On the basis of technique scheme; Further; In above-mentioned steps 103; Memory controller can also the control data memory storage application layer from the basic data of basal layer, extract the general combined data of using; And the application layer that memory controller can also the control data memory storage is extracted the Data Mart data of using from the basic data of basal layer.Particularly; The application layer of data storage device can be subdivided into two parts; That is: general gather the part and the Data Mart part; The detailed process of step 103 comprises: the first step, the application layer of memory controller controls data storage device general gather part and from the basic data of the intermediate data in middle layer and basal layer, extract the general combined data of using and store at least one application summary information table into; In second step, the Data Mart of the application layer of memory controller controls data storage device part is extracted the Data Mart data of using and is stored at least one application data fairground table into from the basic data of the intermediate data in above-mentioned application summary information table, middle layer and basal layer.Wherein, In the first step; The general part that gathers is preferentially extracted required general combined data from the intermediate data in middle layer, if the intermediate data in middle layer can't satisfy the needs of general combined data, the general part that gathers is extracted from the basic data of basal layer again.In second step; The Data Mart part is preferentially extracted required Data Mart data from the intermediate data in general summary information table and middle layer; If the intermediate data in general summary information table and middle layer all can't satisfy the needs of Data Mart data, the Data Mart part is extracted from the basic data of basal layer again.This step has increased the dirigibility of data storage through the data from middle layer and basal layer co-extracted application layer.
Below respectively through instantiation, under the control of memory controller, the storing process of basal layer, middle layer, application layer describes in detail.
Basal layer
In above-mentioned steps 101; Under the control of memory controller, during the basal layer of data storage device storage basic data, for the storage of agreement theme; Adopt following processing mode: at first, memory controller controls protocol information table is stored at least a protocol number and protocol type code; Then, memory controller controls is as the protocol number and the protocol type code of at least one type information table storage corresponding types of the sublist of protocol information table; At last, memory controller controls is as the data of the corresponding agreement of at least one data table stores of the sublist of type information table.
Below introduce the storage means of basal layer under the control of memory controller that the present invention proposes through a specific embodiment.Basal layer has been contained the basic data of operation system; For example, basal layer can comprise the data of following system: core system, individual loan system, to public risk system, Net silver system, fund system, three-party deposit system, billing system, international clearing system, foreign-currency trade system, credit card system, large-amount payment system, small amount payment system etc.In the date storage method that the present invention proposes,, the data storage of basal layer is classified according to agreement corresponding service characteristics and service logic according to the inquiry and the frequency of utilization of business demand and data.Agreement is the contractual relation of signing to certain specific products or service between financial institution and the client, and the data content of an agreement can comprise: the declaration form of deposit at bank account, loan account, inner account, loan receipt, contract, insurance company etc.With the source operation system is example, and table 1 is the tables of data of variety of protocol in the operation system of source.Referring to table 1, this source operation system includes but not limited to the agreement of record in the table 1, and is concrete, in the data content such as table 1 of each agreement.
Table 1 is the tables of data of variety of protocol in the operation system of source
In embodiments of the present invention, to above-mentioned variety of protocol, according to the difference of business characteristic, above-mentioned agreement is classified, according to the data of each agreement of classification and storage.For example, in the variety of protocol of table 1 record: savings account agreement, loan account agreement and inner account agreement all belong to the account quasi-protocol; Personal loan receipt agreement and to the equal data receipt of public affairs loans receipt agreement quasi-protocol.In the form of basal layer storage, comprise protocol information table, type information table and tables of data, wherein, the protocol information table is as super parent table, at least one type information table of protocol information table subordinate, the type information table is as the sublist of protocol information table.The type information table is as parent table, at least one tables of data of type information table subordinate, and tables of data is as the sublist of type information table.Wherein, the protocol information table is stored at least a protocol number and protocol type code.The protocol number and the protocol type code of type information table storage corresponding types.Variety of protocol according to table 1 record; The type information table can be divided into account category information table and receipt category information table; The protocol number of storage accounts quasi-protocol and protocol type code in the account category information table, the protocol number and the protocol type code of storage receipt quasi-protocol in the receipt category information table.The data of the corresponding agreement of data table stores.According to the variety of protocol of table 1 record, account category information table subordinate's tables of data can comprise savings account tables of data, loan account tables of data and inner account data table or the like.Receipt class contract information table subordinate's tables of data can comprise personal loan receipt tables of data, to public affairs loans receipt tables of data or the like.Wherein, each data table stores related data of corresponding protocols separately.With the savings account tables of data is example, and the protocol number of storage savings account agreement in the savings account tables of data, protocol type code, mechanism number, protocol status code, Currency Type, agreement Start Date, agreement date of expiry, interest rate, subject code, paper money converge data such as sign, the balance of deposits, last financial transaction day and customer manager.Further, for the agreement of inconvenience classification, agreements such as the card of record and contract in the table 1 for example, card tables of data that it is corresponding and contract dataset table can be directly as the sublist of protocol information table.
A kind of preferred implementation is, in practical application, above-mentioned as super parent table protocol information table table and all be logical table as the type information table of parent table, reality is physicsization not.
In technique scheme; When the basic data of storage basal layer, through agreement being classified the data qualification storage corresponding according to business characteristic to different agreement; Thereby obtain desired data rapidly and accurately according to classification when being convenient to reading of data, improved data access efficiency.
In above-mentioned steps 101; Under the control of memory controller; When the basal layer of data storage device is stored basic data; Storage for the attribute history lists; Adopt following processing mode: memory controller controls attribute history lists is according to protocol type, the attribute information of at least one agreement of classification and storage.Through the attributive classification of different agreement type is deposited, only relate to the corresponding attribute history lists of this agreement to the accessing operation of the data of a certain quasi-protocol.Do not distinguish protocol type with existing basal layer and the attribute history lists that each protocol attribute all directly stores the agreement master meter into concentrated compare, the method for the above-mentioned classification and storage protocol attribute of the embodiment of the invention can significantly improve the efficient of user capture location in the data access process.
The middle layer
In the date storage method of the embodiment of the invention, between basal layer and application layer, increased the middle layer.
In practical application; Utilize the data of basal layer storage; Actual business requirement realizes multiple application; For example, can include but not limited to following application: client's single view, customer relation management, profitability analysis, client's integration managing, retail customer handle examination, financial general ledger form etc.The data that these application relate to all derive from the basic data of basal layer storage, and need handle basic data according to the real needs of using.For example; Client's single view application need extracts remaining sum, month average daily remaining sum, the season average daily remaining sum and data such as year average daily remaining sum of client's essential information, all kinds of savings account, card and every loan receipt from basic data, and data such as the loans and deposits remaining sum of client's level and all kinds of average daily remaining sums.The customer relation management application need extracts the client from basic data essential information, the situation of holding of client's various product, client trading preference such as gathers at data.Client's integration managing application need extracts data such as the gathering of all kinds of accounts and loan balance, classification of business transaction, client's essential information from basic data.The retail customer handles data such as the examination application need extracts every client of customer manager exploitation or lifting from basic data assets, debt, intermediary service information.Finance general ledger form application need from basic data, extract each section now the account balance data and gather so that general ledger and ledger are consistent.
According to the analysis of desired data is used in above-mentioned application and other, in embodiments of the present invention, before application layer was extracted data, elder generation carried out preliminary extraction in the middle layer to basic data and gathers.On this basis, application layer is directly used the data of extracting in above-mentioned middle layer and perhaps again the data of middle layer extraction is aggregated into the more data of coarseness such as client's level, subject level and mechanism's level.
Particularly; In above-mentioned steps 102, middle summary information table can comprise a kind of or several combination arbitrarily in following each table: account levels summary information table, voucher summary information table, receipt summary information table, customer deposit summary information table and customer lending summary information table.Correspondingly; Under the control of memory controller; When the middle layer of data storage device is extracted the corresponding intermediate data of at least one application and is stored centre summary information table into from the basic data of basal layer; Adopt a kind of or several combination arbitrarily in the following processing mode: the first, the memory controller controls middle layer is extracted the corresponding data of account levels summary information and is stored account levels summary information table into from the basic data of basal layer; The second, the memory controller controls middle layer is extracted the corresponding data of voucher level summary information and is stored voucher summary information table into from the basic data of basal layer; The 3rd, the memory controller controls middle layer is extracted the corresponding data of receipt level summary information and is stored receipt summary information table into from the basic data of basal layer; The 4th, the memory controller controls middle layer is extracted the corresponding data of customer deposit level summary information and is stored customer deposit summary information table into from the basic data of basal layer; The 5th, the memory controller controls middle layer is extracted the corresponding data of customer lending level summary information and is stored customer lending summary information table into from the basic data of basal layer.
From the basic data of basal layer, extract the corresponding data instance of account levels summary information with the middle layer, the mean data of attribute, remaining sum and each frequency of account level is extracted in the middle layer from basal layer.Storage means with variety of protocol shown in the above-mentioned table 1 and above-mentioned basal layer is an example; Real needs according to various application; Under the control of memory controller; Middle layer extraction from basal layer needs the basic data of book keeping operation; That is, the base layer data that subject code and professional code name are arranged is extracted in the middle layer from basal layer.For example, adopt in the data of basal layer storage of said method the middle layer data in account data table, loan account tables of data and the inner account data table of from basal layer, drawing deposits.
In the middle layer after basal layer extracts data, with above-mentioned data storage in middle summary information table.Particularly, in above-mentioned steps 102, under the control of memory controller, the middle layer of data storage device during to middle summary information table, is adopted following processing mode with intermediate data storage:
The first, the major key of tables of data of basal layer that adopt to add prefix is as the major key of middle summary information table, or, adopt the major key of the tables of data of basal layer form with preset supplemental field in the middle of the major key of summary information table.
According to the data of required extraction, if each major key still has uniqueness when being arranged on the major key in the tables of data of required a plurality of basal layers in the form, then can be with the major key of the major key in the tables of data of basal layer as middle summary information table.Otherwise, if exist when being arranged on the major key in the tables of data of required a plurality of basal layers in the form major key not have the situation of uniqueness, then can adopt any one mode in the following dual mode be provided with in the middle of the major key of summary information table.Mode one: before the major key of the tables of data of each basal layer, add different prefixs and distinguish, with the major key of the tables of data of the basal layer that adds prefix major key as middle summary information table.Mode two: the major key of middle summary information table adopts the combination major key; With the major key of the tables of data of basal layer a part as this combination major key; And increase the field that another one is used to distinguish the tables of data major key of basal layer again; As middle summary information table supplemental field, by the major key of the tables of data of basal layer and supplemental field combination combination major key as middle summary information table.Mode two does not change the record of former table major key, has not only helped quick and precisely searching but also can improve related efficient between the table of middle layer and basal layer.
The second, according to the type of the general character field in the tables of data of at least one basal layer, the type of this general character field of summary information table in the middle of confirming.The type of the general character field in the tables of data of at least one basal layer not simultaneously, the type of this general character field of middle summary information table is a variable type.
In middle summary information table, when the type of general character field is set, need consider the type of this field of tables of data of each basal layer simultaneously, the expansion needs of other data source that further also need look to the future.For example, the type of certain general character field in first tables of data of basal layer is 4 character types, is designated as CHAR (4); Type in second tables of data of basal layer is 5 character types, is designated as CHAR (5); Type in the 3rd tables of data of basal layer is 6 character types; Be designated as CHAR (6); Then can the type of this general character field in middle summary information table be set to 6 bit variable character types; Be designated as VARCHAR (6); Further, it is also conceivable that the needs of the data source that following other business is required, the length of this field is expanded; The type of this general character field in middle summary information table is set to 8 bit variable character types, is designated as VARCHAR (8).Adopt aforesaid way that the type of the general character field in the middle summary information table is set, can guarantee the data of from the tables of data of basal layer, extracting are accurately stored, and can save storage space.Further, through field length is expanded, improved the extensibility of the middle summary information table in middle layer.
The 3rd, the combination of Currency Type field and value type code field of tables of data of adopting basal layer is as the major key of middle summary information table, with the data-switching of different Currency Types in the tables of data of basal layer for specifying Currency Type and storing middle summary information table into.
In the basic data of basal layer storage, the Currency Type that different accounts adopts possibly have nothing in common with each other.Because can't directly carry out computing to different Currency Types in application layer; Therefore the situation to different Currency Types gathers in the middle layer, thus make application layer can be only mode through simple summation can obtain fine-grained summarized results such as client's level, subject level, mechanism's level according to account.In the middle summary information table in middle layer, adopt Currency Type field and the combination of value type code field in the tables of data of basal layer, as the part of the major key of middle summary information table.In the middle layer, with the data-switching of different Currency Types in the tables of data of basal layer for specify Currency Type and store in the middle of the summary information table.For example, the data-switching of the remaining sum generic attribute stored in the base layer data table to Renminbi and/or dollar corresponding data, in middle summary information table, is stored respectively the data of former coin, folding Renminbi and folding dollar.In the middle layer Currency Type and corresponding data are converted, provide convenience, saved the time that application layer is extracted data, improved data access efficiency thereby extract combined data for application layer.
The 4th, calculate the data of the attribute of deriving and store middle summary information table into according to basic data.
Concrete needs according to the various application of application layer calculate the required attribute of deriving that calculates according to base layer data of each application layer in the middle layer.For example; From the remaining sum history lists of basal layer storage, extract balance data on the same day; And according to the concrete business rule of using; According to the same day balance data calculate to obtain the data of the attribute correspondences of deriving such as nearly three months average daily data of equal data of the monthly data of remaining sum, remaining sum season, the average annual data of remaining sum, remaining sum, nearly 1 year average daily data of remaining sum, with the data storage of above-mentioned derive attribute and correspondence in middle summary information table.When application layer need be extracted above-mentioned derivative data; Needn't extract and calculate the basic data of basal layer; The data that only need extract the required attribute correspondence of deriving from the middle layer get final product, thereby have improved the speed of application layer reading of data, have improved data access efficiency.
The 5th, the intermediate data in middle summary information table storage preset time period.
Need the data of basal layer be gathered in the middle layer, and the data that require the middle layer to gather can support the real needs of the multiple application of application layer, therefore, need the intermediate data in the storage preset time period in the middle summary information table in middle layer.If this preset time period is long, can waste storage space, if this preset time period is too short, then can't satisfy the real needs that application layer is all used.A kind of preferred implementation is, this time cycle is preset as 13 months, promptly keeps the data at nearest 13 months the end of month in the middle summary information table in middle layer.And, on this basis, can also adjust the preset time cycle according to the concrete condition of using.
Particularly; The method that adopt said extracted in the middle layer, gathers and store intermediate data; Can store multiple middle summary information table in the middle layer, specifically can include but not limited to following each table: account levels summary information table, card summary information table, other voucher summary information table, receipt summary information table, customer deposit summary information table and customer lending summary information table.
