【摘要】 ArcSDE是空间数据库引擎,允许用户用关系数据库管理系统(RDBMS)存储和管理空间数据。设计并实现了基于.NET平台的ArcSDE矢量数据访问的C++类库。这些类按托管和非托管两层进行设计,数据访问功能由非托管类调用ArcSDECAPI实现,托管类对外公开非托管类的功能,可被任何.NET兼容的程序设计语言调用。更多还原

【Abstract】 ArcSDE is a tool that allows you to store and manage spatial data in your chosen Relation DataBase Management System (RDBMS). ArcSDE geometry data access class library of C++ based on Microsoft .NET platform is designed and r ealized. Classes are consisted of two tiers: managed tier and unmanaged tier. Th e unmanaged classes invoke ArcSDE C API to realize its function. The managed classes as an interface between the unmanaged classes and the outside application can be invoked by any type of programming language which is compatible with .NET framework.更多还原
