Description
Technical field
The present invention relates to the technical fields of data of information system comparison method, and multisystem is based on more particularly, to one kind
The comparison method and system of data application.
Background technology
Power supply enterprise has multiple application systems, such as production system, marketing system, goods and materials system, toll collection system, each
A application system has the running environment and data storage method of oneself, to generate a variety of different databases.Each application
Development scheme, development environment and the development technique of system and to development specifications to defer to degree all different, each system it
Between close each other, data cannot be exchanged and be shared, to form big and small information island, by each system integration become development
Inexorable trend.However, there are the data of overlapping in each system of power supply enterprise, if integrating all systems, need to select it
In one group of data used as standard.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of ratio other side based on multisystem data application
Method and system, are not only compared data from the numerical value for comparing item itself, also utilize the relevant data of item compared with
Characteristic value auxiliary ratio pair can improve the accuracy of comparison.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of comparison method based on multisystem data application is provided, the multisystem includes production system, marketing system, goods and materials
System and toll collection system, the described method comprises the following steps：
S1. it is respectively that each system establishes tables of data, each tables of data interval setting time scans the data that each system obtains each system
, the variable of each tables of data corresponds to the data item of each system；
S2. the first tables of data and the second tables of data to be compared are determined, between first tables of data and the second tables of data at least
Including a comparison item；
S3. the data item of the first tables of data and the second tables of data is divided into n groups, and calculates the characteristic value of n group data item, respectively
It is expressed as E1、 E2、E3、……、En；
S4. the numerical value for comparing the comparison item described in two groups of step S2 goes to step S5 if numerical value is identical；If numerical value is different,
Two groups of tables of data are then reacquired to be compared；
S5. the characteristic value for comparing the n group data item in step S3 goes to step S6 if the numerical value of characteristic value is equal；If feature
The numerical value of value is unequal, then goes to step S3；
S6. whether judging characteristic value meets corresponding preset condition with the difference of corresponding threshold value；If satisfied, then judging the first number
It is consistent with the comparison item of the second tables of data according to table；If not satisfied, then judging the comparison item of the first tables of data and the second tables of data not
Unanimously.
The comparison method of the multisystem data application of the present invention, in addition to comparing the ratio between the first tables of data and the second tables of data
Compared with item, also compare the characteristic value of n group data item, the expression formula of each group of data item is optional and different, can give full expression to and
Compare the degree of association of a related data, can accurately react the consistency for comparing item.
Preferably, in step S3, the method to data item grouping includes：By the data of the first tables of data and the second tables of data
Be arranged together, and wait number be divided into n section, according to data put in order successively from n sections selection data be put into the 1st group, the 2nd
Group ..., n-th group.It is as a result also more accurate in this way so that the characteristic value of data item calculates the data used evenly.
Preferably, the first tables of data and the second tables of data are divided into three groups, the corresponding threshold value includes numerical value adjustable
One threshold value, second threshold and third threshold value, corresponding preset condition include adjustable first preset condition of numerical value, second
Preset condition and third preset condition.If the first tables of data is identical as the numerical value of comparison item of the second tables of data, and E1With
The difference of one threshold value meets the first preset condition, E2Meet the second preset condition and E with the difference of second threshold3With third threshold
The difference of value meets third preset condition, then judges that the first tables of data is consistent with the comparison item of the second tables of data.Pass through ratio
To comparing item number value and three characteristic values can accurately react and compare the consistency of item, and it is the first preset condition, second pre-
If condition and third preset condition are adjustable, thus can adjust the accuracy of comparison, the requirement of various environment is adapted to.
Preferably, the characteristic value E of three groups of data item1、E2And E3Expression formula it is different, in following formula
It is a kind of：A0+Ai∑Xi、B0+Bi∑Xi iAnd C0+Ci∑lnXi；Wherein, XiFor the data of corresponding grouping, A0、Ai、B0、Bi、C0And Ci
It is fitted to obtain by multi-group data.E1、E2And E3Expression formula according to actual conditions select it is most suitable, can give full expression to
Compare the degree of association of a related data.
Preferably, it in step S1, in each tables of data after each system obtains data item, is beaten for the corresponding data of each data item
Upper time mark；In step S2, the time mark of the first tables of data item compared with the second tables of data is identical.Time mark is stamped for data,
Convenient for determining tables of data that needs compare according to the time；Choose the before the first tables of data and second tables of data compare
Data in one preset time fit A0, Ai, B0, Bi, C0 and Ci, can select the first preset time according to actual conditions,
If data variation is fast, the first preset time is also corresponding short；Be spaced the second preset time period fit again A0, Ai, B0,
Bi, C0 and Ci, the second preset time of interval are updated each term coefficient so that the E of calculating1、E2And E3It can more accurately use
In comparison.
Preferably, after step s 5：
If judging, the first tables of data is consistent with the comparison item of the second tables of data, and sending comparison one to corresponding system writes
Breath；
If judging, the comparison item of the first tables of data and second tables of data is inconsistent, stores comparison result, and be to corresponding
System sends a warning message.
A kind of scheme fed back to the system for generating data is provided, if comparison result is inconsistent, just sends and accuses
Alert information, facilitates correspondence system to be modified.
The present invention also provides a kind of Compare Systems based on multisystem data application, which is characterized in that is filled including obtaining
It sets, computing device and comparison device：
