微机汉字大地测量数据库系统的设计

The Design of MC-GDB System

    摘要
  • 摘要: 本文论述了利用IBM-PC/XT微型机和CdBASE-Ⅲ关系型DBMS,建立微机汉字大地测量数据库MC-GDB(Micro-computer Chinese Geodetic Data Base)系统的方法。系统采用了分块存贮和有效的数据压缩方法,实现了大规模数据的微机管理。最后,简述了检索、统计、报表等使用方式。针对大地测量数据的特点,还讨论了有关平差和绘图方面的功能。

     

    Abstract: This poper discusses the design for MC-GDB(Micro-computer chinese Geodetic Data Base) system using IBM-PC/XT personal computer and relational DBMS CdBASE-Ⅲ.By using the methods of storing in blocks and efficient data condensation,large-scale geodetic data management can be realized through personal computers.Finally,some application modes,such as retrieval,statistics and tabulation,are briefly described.The adjustment and drawing functions are also discussed with reference to the characteristics of geoderic data.
