Design of E-learning platform by SQL

This paper proposes a database-based E-learning system, which is targeted at the problems existed in the current teaching, combines the network teaching mainstream model and the latest theoretical achievements at home and abroad, as well as uses the current more mature network technology. The system discusses in detail the system requirements and features from the network teaching system design goals, user characteristics and operating circumstances. And it also uses B/S multi-tier architecture to analyze and design the network teaching system, and eventually to propose a new type of network teaching system solution.
