Method for storing and searching data in mobile device embedded Linux, and mobile device for storing and searching data using it

摘要

Disclosed are a data storage and retrieval method for a portable terminal equipped with embedded Linux, and a portable terminal for storing and retrieving data using the method. The portable terminal includes a data collecting unit for collecting file information from at least one of a database, an internal file system, and an external file system; A data storage unit for storing the collected file information, wherein the file information collected from the internal file system or the external file system is synchronized with the previously stored file information; And a data retrieval unit for retrieving desired data from the data storage unit, wherein data collection from the data collection unit, data transmission, data storage in the data storage unit, and data retrieval in the data retrieval unit are provided by embedded Linux. It is performed by concurrency control using IPC. According to the data storage and retrieval method of a portable terminal equipped with an embedded Linux according to the present invention and a portable terminal using the same, various methods of collecting file information from a database, an internal file system, and an external file system installed on an embedded Linux in the portable terminal are provided. By simultaneously storing and indexing data delivered from two collection units, you can shorten the collection time and search in the middle of the collection, so you can quickly search for the data you want during data collection.
