Embodiment
Referring to accompanying drawing 1, the present invention includes the two large divisions: the information integrated platform of real time data and based on the data sharing platform of integrated platform links by software bus between two platform subsystems; Wherein, described information integrated platform comprises: source database, adapter, object library, filing program, data warehouse, Task Distribution and load balance module, described source database can be text library, concern the storehouse, storehouse in real time, at different databases, adapter relation of inclusion type database conventional data integrated adapter, text type data adapter unit, real time data adapter; Described data sharing platform comprises: the source data administration module, and unified control of authority module, form and other business modules can be developed as required, conveniently are integrated in the system by software bus.
During system works, the source data administration module is accepted user's instruction, the configuration of configuration real time data source and the measuring point that needs to gather, the object library configuration of the configuration of adapter and adapter correspondence, archive information disposes a series of information, Task Distribution and load balance module are according to the configuration information in the source data administration module, the initialization execution environment, generate each task, and distribute suitable data for each task and visit adapter and object library, relevant database conventional data integrated adapter and text type data adapter unit directly store the data that collect into data warehouse by software bus according to the instruction of described Task Distribution and load balance module, the data that the real time data adapter is gathered are then under the instruction of Task Distribution and load balance module, at first deposit object library in, the filing program is depositing data warehouse later in to the real time data processing in the object library.
The relational data that described relevant database conventional data integrated adapter is handled can be types such as ORACLE, SQLSERVER, Access, DB2, SYSBASE.
The scheme that the arrangements module can dispose in the described relationship type adapter comprises three classes, be respectively: general purpose single table mapping scheme, general multilist mapping scheme and independent mapping scheme, the user can selection scheme type, the performance period of scheme, platform can be according to the title of field, coupling source table and the intersegmental mapping relations of purpose literary name also can be configured the artificially.
Described general purpose single table mapping scheme comprises full dose more new model, incremental mode, main thin table schema.
Described full dose more new model is that the data integral body in the source data table is moved to the purpose table, be mainly used in the renewal of static list of data, by critical field " comparison one by one ", if primary key value exists in the purpose table, then upgrade the analog value of purpose table corresponding record, otherwise insert record.Full dose pattern customized expression is as follows:
Total＝{key＝#，Condition＝#；#}
Wherein " # " represent acquiescence that situation is not set; The create-rule of the major key ID of the corresponding purpose table of key, such as can set a sequence name key=seq_salt at oracle database, condition is the data screening condition of source table, is used for " comparison one by one ", by "; " separate a plurality of conditions can be set, such as Condition=name; Age, wherein two condition fields of name and age representative source table.
Described incremental mode promptly guarantees to need only in the meantime without any change in the last data of once having transmitted, and will be left in the basket when transmitting next time, because the isomerism of data source, current technology is difficult to realize that general incremental data extracts.Characteristics at electric network data, the present invention by the increment identifier field compare one by one mode realize, described increment identifier field is that timestamp field or ID increase field or any field with incremental nature certainly, if the data source table does not contain the field with incremental nature, then adopt the mode of critical field " comparison one by one " to realize data migtation, described critical field is the field that is combined into major key, ignore this record if primary key value has existed in the purpose table, otherwise insert new record.The incremental mode expression formula is as follows:
Incremental＝{key＝#，Condition＝#；#，Inc＝#}
" Inc " is used for identifying delta field in the formula, such as " Inc=YMD ", represents " YMD " time field as the increment identifier field; After task was finished, the currency that system will write down " YMD " field generated the sq1 statement when subtask is carried out down.Such as " select*from saltreal where YMD＞2009-02-2608:30:20 ", wherein " 2009-02-2608:30:20 " is exactly the value of " YMD " field of system log (SYSLOG).
Described master carefully shows migration model, and in the performance history of database application system, often with outer yard data consistency that guarantees between reference entity, this have the table of reference relation to be called main thin table.Main thin table schema can guarantee the integrality of data, consistance, and availability is avoided the generation of " dirty " data, has very high Practical significance.Main thin table schema expression formula is as follows:
Main-sub＝{Key＝#，Inc＝#，condition＝#；#
MT＝#，SF＝#:#；#:#，RF＝#:#}
The MT correspondence be master meter name (static information table); The mapping relations of corresponding source literary name section of SF and master meter field; The mapping relations of corresponding master meter field of RF and thin literary name section; Carry out to thin table in the data migtation implementation will according to SF the inquiry master meter is set, and query results is mapped in the thin table according to being provided with of RF.
Referring to accompanying drawing 2, as above shown in the legend: " MT=TOWERLEANINFOR, SF=line number: LINE; Sim:PHONE, RF=ID:PRIMARY_ID, Key=seq_email.nextval, Inc=time, condition=TIME; " TOWERLEANINFOR is the master meter name; Line number: LINE represents the line number field of source table and the LINE field correspondence of dynamic table; ID:PRIMARY_ID represents that static table ID and dynamic table PID's is corresponding; Seq_email.nextval is the sequence in the purpose table database; TIME is the condition field of purpose table, judges whether these data import; " time " is source table delta field.
Described general multilist mapping scheme is to an expansion of general purpose single table task for the application performance that improves system, the multilist scheme is close and prescription case of the less demanding some tasks compositions of real-time with update frequency, and the thread of each task sharing in the prescription case is carried out in proper order.
Described independent mapping scheme is meant that the user can write independently program for still undefined certain type data migtation and synchronous task in the system, and it is broken into the jar bag carries out for system call.
Described object library is distributed database, preserves the data of handling through the real time data adapter, and the application system and the filing program that offer the upper strata are used.Object library is designed to distributed database, and the real-time of response service system requires and file the filing request of program fast.
Referring to accompanying drawing 3, object library logically is distributed database, and it physically can be that one or several Database Systems constitute, and can dynamically adjust and distribute the target database of each adapter correspondence by metadata management.Its objective is and satisfy the high real-time requirement of application system, and prevent under the network failure situation directly the storage data warehouse and cause losing of historical data, real time data is carried out " keeping in " real time data.Object library is stored the operation of power networks real time data (the concrete time is configured by metadata) in 5 minutes usually, removes immediately after the data filing program disposes its processing, and data retrieval has very high response speed.
The Basic Information Table of described data warehouse storage measuring point essential information adopts static table structured data table, and so-called static table is meant the geostationary tables of data of content in tables of data and list structure, the table.In the real-time data memory design, describe and write down the essential information of each monitoring point with static table.Described Basic Information Table can be divided into Measeure table and MeasureClass table two class.The Measure table record essential information of measuring point: the title of measuring point, the coding of measuring point, measuring point classification, the bound of measuring point value, unit and data precision, the measuring point value is to the Table I D and the Field ID of usefulness.The MeasureClass table is sorted out all kinds of measuring points of system.
The record data of described data warehouse storage measuring point adopt at least one horizontal vertical list structured data table, each of tables of data is listed as a corresponding measuring point, stores the record data of this measuring point, and each row storage of tables of data is the data of the measuring point of all row correspondences sometime.Usually the list structure that adopted of real-time power network data management system is vertical list structure, i.e. corresponding measuring point of each row, the information of a measuring point of a recording storage.Do not have history data store situation under, adopting the vertical table structure is easily, but in the real time data application system of attaching most importance to history data store, adopt the vertical table structure that data storage, data are used, especially data mining brings difficulty.And, under this memory module of the present invention, eliminated data redundancy, database storing utilization of space height.
Before the storage measuring point data, table number of being stored by described metadata management block configuration measuring point data and row number.
Described filing program is filed the real time data in the purpose storehouse according to horizontal vertical list structure rule, deposit data warehouse in, for data mining provides safeguard.The filing task can be carried out and automatically perform by hand, and that realizes data duplicates batch processing, Timing Processing automatically.
In the described unified control of authority module a plurality of roles are set, the function that each role is corresponding certain, each user can have one or more role, all functions that sub-role succession father role has.
In the affiliated unified control of authority module IP access list is set also, is used for disposing IP that allows visit and the IP that allows the access portion function,, then no longer should occur in the table if certain IP does not allow to visit; Perhaps network segment of configuration can be visited earlier, and then forbids the IP that wherein some needs are forbidden; All IP only occur and allow in this table and could visit, and certain functional identity is under an embargo if certain IP appears in this table, and then this function can't be visited; IP access list is as shown in table 1:
