Component Technology for Analyzing Grain Burning Area
DU Hong-xing · Ordnance Industry Automation · 2005
The component-based software for analyzing burning area of grain was developed with COM (Component Object Model) technology, and it was designed with three layers architecture. User interface is customized in alternating layer, the request of user is processed and internal connection is implemented in interface layer. And in main program, the system integration is realized through transferring graphics component, grain component, data processing etc. Interface defined by IDL and attribute method was adopted for grain component, after compiled, interface code was added to create component. For graphics component, the graphics backstop was drawn with OpenGL function, and the data from account was processed by data processing component. SQL was used as database to access data.
