when the user edits and generates operation P locally 3 The client: n U P 3 →N=NP 3 ；
The client uploads N 'and o=n' to the server while submitting the operation change to the local, provided that the client receives a confirm signal from the server for O;
when the client receives the confirm request signal from the server, the client: b → b=bo, i.e. B is updated to BO;
when the client receives P submitted by other clients, defining the P as C; at this time, the content in BNO should be updated to be B 1 N 1 O 1 I.e. recalculate P, defining the procedure as D such that bnod=b 1 N 1 O 1 : the calculation sequence is as follows:

The system comprises four modules: the system comprises a design standardization management module, a data management module, a fusion sharing module and a permission management module. The architecture follows a business architecture which is standardized in design, high in data management effectiveness, high in fusion sharing degree and excellent in system authority management.
In the design standardization management module, after the scene assembly is built, a table dragged into a data source and fields in the table and required positions are selected through a new data set in data management, and association relations required by the fields are designed. The saved data set (the established data model) is dragged into the corresponding component to realize the data model modification. After the operation of 'sharing' the scene is carried out, the scene appears in a multi-person collaborative plate which is fused and shared, the scene can be edited in a collaborative way by the users with open rights, and after the editing is completed, the scene is subjected to 'release' operation, namely, the scene appears in a template library (in a non-editable state). The user operation information can be inquired and known in a log management module of the system authority module.
The specific scheme of each module is as follows:
1) Design standardization management module
