The invention discloses a data compression quick retrieval file system and a method thereof. The system comprises a data generation system, a request connection processing system, a data inquiring system, a permission management system, a data recovery system and a data physical system, wherein, the data generation system is used for compressing data files defined by other systems or table data in other-type databases to generate a compression data file, and simultaneously generates a system index file and a data structure information file; the request connection processing system is used for establishing connection with client sides; the data inquiring system is used for collecting client sides, for analyzing specific inquiring words, for analyzing the data structure information file and an index file, for retrieving a data file and for returning the retrieved data; the permission management system is used for establishing users and distributing user permission; the data recovery system is used for recovering the designated data files into other-type databases or data files defined by other systems; and the data physical system comprises the data structure information file, a data retrieval index file and a data file.
Description
technical field [0001] The invention belongs to the field of data retrieval systems. In particular, it involves application systems that require data compression and support fast query. Background technique [0002] In the field of data retrieval systems, the current common practice is to implement data retrieval technology based on common database technology. In the common database mode, since the database uses specific data files after packaging, the outside world cannot directly compress its data. For example, if multiple table data are stored in the same database, the outside world cannot directly analyze the table data. At the same time, the efficiency of data query is due to the data Functions such as modification and transaction processing, as well as the impact of massive data currently stored cannot guarantee fast query speed. [0003] With the rapid development of society and economy, social production and consumption activities are growing rapidly, and the amoun...
