ODBC, OLE, ADO, and ASP Questions and Answers
The technologies ODBC, OLE, ADO, and ASP are essential in connecting databases with applications, making them common in programming questions and answers for interviews and placements. ODBC (Open Database Connectivity) and ADO (ActiveX Data Objects) provide data access interfaces, while ASP (Active Server Pages) helps in creating dynamic web pages. These concepts are frequently asked in technical rounds of Microsoft, TCS, and Tech Mahindra. Practicing C programming MCQ and Java MCQ related to these technologies will strengthen your knowledge of database connectivity and web integration. Understanding these will help you write efficient, scalable, and database-driven applications across platforms.
