Problems solved by technology

[0004] The existing parallel database technology lacks understanding of the diversity of business requirements, lacks the flexibility to support business configuration, and especially cannot break through the limit on the number of database branches (sub-tables), which makes it difficult to use and promote parallel databases

Embodiment Construction

[0012] The present invention uses but not limited to the following technical means:

[0013] The realization of the parallel database management system has the following steps:

[0014] 1 When MultiDao is obtained through template generation or running through meta-mode, the system registers VirtualDao to MultiDao, and any VirtualTable corresponds to and only corresponds to one VirtualDao. VirtualDao can also be automatically generated through templates or meta patterns. ,

[0015] 2. The system configures the one-to-one correspondence between VirtualTable and PhysicalTable by using but not limited to database or configuration file.

[0016] 3. The application calls MultiDao and uses a selection method to map to the subtable and operate VirtualDao on the subtable.

[0017] 4. The system transforms the VirtualDao operation into the actual PhysicalDao operation on the physical database through the corresponding relationship configured in step 2.

[0018] 5. If it is an updat...

Abstract

The invention provides a parallel database management system and a design scheme. Four operation modes including branch selection, branch union, branch competition and branch synchronization are included. Sub-table execution units and sub-tables are generated and found through a main table execution unit according to a mapping method; finally, virtual sub-table operation is converted into operation of physical tables, and return results are collected. Compared with an existing parallel database, the parallel database management system and the design scheme have the advantages that isomerous databases are integrated and run, the number of branches can be dynamically increased and decreased, branch operation modes are comprehensive, and the number of branches, namely, sub-tables, is free of upper limit. Thus, parallel computing can be rapidly configured by an engine user, and the requirements for user backup, system integration, high-performance computing and the like are met.

Description

technical field [0001] The invention relates to the field of computer software development, and is applied to system integration, distributed database, high-performance computing and the like. Specifically, the design scheme encapsulates specific Dao through VirtualDao to form a consistent operation on a single table; through MultiDao to manipulate multiple VirtualDao in parallel, realize the flexible operation of multi-table and multi-database; declare the selection method of branches in MultiDao, And the generation and search methods of ID and virtual table name, so as to provide effective support for parallel computing. Background technique [0002] Parallel database is the product of the combination of database technology and parallel computing, and it is a database system with parallel computing capabilities. [0003] Parallel database processes database tasks in parallel through multiple nodes, thereby improving the performance and availability of the database system....
