Problems solved by technology

Among the existing relational database products, Microsoft SQLServer, IBM DB2 and Oracle all provide certain automatic design functions of physical databases. However, the automatic design functions in these database products are closely bound to the special functions provided by the database, so It cannot be applied to other relational databases, including widely used MySQL, PostgreSQL, and the domestic Oscar database

Embodiment Construction

[0037] like figure 1 As shown, the automatic design method of the physical database of the relational database is jointly completed by two processes of load information, database schema information and statistical information mining process and candidate physical property generation and optimal physical property combination search process. figure 2 and image 3 The specific details of these two processes are explained respectively.

[0038] like figure 2 Shown, the relational database system load of the present invention and statistical information mining method comprise:

[0039] Step 10) Collect relevant statistical information such as the number and execution time of various query (SELECT), update (UPDATE), insert (INSERT), delete (DELETE) SQL statements per unit time; this type of collection is completed in two ways , for the relational database system whose source code cannot be obtained, the proxy method is used to intercept and extract the SQL statement information...

Abstract

The invention discloses a method for automatically designing physical database based on SQL load digging, comprising two flows of digging load information, database mode information and statistic information and combined-searching candidate and optimum physical characteristics. It makes frame and algorithm completely independent of physical characteristic library and introduces automatic design into different relation database products or adds physical characteristics and optimization solutions to the existing relation database products, not changing integral frames and internal algorithms but only modifying the physical characteristic libraries.

Description

technical field [0001] The invention relates to an automatic design method for a physical database (PDB) applicable to a general relational database, in particular to an automatic design method for a physical database in a general relational database based on SQL load mining, and belongs to the technical field of databases. Background technique [0002] In database technology, the relational model database has the characteristics of simple and flexible data structure, easy to learn and understand, and has a solid mathematical foundation, and has now become the standard of the database. The database software widely used at present is a relational database management system based on the relational model. [0003] In database design work, logical database design and physical database design are the core links. Logical database design is to design the global logical structure of the database and the local logical structure of each user according to the user's requirements and t...
