Embodiment Construction

[0056] The specific implementation of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0057]In view of the problems existing in the prior art, the present invention proposes a comprehensive retrieval scheme for structured data and unstructured data, shielding the difference between back-end data sources, as long as the user enters keywords, the system will automatically check the data in the data source. The data is retrieved, and the result of the highlight processing is finally displayed to the user. Especially for querying structured data from a database, the present invention adopts a query adapter method. Traditional database queries are all based on SQL statements or based on specific database client software. When the query source is multiple different databases, users need ...

Abstract

The invention discloses a method for synthetically searching structurized data and non-structurized data, which comprises the following steps: a database for storing the structurized data is enlarged, different types of documents with the non-structurized data are processed in a filtering manner, the corresponding interface processing types are realized according to the document suffixes, the corresponding configuration is finished, the type of document is analyzed, and the index is established, so that the inquiry of the type of document is realized; and the searching of the database and the documents is performed according to key words, and the searching results are displayed. By adopting the method, whatever the searching source is an ordinary database for storing the structurized data or an FTP for storing the non-structurized documents, the searching results can be intuitively and accurately revealed to users.

Description

Technical field [0001] The invention relates to the field of data retrieval, in particular to a method for comprehensive retrieval of structured data and unstructured data. Background technique [0002] Data types can be roughly divided into two types, one is data that can be represented by the same hierarchical structure, that is, structured data, which is usually stored in the database in the form of data tables; the other is in Txt text, Word text , Pdf text and other forms are stored in FTP (File Transfer Protocol, file transfer protocol), unstructured data that cannot be represented by a unified structure. [0003] Because these two types of data are very different in nature, they have always been stored and managed separately, and each has its own method of operation. SQL statements are generally used to retrieve structured data from databases, while index retrieval is used to retrieve unstructured data. However, no matter which retrieval method is adopted, the retrieval re...
