Abstract

The invention relates to the technical field of bidding / tendering, and provides a data OLAP analysis and matched retrieval-based intelligent bidding / tendering method. The method comprises the following steps of: 1, constructing a bidding / tendering data warehouse by kettle; 2, constructing an OLAP-based analysis model; and 3, retrieving the bidding / tendering data warehouse according to the analysismodel. The method has the beneficial effects that bidding / tendering, the data warehouse and an OLAP technology are combined, so that the cost of star connection in concurrent OLAP is reduced, the concurrent query processing ability is improved and the efficiency is improved; the on-demand query, on-demand analysis, on-demand display and on-demand distribution of data analysis results are realized, so that bidding / tendering purchase demands are optimized; and bidding / tendering history data is converted into theme-oriented, integrated and stable data sets which change along with time, and the data sets are used for supporting the management decision process, so that the visualization of data warehouse management is realized on the macro level.

Description

technical field [0001] The invention relates to the technical field of bidding, in particular to an intelligent bidding method based on data OLAP analysis and supporting retrieval. Background technique [0002] Bidding refers to the act of the buyer publicly inviting the seller to make an offer according to the transaction conditions issued in advance notice or published; bidding refers to the act of the seller being invited to make an offer according to the bidding conditions. Tendering and bidding is a way to optimize the procurement of projects, goods and services by means of competition in accordance with the principles of openness, justice and fairness under the conditions of a market economy. [0003] In the bidding process, a large amount of data needs to be processed; traditional bidding has many human factors, low efficiency, and poor traceability. [0004] Today, data processing can be roughly divided into two categories: on-line transaction processing (OLTP for s...
