应用于电网调度自动化系统的实时数据库的设计与实现 Searching records through creating index through foreign key.3.Searching records through creating cycle list.Through these three ways to searching records,the performance is very good. In order to convenience to design application,the system provides four kinds of access interfaces.1.Common realtime database access interface.2.Quick realtime database access interface.3.SQL language access interface.4.Object-oriented realtime database access interface.Selecting right access interface can improve the performance of the realtime database management system KEY WORDS:electric power network dispatching automation system realtime database table set field group subfield object-oriented database access interface 第3页共4页应用于电网调度自动化系统的实时数据库的设计与实现 Searching records through creating index through foreign key．3．Searching records through creating cycle list．Through these three ways to searching records，the performance is very good． In order to convenience to design application，the system provides four kinds of access interfaces．1．Common realtime database access interface．2．Quick realtime database access interface．3．SQL language access interface．4．Object．oriented realtime database access interface．Selecting right access interface Can improve the performance of the realtime database management system． KEY WORDS：electric power network dispatching automation system realtime database table set field group subfield object-oriented database access interface 第3页共64页
