Problems solved by technology

The external interfaces provided by these databases are basically C APIs. The development of databases has helped people solve the transmission and storage of information, but new problems have emerged. Different data applications are used, and they cannot be transplanted to each other. , that is, the communication interface is not uniform, often requiring program developers to change a large number of codes, which brings great difficulties to program developers
In terms of security, there is also a new problem, that is, in the communication process between the application program and the database service, the data is transmitted in a clear way, which has a certain risk of information leakage

Embodiment Construction

[0006] In order to achieve the above-mentioned purpose, the present invention adopts a scheduling for large batch task processing of the database, which includes the following steps:

[0007] (1) Database service operation: run the database server;

[0008] (2) Run middleware: run applications;

[0009] (3) Connection communication: Determine whether the middleware is successfully connected to the database;

[0010] (4) Data reception: receive the request sent by the client, obtain the requested data, and encrypt the requested data;

[0011] (5) Data processing: and decrypt the data, construct SQL statements, open the data set, and take out the data;

[0012] (6) Write to the database: Write the extracted data into the database in turn;

[0013] (7) Return data: The database processing result is returned to the middleware, and the middleware encrypts the data and sends it to the client.

[0014] 1. In a scheduling step (1) for processing a large batch of tasks in a database as claimed in c...

Abstract

The invention relates to a scheduling method for large batch task processing of a database, belongs to the field of computer information processing, is a database middleware, and realizes data exchange between an application program and local or remote homogeneous or heterogeneous data sources. The invention provides a unified interface and shields the operational differences between databases. When the client sends a request for a certain database, the database middleware is used to search for a matching database connection, and data encryption is performed during the request process of the client. The database service completes the data query, and then returns the result to the client through the middleware terminal, through which the database is operated.

Description

Technical field [0001] The invention belongs to the technical field of computer information processing, and specifically relates to a scheduling method for processing a large batch of tasks in a database. Background technique [0002] With the rapid development of computer networks, the concept of traditional information systems has undergone tremendous changes. This information is prominently manifested in information storage, transmission, release, and access methods. Revolutionary changes have taken place. With the demand for high-performance technology applications The rapid development no longer meets the current needs of people. [0003] Currently, a variety of databases exist on the Internet, including Oracle Database Server, Microsoft SQL Server, Sybase, MySQL, DB2, etc. The external interfaces provided by these databases are basically C APIs. The development of databases has helped people solve the transfer and storage of information, but new problems have emerged. They c...
