Q: What is the difference between MIDAS and Microsoft's Remote Data Services (RDS)?
A: RDS functionality was modeled after MIDAS resulting in some similarities between the two. However, MIDAS provides many features not found in RDS. RDS was designed only to be a web-based client for data access and can't be used for stand-alone applications, where as MIDAS is browser independent. RDS also dictates the use of Internet Explorer 4. MIDAS provides data constraints, data aware controls, support for heterogeneous networks, master-detail support, robust conflict resolution, and support for business rules on the middle tier, all of which can not be found in RDS. These MIDAS features allow you to be more responsive to your changing business needs. Develop robust, flexible, rapidly evolving thin client multi-tier applications with a minimum of time and code.
我现在使用KBM的中间层,发现一点比较不好的是
中间层查询数据后,需要有一个转存的过程,这个过程是在中间层完成的,当数据量上6万的时候有点慢,如果直接传RECORDSET则很快,
这时候发现ADO有RDS,这个好像更快,在DELPHI里面也有个简单的例子
但不知道性能如何,如果现在转为使用RDS则工作量比较大,
有没有朋友有相关的经验阿?
