Problems solved by technology

[0005] Establishing a metadata exchange mechanism requires a lot of development and management, and if system B itself does not need to care about metadata (for example, system B only records the SDO data sent by system A for simple operations such as auditing or system monitoring) , then establishing a metadata exchange mechanism will bring additional overhead to system B

Embodiment 1

[0027] see figure 1 , the embodiment of the present invention provides a method for sending data, including:

[0028] 101: Map the structure type of the service data object SDO data from the basic SDO data structure to the general SDO data structure.

[0029] 102: Send the SDO data of the general SDO data structure.

[0030] Further, the basic SDO data structure is business data DataObject, the basic type attribute Property, the general SDO data structure is node Node, attribute Attribute, and the structural type of SDO data is mapped from the basic SDO data structure to the general SDO data structure, including:

[0031] Map DataObject to Node;

[0032] Map Property to Attribute.

[0033] Further, map DataObject to Node, including:

[0034] Map the resource identifier URI of the DataObject type to the property URI of the Node;

[0035] Map the name Name of the type of DataObject to the attribute Name of Node;

[0036] Map the basic data type properties of DataObject to ...

Embodiment 2

[0047] see figure 2 , the embodiment of the present invention provides a method for sending data, including:

[0048] 201: When system A sends SDO data to system B, judge the structure type of the sent SDO data, if the structure type of SDO data is basic SDO data structure, then execute 202; if the structure type of SDO data is general SDO data structure, then Execute 203;

[0049] In the embodiment of the present invention, the basic SDO data structure is (DataObject (business data), Property (basic type attribute)), and the general SDO data structure is (Node (node), Attribute (attribute)). (DataObject, Property) is a strongly typed data structure. Each specific data in DataObject is stored in each Property under it. Property can be a basic data type (such as String (string), int (integer) , double (double precision number), etc.), it can also be a complex data type (such as DataObject type). When corresponding to an object-oriented language, DataObject is the "class", a...

Embodiment 3

[0068] see Figure 5 , an embodiment of the present invention provides a device for sending data, including:

[0069] The mapping module 301 is configured to map the structure type of the service data object SDO data from the basic SDO number structure to the general SDO data structure.

[0070] The sending module 302 is configured to send the SDO data of the general SDO data structure.

[0071] Further, the basic SDO data structure is business data DataObject, basic type attribute Property, the general SDO data structure is node Node, attribute Attribute, and the mapping module 301 includes:

[0072] The first mapping unit is used to map DataObject to Node;

[0073] The second mapping unit is used to map Property to Attribute.

[0074] Further, the first mapping unit includes:

[0075] The first mapping subunit is used to map the resource identifier URI of the DataObject type to the attribute URI of the Node;

[0076] The second mapping subunit is used to map the name Na...

Abstract

The invention discloses a data transmitting method, device and system, belonging to the technical field of computers. The method comprises the following steps of: mapping the structure type of service data object (SDO) data into a universal SDO data structure from a basic SDO data structure; and transmitting the SDO data of the universal SDO data structure. The device comprises a mapping module and a transmitting module. The system comprises a transmitting end system and a receiving end system. In the invention, the SDO data are transmitted after the structure type of the SDO data is mapped from the basic SDO data structure into the universal SDO data structure, so that the SDO data can be identified by the receiving end system without establishing a metadata exchange mechanism, and the cost on the receiving end system is reduced.

Description

technical field [0001] The present invention relates to the computer field, in particular to a method, device and system for sending data. Background technique [0002] SDO (Service Data Object, Service Data Object) is a data programming framework and program interface. SDO can provide consistent data-specific The programming of SDO can also provide support for common application patterns, making it easier for applications, tools and frameworks to query, browse, bind, update and introspect data, so SDO has been widely used. [0003] At present, when system A needs to send SDO data to system B for use, it will notify system B of the metadata of system A's SDO data in advance through a metadata exchange mechanism, so that system B will receive the SDO data of system A , the SDO data can be correctly parsed and used according to the metadata. [0004] However, in the process of realizing the present invention, the inventor finds that the prior art has at least the following p...
