Embodiment

[0041] For a schematic structural diagram of the distributed database system of the embedded device in this embodiment, see figure 2 . The interface provided by the distributed database of the master main control card for the application module is described as interface A, which provides the application module with operation interface functions including creating tables, inserting, deleting, updating table items, querying, and table control; The interface provided by the distributed database of the line card or the standby main control card is described as interface C, which provides the application module with operation interface functions such as creating tables, inserting, deleting, and updating table items. The synchronization engine interface of the distributed database between boards is described as interface B. Among them, interface A and interface C undertake most of the data storage functions, and column handles are frequently used in this part. The following will ...

Abstract

The invention relates to a database technology, solves the problem of low efficiency of the conventional open source database system, and provides a data operation method for a distributed database in an embedded system and a board card. According to the technical scheme, the distributed database is operated by an application module according to multiple operation column handle modes adopted in the data operation method, and data can be stored. The board card consists of at least one application module and the distributed database, wherein each application module comprises a database table establishment request unit, a column handle establishment request unit and a database table operation request unit; and the distributed database comprises an interface unit, a column handle establishment unit and a database table index operation unit. The data operation method and the board card have the advantage of improving the system efficiency and being suitable for the distributed database.

Description

technical field [0001] The invention relates to database technology, in particular to the technology of distributed database in embedded equipment. Background technique [0002] Embedded devices generally include a main control card and a service line card. Among them, the main control card completes the control function, while the service line card completes the data forwarding function through a specific service interface. In order to improve reliability, the current embedded devices are generally equipped with dual main control cards, which are divided into active main control card and backup main control card; when the main main control card fails, the main Switch to the main control card, which is responsible for the operation of all control services. The active main control card, standby main control card and service line card are deployed in different slots of the embedded device. During the operation of the system, the configuration management information and routi...
