Technical field
The present invention relates to a kind of advanced application system (as systems such as decision support, data mining, report form statistics) and basic service system (as advance, pin, deposit system, management information system, the office automation system) Data Interchange Technology between relates in particular in the industry system information management such as electric power, telecommunications, finance, aviation, retail in order to the efficient that improves data-switching, multiple source data conversion service method and the device thereof that reduces development and maintenance cost, economize on hardware and the Internet resources of advanced application system.
Background technology
Current, the dispatching communication center of electric system, having set up with energy management system EMS (EnergyManagement System), scheduling information management system DMIS (Dispatching Management InformationSystem), Electricity Market Operation System etc. is the basic service system of representative.Except these basic service systems, (be called for short: the power-management centre) each department is in order to satisfy concrete need of work at the dispatching communication center of electric system, also need on the basis of above basic service system, set up some comparatively senior application systems at particular demands, as visual monitor system, Analog Simulation System, data analysis system, reporting system, data digging system etc.The data that these advanced application system are required often are derived from one or more basic service system.Therefore, in setting up the process of advanced application system, how from a plurality of basic service system acquisition, cleaning, translation data, promptly data integration job is a problem that must solve.
Referring to Fig. 1, on the one hand, foregoing basic service system is the business demand at different departments, as, energy management system, schedule information system, Electricity Market Operation System and other operation system are set up by the independent development of different exploitation units.Therefore, cycle of the type of each system database system, data tableau format, data acquisition etc. is all inequality.This situation is given the data integration job of advanced application system, has caused difficulty, for example:
1) data layout disunity between a plurality of data sources, the development difficulty of increase advanced application system;
2) the advanced application system server need dispose the data-driven program that is applicable to the disparate databases type, and occupying system resources increases system burden;
3) application's data importing work, occupying system resources influences running efficiency of system;
4) in a plurality of data sources, all the data that exist are in various degree omitted and the bad data problem, have reduced the operation stability of advanced application.
Referring to Fig. 2, on the other hand, because each advanced application system is also successively proposed and stand-alone development according to actual needs by each business department, therefore, each advanced application system is all independently carried out data importing, cleaning and the conversion work of multi-data source.
There are following problem in exploitation and operation for advanced application system:
1) each advanced application all needs to prepare the data-driven program in Various types of data source, and the installation of data-driven, renewal and maintenance work must be responsible for by advanced application system.The installation of driver itself can take the resource of system server, and the operation of driver and version conflict can be to reducing the operation stability of advanced application.
2) each advanced application all needs to collect and understand the database structure of each operation system when exploitation, the tables of data form, even the implication of each initial parameter, so that understand this Service Database and derive desired data, increased the development amount of advanced application.

2) wasting of resources and operational efficiency problem
In practice, each advanced application all is independent project verification, independent budget.If advanced application system itself need operate on 1 station server, if not extra budget increase, data integration job also needs to move under same station server so.The operation of advanced application system certainly will be received the influence of data integration job and be lowered efficiency.If another station server of additional configuration then can cause the bigger wasting of resources.
3) increase of maintenance cost
Under existing scheme, when the basic service system renovates, if relate to the variation of database, the variation of LAN (Local Area Network), even very little variation, the capital is caused the advanced application system based on these operation system data and is seriously influenced, and all advanced application system all need to carry out corresponding transformation.From another angle, if a certain advanced application system, the data of 5 basic service systems have been used, so these 5 operation systems any one upgrade, advanced application system all has to carry out corresponding modification, frequent system upgrade transformation can influence the normal operation continuously of advanced application system, the increase that also can bring maintenance cost.
Therefore, for solving above data integration problem, that is: with disparate databases system in each basic service system, the data of different-format, carry out data importing respectively, data cleansing and data-switching, and with the redesign uniform data format store, the single data platform of consolidation form is provided for each advanced application, the applicant makes every effort to by designing independently a multi-data source data cleansing and a data converted conversion service device, bear whole data acquisitions, conversion and integrated work, data acquisition and advanced application system are separated, to avoid the overlapping development of each advanced application system, reduce day regular data repeat import conserve system resources, reduce wrong probability, improve system stability.
