China Banknote Credit Card Factory can provide customers with the input service of credit card application forms. The work includes scanning the application form and original materials, inputting the application form information, checking the input information and exporting the database file.
Data entry personnel shall enter according to the paper application letter, and at the same time, they shall attach a scanned copy of the original. Each application letter is 6 pages of A4 paper, and the total scanned file is about 300K, so the data of each user is about 350K. China Banknote Credit Card Factory uses B/S architecture LAN environment application program for data entry, which can not only reduce the maintenance work of the client, but also lose to the C/S architecture system in performance, which can reduce the maintenance workload of the administrator and improve the scalability of the system.
The system adopts B/S three-tier architecture design, deploys application server and database server, and the foreground client uses browser to access the system. The whole workflow is: first, scan the credit card application letter with a high-speed scanner. The scanned data file is in jpg format and stored in the file system of the server according to the specification. The customer ID number is used as the identification of the customer file. Then, each input computer inputs data by opening the scanned image file and stores it in the database. Finally, the checking computer checks the data according to the input information. After the inspection is completed, the status of the data becomes the official warehousing data. When a batch of data is input and checked, the data is backed up by tape drives and submitted to commercial banks.
The presentation layer is the interface display of the actual user. As long as the client has an operating system, network protocol software and a browser, it can carry out application operations, and users can obtain and edit data and information from the network through the browser.
The application layer includes Web server and application server, which can be installed on one physical server or deployed on different physical servers. The Web server is responsible for processing HTML, accepting user requests and returning static pages to users. Web server organizes information into distributed hypertext, describes and organizes information through Hypertext Markup Language (HTML) and Hypertext Transfer Protocol (HTTP), and simply and practically realizes hypertext/hypermedia data access with the whole network space as the operating background.
The application server is responsible for processing the application logic and dynamically accessing the database through the data interface. If a user requests a static page, it will be returned by the Web server. If the user's request is a dynamic page such as information query, it will be processed by the application server, and the processing result will be returned to the Web server, which will return the processed page to the user.
The database server is responsible for data storage and management; The database is connected with the business database system through the database interface, so that the data in the business database can be published to the information system database conveniently, regardless of the system platform and type of the business database.
In order to improve the efficiency of data entry, the process of scanning first, then entering and finally checking is adopted.
A. data scanning
The original data are scanned by Kodak's high-speed scanner. The scanned files are single files, in groups of 7, including 6 pages of application letter information and a signed picture information. They are stored in the hard disk of the file server of * * * according to the customer ID, so that each input client can transfer to this machine for input. According to the customer bank's requirements for the security of the original written materials, the card factory can complete the scanning and storage work in the controlled area agreed by the customer bank, and the original documents will be managed by a special person. The integrity of the original data will be checked before the work, and the original data will be counted and sealed immediately after the work is interrupted to ensure that the original data will not be leaked.
B. data entry
The operator must log in to the system and confirm his legal identity before he can open the input interface to input data according to the scanned document and store the input data in the background server. Cannot export unchecked data. Each input data is accompanied by information about the operator and the input time.
C. data validation
Inspectors also need to log in to the system first. After confirming the legal identity, you can open the verification interface for data verification, and the verified data can be exported. Each inspection data is accompanied by information about the inspector and the inspection time. The inspection method is a combination of manual re-entry and inspection. For key fields, the re-entry method is adopted, and the two inputs are the same, which is regarded as correct. If they are different, they must be checked. In this way, mismatched information such as spaces can be detected. The way to check is to check whether the contents of the field are consistent with the original. If they are consistent, they are considered correct, but this method can't detect inconsistencies, such as spaces and special characters.
D. background database export interface
The background database will be exported as a file in XML format, because XML is the most commonly used data file format at present. Specific XML tag definition rules are described in the DTD file.

The background database will be exported as a file in XML format, because XML is the most commonly used data file format at present. Specific XML tag definition rules are described in the DTD file. The system architecture is shown in the following figure:
Database export chart
The specific process is as follows:
A) formulate the data specification of XML, that is, DTD (or Schema) file;
B) Use the tools provided by the data exchange platform to define the data source to be extracted, including database name, table name, field name, etc.
The data exchange platform will automatically extract data from the specified data source, and then output the XML file according to the pre-established XML data specification format.
The data files of commercial banks will also use XML files, and it is necessary to formulate a DTD (or Schema) file to standardize the format of this data file. The system framework is as follows:
Data import map of commercial banks
The specific process is as follows:
A) Formulating the XML format of data submitted by commercial banks, namely DTD (or Schema) files;
B) Commercial banks make XML data files according to the specified data format.
After the commercial bank submits the data file to the China Banknote Credit Card Factory, the data exchange platform parses the XML file according to the specified XML data format and inserts it into the corresponding database table.
