-models are preserved. In an embodiment, an XML 'appInfo' annotation is used to carry physical meta-model information used by multiple applications and suitably placed in a nested configuration with its corresponding logical meta-model information.

Single file serialization for physical and logical meta-model information

Embodiments of the present invention address deficiencies of the art in respect to Web services construction and provide a novel and non-obvious method, system and computer program product for message-oriented Web services construction. A method for the message oriented construction of a Web service can include graphically assembling a selection of message flow primitives defining an operation for a Web service, interconnecting selected ones of the message flow primitives to represent a flow of messages from one interconnected message flow primitive to another interconnected message flow primitive, and generating Web service logic from the selection of message flow primitives. The method further can include interpreting or executing the Web service logic in response to receiving a request to invoke the Web service.

A meta-model for creating models of alternative physical representations of logically equivalent entities, such as alternative wire format representations of logically equivalent messages, includes a logical meta-model and a physical meta-model. The logical meta-model provides logical entity component classes for creating a logical model which describes, in a platform and programming language neutral manner (e.g. as an XML schema), the logical structure of the modeled entity as a hierarchy of logical entity components. The physical meta-model provides classes for creating a physical model which describes the alternative physical representations. The physical meta-model includes Base Classes representative of generic physical representations of the logical entity components, with 'correspondence associations' being defined between the Base Classes and corresponding logical entity component classes. The physical meta-model further includes at least one set of physical representation-specific, Derived Classes descendent from the Base Classes.

The present invention generally provides a message validation model. Specifically, the present invention provides a message validation layer/framework that allows rules such as message validation rules to be plugged into/attached to a logical model. This model allows (among other things) schema level rules or the like to be converted to message level rules at deployment time. Specifically, the rules (like the physical representations) are serialized as annotations on the logical model. From this model, a query (e.g., XSL or XQuery) can be generated to validate and check if the instance documents comply with such rules or a Java based rules execution engine can be developed/utilized that uses XPATH (or another query language) to determine the source and dependent elements and executes the rules.

Message validation model

A method of validating a relationships table. The method includes generating a relational schema of symbols in the program code file based on a framework for models in the integrated development environment, the schema including two related tables. The method further includes determining a relationship between the two tables. Further, the method includes adding definitions from the program code file for symbols in the relational schema to a definition set retaining definitions of symbols. Additionally, the method includes producing proxy definitions for use with the definition set for each symbol in the program code file without a definition in the definition set. Furthermore, the method includes generating the relationships table in the relational schema containing the relationship between the two tables. Further, the method includes validating the relationships table by matching the symbols definitions and references, where the validation removes public symbols and referenced symbols from the relationships table.

Within the scope of existing XML Schema specifications, an approach is provided to embed simple types within a complex type so an XML stream can have instances of the embedded simple types, even without the presence of XML elements. Because the approach is within the scope of existing XML Schema specifications, the approach is transparent to known XML parsers. With the approach, an XML schema will have a complex type with a mixed flag set to true and an element set to be a dummy element. The dummy element has a simple type and one of (i) a name of the dummy element and (ii) a name of the simple type is one of a predetermined set of names. This XML schema is for use with a parser which, on parsing the schema, will interpret the dummy element as one of an embedded simple type and an inherited simple type.
