Method for implementing class memory database access and retrieval

Abstract

This invention relates to memory database access and index method, which comprises the following steps: establishing relative data joints memory list according to the needs; establishing relative index list that is the data structure based on balance two-branch tree mode with dynamic distribution order; distributing the string priority memory list of the index list and scanning and analyzing several inquires given; distributing the property inquires priority orders to determine the distributing rules.

Description

technical field [0001] The invention relates to a method for accessing and retrieving, in particular to realizing fast data accessing and retrieving under the premise of low resource occupation for memory-like databases. Background technique [0002] With the rapid development of computer and network information technology, the use of computers and networks has become more and more inseparable from existing office and life. Various large amounts of information and data are run through the network or stand-alone, realizing data sharing and remote transmission. While managing the data in the database, methods and software for effectively classifying and accessing data and implementing advanced retrieval are also produced and applied accordingly. [0003] At present, the data management methods that are widely used include hierarchical, network and relational databases. Although the problems of data access and retrieval can be solved to a certain extent, there are still certai...

AI Technical Summary

Problems solved by technology

[0003] At present, the data management methods that are widely used include hierarchical, network and relational databases. Although the problems of data access and retrieval can be solved to a certain extent, there are still certain defects in the establishment and application of such commercial databases.

For example, the cost of database establishment and use is high, which is too expensive for small data management units; in addition, existing databases such as MS SQL, DBII, and Oracle are all based on hard disk or tape operations. Unable to meet the requirements of real-time response, fast access and retrieval

Now there is also a mode of data access and retrieval using in-memory databases. Although the retrieval speed is fast, it also takes up a large amount of external storage and internal memory resources, especially for embedded systems.

[0004] As mentioned above, the existing various database access and retrieval methods have obvious shortcomings and deficiencies for small data application units, and there is no corresponding solution in the disclosed technology
