Embodiment Construction

[0019] Preferred embodiments of the present invention are described in detail below.

[0020] As shown in Figure 4, the present invention provides a kind of distributed access method based on embedded database, comprises the following steps:

[0021] A1. The embedded database creates a unified access interface function, an interface proxy module, and an interface service module, wherein the interface proxy module sets an interface access control block for recording interface and application identification information. Wherein, the unified access interface function of the database is implemented differently on the server side than on the client side; on the server side, the interface provided by the embedded database is directly invoked to access the database, and on the client side, the synchronization mechanism provided by the operating system is used. Data acquisition and message interaction are handed over to the database interface proxy module and the interface service mod...

Abstract

The invention provides a database based on the embedded distributed Access methods, including steps: A1. Visit to the creation of a unified interface function, Acting interface modules, interface modules services; A2. Server through a unified database access interface function calls Interface function access to data; A3. client function call interface unified access to the database interface agent module sent requests for visits, a synchronous operation targets simultaneously, blocking the client applications; A4. agent interface module received requests for visits to the service interface modules send requests, transmission parameters; A5. service interface module receipt of the request, called unified access to data access interface functions to the interface module sent agents respond to news and data transmission; A6. Interface Acting module response to information received, copied to the data received unified access interface function in the output buffer, the corresponding targets simultaneously available for purchase, and continue to obstruction of the implementation of the client application.

Description

technical field [0001] The invention relates to the field of embedded databases, in particular to a distributed access method based on embedded databases. Background technique [0002] Embedded systems generally refer to the integration of operating systems and functional software into computer hardware systems, which have the characteristics of small software codes, high automation, and fast response speed, and are especially suitable for systems that require real-time and multi-tasking. As various embedded operating systems are widely used in aviation, aerospace, communications, military, industrial control, medical equipment and other fields, the application of embedded databases is also increasing. Some fields have raised the demand for distributed access to embedded databases, so there is a distributed embedded database including an extensible data management system (E-DBMS) as shown in Figure 1 and Figure 2. C / S) architecture application. [0003] Distributed Softwar...
