地质调查数字成果数据管理的方法技术实现

Technology Realization of Data Management for Digital Products

结合江苏省地质调查研究院的数字成果数据情况 ,讨论了数字成果数据管理的方法技术实现问题。采用MSSQLServer作为数字成果数据的数据库管理系统 ;采用VB开发工具 ,结合GIS技术开发客户端软件 ,即利用VB提供的ADOField对象的GetChunk和AppendChunk方法来存取MSSQLServer中的图形数据 ,并通过GIS技术对图件进行管理和再现。

Based on the digital products of the Geological Survey of Jiangsu Province, the problems on the realization of data management for digital products are discussed in the text. MS SQL Server is adopted as the databank management system for the digital products; by using VB developing tool, and combining GIS technology, the client end software is developed, that is, by using GetChunk and AppendChunk, objected by ADO Field and provided by VB, the data of graphics in MS SQL Server is accessed and their management and reproduction are conducted through GIS technology.
