data base data model
2.OPTI system (Optimizing System of Network Data Model Structure) constructs for a data base designer a network data model which satisfys some requirements for a set of objective variables by employing a man-machine interactive and heuristic process with interactive successive refinement, and produces automatically the DDL and DMCL source programs, which describes the model.
5.In the article proposed the weather forecast CBR model, has studied the disaster weather case base establishment method, withdraws the case base use by the data mining way compared with the manul establishment case base the good and bad points, proposed the data model and extracts the case the algorithm;
6.Aimed at solving all kinds of disadvantages of raster graphic data management in GIS software, hierarchically both structure and implementation project of the raster graphic database are studied in this dissertation. The data base engine model design and image processing form main part of the dissertation. The main point lies in the management of a great lot raster data and service for processing raster data rapidly and accurately.
7.On the basis of the analysis and research on the frames of some current decision support systems,the concept of the frame of synthetic decision support system(SDSS) is drawn into this paper,which integrates data warehouse(DW),data mining(DM),on-line analytical processing(OLAP),data base(DB),model base(MB) and knowledge base(KB).
9.S-57 is a standard specialized in digital chart data transmission. The paper introduces the data model and structure of S-57 issued by IHO, gives the pivotal contents and main characteristics of S-57 standard, creates the database according with IHO S-57 standard and supporting S-52 display, and achieves reading and writing of standard S-57 data. The work establishes a good base to construct the electric charting display and information system (ECDIS).
10.Abstract: By analyzed the structure of multi-media teaching software for computer software technique foundation,this paper presented a abstract model,and introduced a learning process control algorithm based on reasoning.We discussed and realized data base management and multi-media fields of data base list structure.In the end,this paper analyzed the software running statue.
