Butler County Community College Course Coordinator: Roger Dunnell Business, Technology, and Workforce Development Division Fall 2000 COURSE OUTLINE Visual Basic Database Programming Course Description IN182. Visual Basic Database Programming. 3 hours credit. Prerequisite: IN108 Visual Basic Programming. This course provides students with the knowledge and skills necessary to create front end applications for data stores. The aim of this course is to give the student the background of accessing data and building interfaces to interact with a database. A variety of databases will be used in combination with Visual Basic. This course is designed for those anticipating a career in programming, or those seeking more knowledge in database programming. Required Textbook Connell, J. (1998). Beginning Visual Basic 6 Database Programming. Birmingham, UK: Wrox Press Ltd.
