Embodiment Construction

[0018] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0019] like figure 2 The schematic diagram of the remote data access method of the present invention is shown, which specifically includes the following steps:

[0020] Step 1. set up a database on the disk of the client, called the local cache database, the database is a collection of data items frequently accessed by the client, each data item in the database also includes two fields, one of which represents the Whether the data item is up-to-date, and another indicates the number of times the data item has been accessed. These two fields can be represented by enewStatus and AccessCount respectively. RenewStatus is true to indicate the latest status of the data item, false means it is not the latest status, AccessCount indicates the number of times the data item has been accessed, and AccessCount+1 is accessed each time the data item is accesse...

Abstract

The invention relates to the field of data transmission, and discloses an access method of remote data. The access method concretely comprises the following steps of: step 1, establishing one data base which is called as a local caching data base on a magnetic disk at a client side; step 2, connecting the client side to a server, inquiring the client side maintenance list of the client side in the data base of the server, and updating the local caching data base of the client side according to the content of the client side maintenance list; and step 3, when the client side needs to access one data item of the data base, firstly, inquiring the local caching data base, and then requesting the data item towards the server if the data item does not exist in the local caching data base. The active propelling is carried out by utilizing local caching and data updating; the access of most network data is localized; furthermore, the local data item is only updated when the local data item is necessary to be updated; the transmission times and the total transmission flow rate of the remote data are reduced; and the access efficiency of the data is improved.

Description

Technical field [0001] The present invention involves the field of data transmission, especially for a remote data access method. Background technique [0002] The traditional network database data access request is to connect to the server through the network through the client, then request a data, and then transmit the request data to the client.However, it is inevitable that the same client will request the same data items at different times, such as the second data of the server today and tomorrow. The traditional method is to repeatedly transmit the data through the network.Repeat the same data item is obviously a waste of resources and affecting efficiency.Its model is like an attachment figure 1 The schematic diagram of the traditional network database access process. [0003] For the access of the network database, whether the single database server or a distributed database server is used to build a database, regardless of the speed of the server's hardware, it cannot a...
