You work as the database administrator for an IT training company named Domain.com. All servers on the Domain.com network run Windows Server 2003 and all database servers run SQL Server 2005. The Domain.com network contains a database server named Certkiller -DB01 B01. Certkiller -DB01 hosts a database named CK_Training that stores training data for the company. You are instructed to create checklists that lecturers can use to prepare training courses. You must use information from text files stored on Certkiller -DB01’s hard disk drive to create the checklists for the different certifications that Domain.com offers training for. You want to use Visual Studio .NET 2005 to build the checklists by implementing a common language runtime (CLR) function.
