Abstract

The invention discloses a row and line mixed database storage method, which comprises the steps of: creating a table and physical storage spaces corresponding to the table, and determining the corresponding relationship between lines and the physical storage spaces according to application requirements; inserting records into the table, and grouping according to the corresponding relationship between the lines and the physical storage spaces; and writing recorded line values as rows into the corresponding physical storage spaces. By means of the row and line mixed database storage method provided by the invention, whole-table inquiry is avoided effectively, I / O (Input / Output) expenditure is reduced, and the speed of data reading and the inquiry performance of a full-text database are increased.

Description

technical field [0001] The invention relates to a technology for storing data in a database, in particular to an application-oriented mixed row-column storage method for storing massive unstructured data objects. Background technique [0002] At present, the data managed by the database management system is presented in the form of a two-dimensional table of rows and columns, where rows correspond to records, and columns correspond to fields of records. [0003] When traditional row-based databases store data, the data value of a row is written into memory or hard disk as a one-dimensional string. Therefore, if you want to query a field value of a record, you need to read the entire record. But for query-intensive applications, most queries often only use a part of the field values ​​of the records. The use of row storage technology will cause the system to have the following deficiencies in data reading and storage, and the performance cannot meet the needs of applications...
