Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0039] The embodiment of the invention discloses a database access device, system and method to reduce system busyness or downtime caused by a large number of or malicious accesses on the basis of realizing access to the database.

[0040] see figure 1 , a database access device 100 provided by an embodiment of the present invention includes:

[0041] The interface module 101 is used to receive the access request and the target policy sent by the business logic, c...

Abstract

The invention discloses a data access device which comprises an interface module, a strategy application module and a database access module. The interface module is used for receiving access requests and target strategy sent from business logic, calling the strategy application module to acquire execution result of the access request, and calling the database access module to access a database according to the execution result. The strategy application module is used for collecting real-time monitored index data, determining the execution result of the access request according to the real-time monitored index data and the target strategy, and sending the execution result to the interface module. The database access module is used for accessing the database according to calling condition of the interface module. According to the technical scheme, the execution result corresponds to the access request so that access to the database is controlled, and system busy or downtime caused by a great quality of access or malicious access is avoided. The invention further discloses a database access system and a database access method which have the same technical effect as the database access device.

Description

technical field [0001] The present invention relates to the technical field of database access, and more specifically, to a database access device, system and method. Background technique [0002] At present, the connection and operation of the client program to the database is generally realized by the driver program that implements the database protocol. The client program can easily add, delete, modify and check the database by calling the database driver interface. When the number of user visits increases, a large number of database connections will be generated. If the connection reaches the upper limit of the database connection, the client will wait. If the connection is still not connected within a certain period of time, the client will timeout. Although large concurrency can be resolved by increasing machine performance, separating reads and writes from the database, adding multiple database instances, and using memory caching, etc., the system may still be busy o...
