Embodiment 1
[0025] figure 1 A flowchart of an access method of a multi-source heterogeneous data provided by the embodiment of the present invention, the present embodiment can be applied to access the multi-source heterogeneous database, and the data in the multi-source heterogeneous database is changed. The method can be performed by an access device of the multi-source heterogeneous data in the embodiment of the present invention, which can be implemented in software and / or hardware. like figure 1 As shown, the method specifically includes the steps of:
[0026] S110, acquire the first data access request for the user by the access interface of the unified interface layer.
[0027] Wherein, the unified interface layer can provide the user interface layer, providing the user to the user interface service to the user, implement the user's access operation of the multi-source heterogeneous database, and displays the return result.
[0028] The access interface provided by the unified inter...
Embodiment 2
[0044] figure 2 A flowchart of an access method of a multi-source heterogeneous database according to the second embodiment of the present invention, the present embodiment is optimized by the above embodiment, in the present embodiment, by the target driver pair The data access request is converted to obtain the second data access request, including: querying each database name pre-stored in the target driver according to the root node name, determines the target database; according to the access interface and the target database, The access interface protocol corresponding to the first data access request is determined; based on the access interface protocol, the data access parameters in the first data access request are converted to obtain a second data access request.
[0045] like figure 2 As shown, the method of this embodiment includes the steps of:
[0046] S210, acquire the first data access request of the user by the access interface of the unified interface layer.
[...
Embodiment 3
[0122] Figure 4 A structural diagram of an access device for a multi-source heterogeneous database provided in the first embodiment of the present invention. This embodiment can be applied to access the multi-source heterogeneous database, and the data in the multi-source heterogeneous database is changed. The device can be implemented in software and / or hardware, which can be integrated in any provider. In the device of the access function of the source partitioned database, such as Figure 4 As shown, the apparatus for accessing the multi-source heterogeneous database includes: uniform interface layer 310, data drive layer 320, and data storage layer 330.
[0123] Wherein, the unified interface layer 310 is used to obtain a first data access request for user input by an access interface, and at least the first data access request includes at least the root node name and table property, the table properties including: Table Name and field Array, store field properties in the fi...
