In the application of the existing basic government information system, a large amount of basic account data and community element data generated in intelligent community construction, including house, personnel, people and room relations and the like exist, in the functional application, a large amount of fuzzy query application exists, and the following modes are adopted to complete data query at present:
1) data query based on relational database: the community element data is stored in a relational database, such as an Oracle database, a MySQL database and the like, or indexes are built on a plurality of key fields, or a plurality of key fields are combined and spliced into a field, and the index is built on the field, so that the fuzzy quick query effect of a certain degree is achieved;
2) data query based on NoSQL database: the community element data is stored in a NoSQL database, such as HBase and MongoDB, and the HBase database is taken as an example and stored in a column cluster mode, and a plurality of key fields are combined and spliced into a column of data to be stored together, so that the query access speed of the data is improved;
3) data query based on full-text retrieval technology: the community element data is converted into a data set formed by converting the key data field or the full field content into a processable information unit by using a full text retrieval technology. And the full text data can be edited and processed more deeply, such as words, characters, paragraphs and the like, so that the application can be quickly inquired and applied.
Comparing the three modes, wherein a data query method based on a relational database combines user authority data to form a fuzzy query method with authority, and the method has the problems that the search condition cannot be segmented and the query rate is low; the data query method based on the NoSQL database combines the user authority data to form a fuzzy query method with authority, and the method has the problem that the search condition cannot be divided into words; and finally, the data query method based on the full-text retrieval technology supports search condition word segmentation query but is difficult to support permission access.
