Computing module output result numbering.
The output result using the computing module of calculation of the same race preserves with version, and forms version set.
The result of calculation in the version set that calculation of the same race obtains is used to have no time dependence, and the most only
Vertical.
Database manipulation interface for data load and data store, data load by alternative input data according to
The key message obtained in UI is loaded into by versions of data control table in the submodule input treating computing.
Dependence between simulation calculation of the present invention represents with tree.Whole single simulation calculation process is chain type,
Calculate node on chain calculates the input result of calculation from previous node.The result of calculation of previous node can be divided into many
Individual version, can produce multiple input branch, can carry out a set of independent simulation calculating for each branch.
Input data are loaded into the submodule treating computing by Version Control table, simultaneously when storage to data base, and
Shi Gengxin version table.
Load for data and data storage separately designs two set functions to realize application server interface design.
It is designed as a example by ALS below:
1. database table design
1) design basis
Linear and comfort level checking process the workflow of ALS circuit is the design basis of versions of data control table,
Being known by Specification, its workflow can be divided into 6 sub-calculating processes, respectively with in versions of data table 1
In 6 lists show, as follows:
Table 1
Every a line record in table is used to represent certain calculating process, for determining that relating to this time calculates the number of process
According to stream, correspondence position in row is stored in its numbering calculating output result by the computing module participating in computing.
Based on this method, by checking the data record case often gone, both from column, whether can have data
Obtain this time and calculate the progress of process, it is also possible to the data from row obtain each submodule during this time calculates and produce
The data result of raw particular version.
2) it is described with reference to Figure of description
As it is shown in figure 1, rectangle frame represents an independent calculating branch, the circular node being connected in branch represents
A result of calculation (a corresponding version) on current branch.Have no time between the result of calculation of each version
Dependence, and do not rely on the result of calculation of other versions.The circular node table that in figure, 0 ', 2 ', 1,2 ' and 0 ' are residing
Show that subsystem is committed to the result of calculation of total system, be available for other subsystems as design input.In figure, straight line institute
Being shown as chain type and calculate process, after producing each version branch, whole version view launches with tree-shaped.
With reference to table 2, the present invention is further explained.
Table 2
For calculating process every time, represented by row independent in form, in representing below for often row information
Appearance explains:
A) from 0 version of designing institute
B) from 1 version of designing institute
C) from 2 versions of designing institute
D) from 3 versions of designing institute

The related data information of all of calculating process and procedural information all can be drawn by the data of often row record.
2. database manipulation Interface design
Data load and are mainly used according to the key message obtained in UI, alternative input data are passed through Version Control
Table is loaded in the submodule input treating computing, is chosen suitably input data by user and count in Practical Calculation
Calculating, the effect of Version Control table is to ensure that version concordance, forbids that data separate between load application version are for user
Use.
When storage to data base, need the version table that upgrades in time.Therefore, the data of result of calculation store project
After data base, need according to currently calculating the version information relied on, together with object information with the form of new record
Add in Version Control table.
3.ALS application server interface designs
Application server interface is to be exposed to subsystems, has been used for that ALS circuit is linear and comfort level verification
In flow process data load and data storage remote method, subsystems in the calculation for data base operation all
Completed by these interfaces.
(1) calculating desired parameters is loaded
Each calculating process in and comfort level checking process linear for ALS circuit, data load can be divided into two
Step operation, is completed by two set functions:
1) same to user interface interaction, from terminal obtain must load calculating data source, numbered by selected data or
Keyword, notify synthetic simulation environment, synthetic simulation environment will by one or more data numbers or keyword,
The data number that inquiry is relied on is obtained from Version Control table.The function, method and the query statement that relate to are by always
Body completes.
2) after control table obtains the numbering that data are relied on, according to these numberings (inputting as function), in project
Data base obtains the operational data of reality, and is loaded into user interface.The function related to and query statement are by each
Subsystem responsible is write, and is totally responsible for integration.
(2) preserve calculating and complete result
Each calculating process in and comfort level checking process linear for ALS circuit, data storage also can be divided into two
Step operation, is completed by two set functions:
1), after having calculated, current result of calculation and data are saved in the corresponding table of global database.Relate to
Function, database manipulation is completed by subsystems, is totally responsible for integration.
2) after preserving results of calculation, it should be provided to complete to calculate involved input to synthetic simulation environment
Data number, and output data number, and notification version control function.Version Control device will be compiled in conjunction with input data
Number, complete the filling of predecessor information and add the data number of result of calculation, increasing new in Version Control table
Record.
