Abstract
The invention discloses a multi-database management system based on base table hash. Multi-database storage space is mapped to hash tables by the setting hash tables. High capacity space is managed efficiently and rapidly. An extensible database solution scheme is provided. The utilization efficiency of a database is improved.
Description
Technical field
The present invention relates to data-storage system, in particular it relates to a kind of multiple database management system based on storehouse table hash.
Background technology
At present, data base in information technology in occupation of consequence, high speed development along with information technology, data base is in routine work, business activity, even extremely important effect is all played in the life of people, in common server system, typically only include a single data base, convenient management and efficiency are higher, along with the geometrical progression of data volume increases, the capacity required of data base is the most increasing, but the requirement to management system is more and more higher therewith, in fact the centralized database capacity of present stage has been difficult to adapt to all kinds of demands, even if in order to adaption demand establishes the data base of a super large, its management system also can difficulty effectively manage, data access and maintenance difficulties are very big, efficiency is the lowest.
Summary of the invention
It is an object of the invention to, for the problems referred to above, propose a kind of multiple database server system based on storehouse table hash, to realize the advantage managing convenient easy extension.
For achieving the above object, the technical solution used in the present invention is:
A kind of multiple database management system based on storehouse table hash, including: some data bases, is coupled to the processing module of data base and is coupled to the database Hash table memory module of aforementioned processing module；
Database Hash table memory module is for storing the hash table of data element storage address in data base, this hash table creates when Database Systems are stored in data first, and follow-up data operate in synchronized update, in hash table, keyword stores address by mapping to point in multiple database, stores address and use Unified coding in these Database Systems.
Further, some data bases include following kind: pictorial information data base and Word message data base.
Technical scheme has the advantages that
Multiple data bases owing to including hash table, can be managed concentratedly, provide bigger autgmentability for single database system by the multiple database management system of various embodiments of the present invention, the most convenient.
Below by embodiment, technical scheme is described in further detail.
Detailed description of the invention
Hereinafter the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains the present invention, is not intended to limit the present invention.
The application of large-scale website complexity must use database server, and in the face of accessing in a large number when, data base there will be bottleneck, and a database server cannot meet application.Native system design applies data-base cluster and Ku Biao hash.Different module uses different design data patterns, according still further to certain strategy, certain page or function are carried out less database Hash, it is to avoid the bottle neck effect of data base.
Native system builds by the following technical solutions:
A kind of multiple database management system based on storehouse table hash, including: some data bases, is coupled to the processing module of data base and is coupled to the database Hash table memory module of aforementioned processing module；
Database Hash table memory module is for storing the hash table of data element storage address in data base, this hash table creates when Database Systems are stored in data first, and follow-up data operate in synchronized update, in hash table, keyword stores address by mapping to point in multiple database, stores address and use Unified coding in these Database Systems.
In common centralized database system, particularly in the case of data volume is little, the operating efficiencies such as access are the highest, along with the strategies such as data base increases, and Installed System Memory is often had too many difficulties to cope with, conventional virtual memory solve, native system uses hash table unified management multiple database, directly mapping address data memory, efficiency is higher, convenient management.There is multistage hash situation in hash table in should be noted that, presumable keyword key assignments points to multiple storage address by sequence table, the less situation in corresponding storage address in some keyword key assignments, selecting one hash function adapted with type of database is the step of hash table Technical comparing key.Database Systems read related data by this address.
Further, some data bases include following kind: pictorial information data base and Word message data base.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
Claims (2)
1. a multiple database management system based on storehouse table hash, it is characterised in that including: some data bases, be coupled to the processing module of data base and be coupled to the database Hash table memory module of aforementioned processing module；
Database Hash table memory module is for storing the hash table of data element storage address in data base, this hash table creates when Database Systems are stored in data first, and follow-up data operate in synchronized update, in hash table, keyword stores address by mapping to point in multiple database, stores address and use Unified coding in these Database Systems.
The most according to claim 1, it is characterised in that some data bases include following kind: pictorial information data base and Word message data base.
