Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] Structured Query Language SQL (Structured Query Language) is an advanced, widely used non-procedural programming language, whether it is Oracle, Sybase, Informix, SQL Server and other large database systems, or Visual Foxpro, PowerBuilder, etc. commonly used on PCs All database development systems support the SQL language as a query language. The invention also supports the SQL language, which allows more users to use CigQL more easily without changing the original habit of using the database.

Abstract

The invention discloses an implementation method for a database language technology based on a unified standard of data. The method comprises the steps that extraction is performed on source data according to different data types through a data extraction module, and the data obtained after extraction is stored in a CigQL database according to an FIFO mode; the data obtained after extraction is transformed according to logic, arithmetic and data properties through a data transformation module, and Hash table data and metadata obtained after transformation are stored in an Index region and a Metadata region respectively; the data stored in the Index region and the Metadata region are encapsulated according to a CigQL protocol through a data encapsulation module to form the data in the unified standard; and the data in the unified standard is exported according to usage categories through a data export module, and the exported data is stored in a Data Switch region so that a back end can call the data. Through the implementation method for the database language technology based on the unified standard of the data, the data is transformed to be in the unified standard, and therefore the problem that heterogeneous data is difficult to fuse is solved.

Description

technical field [0001] The present invention relates to the field of computer information technology, in particular to an implementation method based on database language technology for realizing unified data standards. Background technique [0002] With the advent of the information age, databases are developing towards complexity and diversification. Since the formats and standards of various databases are not uniform, the structure and data file format of each database are incompatible with other databases, and the databases used by each customer have unique characteristics. Data representation, each application corresponds to a different database. [0003] In the prior art, although incompatible databases can be connected under certain circumstances through some special software or tools, the workload is huge and consumes considerable time and energy. [0004] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0005] The t...
