Data sharing between applications where only one application knows the business purpose of the data

A first computer system comprising:

• a central processing unit (CPU);
• a memory coupled to said CPU;
• a computer-readable, tangible storage device coupled to said CPU, said storage device containing instructions that when carried out by said CPU via said memory implement a method of sharing data between applications, said method comprising:
• sending, from a calling application being executed on said first computer system and to a callee application being executed on a second computer system, a request for a processing of a first set of data owned by said calling application and stored by said calling application in a data table of a data repository coupled to said first computer system, wherein said first set of data includes a plurality of data elements;
• generating, by said calling application, a document associated with a function of said calling application;
• loading, by said calling application and subsequent to said generating said document, a plurality of containers that includes a plurality of data elements into said document, wherein said loading is performed in a predefined order or with a plurality of predefined labels;
• and
• sending said document by said calling application, to said callee application, and subsequent to said loading said plurality of containers,
• wherein said sending said document facilitates:
• a translation of said plurality of containers into a plurality of element types via a mapping interface table, wherein said containers are associated with said element types in a one-to-one correspondence,
• an unloading of said plurality of data elements from said plurality of containers into a data store via said predefined order or via said plurality of predefined labels, wherein a result of said unloading of said plurality of data elements is an association in said data store of said plurality of data elements with said plurality of element types, and
• said processing of said first set of data subsequent to said unloading, wherein said processing includes an application of a business rule to a data element of said plurality of data elements based on said business rule being associated with an element type of said plurality of element types, wherein said element type is associated in said data store with said data element, wherein a result of said processing is a second set of data that includes an update of said plurality of data elements, wherein said calling application does not know said business rule and wherein said callee application knows said business rule.

A computer program product, comprising:

• a computer-readable, tangible storage device having a computer-readable program code stored therein, said computer-readable program code containing instructions that when executed by a processor of a first computer system implement a method of sharing data between applications, said method comprising:
• sending, from a calling application being executed on said first computer system and to a callee application being executed on a second computer system, a request for a processing of a first set of data owned by said calling application and stored by said calling application in a data table of a data repository coupled to said first computer system, wherein said first set of data includes a plurality of data elements;
• generating, by said calling application, a document associated with a function of said calling application;
• loading, by said calling application and subsequent to said generating said document, a plurality of containers that includes a plurality of data elements into said document, wherein said loading is performed in a predefined order or with a plurality of predefined labels;
• and
• sending said document by said calling application, to said callee application, and subsequent to said loading said plurality of containers,
• wherein said sending said document facilitates:
• a translation of said plurality of containers into a plurality of element types via a mapping interface table, wherein said containers are associated with said element types in a one-to-one correspondence,
• an unloading of said plurality of data elements from said plurality of containers into a data store via said predefined order or via said plurality of predefined labels, wherein a result of said unloading of said plurality of data elements is an association in said data store of said plurality of data elements with said plurality of element types, and
• said processing of said first set of data subsequent to said unloading, wherein said processing includes an application of a business rule to a data element of said plurality of data elements based on said business rule being associated with an element type of said plurality of element types, wherein said element type is associated in said data store with said data element, wherein a result of said processing is a second set of data that includes an update of said plurality of data elements, wherein said calling application does not know said business rule and wherein said callee application knows said business rule.

A process for supporting computing infrastructure, said process comprising:

• a processor of a first computer system providing at least one support service for at least one of creating, integrating, hosting, maintaining, and deploying computer-readable code in a second computer system, the computer-readable code containing instructions, wherein the instructions, when carried out by a processor of the second computer system, implement a method of sharing data between applications, said method comprising:
• sending, from a calling application being executed on said second computer system and to a callee application being executed on a third computer system, a request for a processing of a first set of data owned by said calling application and stored by said calling application in a data table of a data repository coupled to said second computer system, wherein said first set of data includes a plurality of data elements;
• generating, by said calling application, a document associated with a function of said calling application;
• loading, by said calling application and subsequent to said generating said document, a plurality of containers that includes a plurality of data elements into said document, wherein said loading is performed in a predefined order or with a plurality of predefined labels;
• and
• sending said document by said calling application, to said callee application, and subsequent to said loading said plurality of containers,
• wherein said sending said document facilitates:
• a translation of said plurality of containers into a plurality of element types via a mapping interface table, wherein said containers are associated with said element types in a one-to-one correspondence,
• an unloading of said plurality of data elements from said plurality of containers into a data store via said predefined order or via said plurality of predefined labels, wherein a result of said unloading of said plurality of data elements is an association in said data store of said plurality of data elements with said plurality of element types, and
• said processing of said first set of data subsequent to said unloading, wherein said processing includes an application of a business rule to a data element of said plurality of data elements based on said business rule being associated with an element type of said plurality of element types, wherein said element type is associated in said data store with said data element, wherein a result of said processing is a second set of data that includes an update of said plurality of data elements, wherein said calling application does not know said business rule and wherein said callee application knows said business rule.
