Research on LabSQL Database Technology in the Virtual Laboratory Design

Aiming to improve the efficiency of access to remote database in the virtual laboratory design, the paper analyzes features and shortness of the LabView to have access to remote database and elaborates methods and programming model for LabSQL to implement database access and proposes the integrated application strategy of the LabSQL toolkit and ADO technology. Combined with a network virtual laboratory’s application development, the paper provides access steps based on LabSQL database and virtual laboratory’s design process and it is proved that the program is easy to implement and easy to use.

The Application and Implementation of ADO Technology in Industrial Management System Based on MFC

With the rapid development of computer network, automation and electronic commerce, more and more industrial production are in urgent need of the convenient and efficient integration of production and management system to adapt to the change and solve the condition of the onerous task, low efficiency, high cost, personnel tension. This article focuses on a typical industrial management system which is based on C/S architecture and uses MFC application framework. And it introduces ADO technology as the middle bridge which is used by the client to access databases. What is important is that the dynamic link library is used in the system to help ADO access database. The ADO technology has the characteristics of easily-using, high speed, low memory expenditure and less disk space, which optimize the system, make the system realize the high performance, high compatible data access.
