Geological Survey Of Anhui Nest North Regional Fill Figure Internship Database Research And Development

Database is a technology that developed from the 1960s, which is an effective tool to save, manage and output data. It's widely used in many fields.In 1980s, database came into use in the geological researches and brought about an advance. But the geological database is still at developing stage in China. A large number of geological data need to be arrayed and put into databases. However, this is inconvenient not only for preservation but also for inquiry and search. So it is necessary to set up a series of databases.Chaobei area is located in the Northeast range of Yangtze plate and east of Tan-Lu fault zone. After a long period of geological evolvement, the stratum in this area forms complex structure, which is primarily E-W and NNE superposition. Chaobei area developed most stratums and the attitude of stratums are placid. Folds, faults, cleavages are developed in this area that provide a good field for regional geological survey and geological mapping.Chaobei area worked as the field practice base for regional geological survey and geological mapping since 1950s. Until now, there are more than 30 colleges and universities to set up regional geological survey base here. Chaobei area has been a new field practice base for the sophomores of the department of geology of Northwest University since 2003. After many years' researches, We have accumulated abundant resources, but the traditional texts and pictures on paper can not meet the demand of the application of technology in education and reform in geological education and can not appeal to the students as well. Hence, it is necessary to set up a database with vivid texts and pictures, which is also the purpose of the paper.According the characteristic of regional structure and stratum, we adopt Access 2000 as the operation system of database, the popular visual programming soft—Visual Basic 6.0 and the operate function of structure query language—SQL as the developing tools to develop the database management system of Chaobei area regional geological survey and geological mapping. The system primarily includes four modules: data input module, data maintenance module, data query module and data output one. It is convenient for users to append, modify and delete data for further research. The database includes fourteen tables that are stratum, structure, fossil, regional geological survey methods and fields records. And the friendly intuitionistic interface can make the user master the principle of the system in a short time.
