The effect of each functional module:
Task scheduling modules
Task scheduling modules gathers a series of conversion operations becomes a data sequence of operation, and in sequence, increases necessary checking and log record, and this data manipulation sequence is referred to as task.Task scheduling modules can be confirmed each task executions plan by the task executions time and the frequency that in operation system, dispose.
The ETL engine modules
ETL is meant and from origin system, extracts data, and the form of translation data to a standard loads data into the process of target data memory block.According to the difference of transmission means, the ETL engine is divided into Web service data pick-up engine, file data extraction engine, middle database data pick-up engine etc., and supports further expansion.
The ETL engine modules is to different data transfer modes; Carry out the configuration operation and the data relationship mapping of drag operation and the various data sources of easy configuration operation completion through visual configuration interface, and the ETL process prescription can save as the XML file format of international standard.
Concurrent processing device module
The different types of data extraction process of different pieces of information source or same data source is described to independently conversion operations.The concurrent processing device can be used as independently thread execution with each conversion operations, makes the ETL extraction process concurrently to carry out, and improves the execution efficient of data pick-up.
The load equalizer module
The dynamic feedback of load equalization algorithm is used in the load balancing design.This algorithm is considered the real-time load and the response condition of server, constantly adjusts the ratio of the request of handling between server, at the parallel effective load pressure between each server of balance of load balancing when carrying out date interworkmg, effectively promotes collecting efficiency.
Interface adapter
Interface adapter is made up of data mapper and communication mode transducer.According to the difference of transmission means, interface adapter is divided into Web service interface adapter, file interface adapter, middle database interface adapter etc., and supports further expansion.Interface adapter has been accomplished the conversion from database to the standard traffic stipulations object that meets the CIM model, and the data based interface definition that will convert formats processing, enables to transmit through its corresponding interface mode
SSL encrypts and authentication (SSL unit)
As technological realization means, comprehensive authentication of design one cover and encrypted transmission scheme are with assurance data source access security and data transmission security with authentication and SSL encrypted transmission technology.Through technological with the realization of communication protocol binding; SSL can carry out the function expansion synchronously with extraction engine; And support also for the extraction engine of same type of host-host protocol whether configuration need carry out the authenticated encryption transmission, thereby guarantee to mate the external data interface adapter.
Regulation engine
Regulation engine is developed by inference engine; It is a kind of assembly that is embedded in the application program; Realized operational decision making is separated from application code, and used predefined semantic module to write operational decision making, accepted the data input; Explain business rule, and make operational decision making according to business rule.Regulation engine is that task scheduling modules, ETL engine, concurrent processing device and load equalizer provide rule support.In processes such as task scheduling process, data pick-up, corresponding functional module is obtained rule support from regulation engine, and carries out work according to the rule that regulation engine provides.Regulation engine can be according to the regulation rule of configuration or analysis Data Dynamic.
The exception monitoring engine
Exception monitoring engine each link in whole data pick-up process is monitored the data quality, and when the data exception behavior takes place to writing down unusually, analyze and handling.The exception monitoring engine realizes that content comprises: the completeness check of data comprises the verification of incomplete record and the verification of data item vacancy; Check uploads whether code type data item meets the unified standard coding requirement in the data; Check data corresponding relation and statistical summaries add and the logic soundness verification that concerns etc.
The invention has the beneficial effects as follows: adopt Web Service mode, accomplish real-time and require, and can accomplish the bigger data passes of data volume than higher data interaction and business cooperation; Enterprise SOA can insert third party's service easily, and the third party system just can be linked on the service bus as long as the corresponding bundled components of exploitation is deployed in the system, can also realize the plug and play of third party system at native system.
