Under the requirement of a leading USA continuing education company in Virginia, US , SDIT has assisted to develop an Online Course Delivery System for it. The company wanted its entire education process online, so as to serve the customers better and faster. Finally it hired SDIT to develop their existed Online Course Delivery System. It consisted of course content administration, user record management as well as advertising and reporting functions. By using the CGI/Perl/PostgreSQL to J2EE (JMS, EJB, JDBC, JavaMail) technology, SDIT has assisted the company to switch from the existed Online Course Delivery System to a more advanced Online Course Delivery System, so that it could meet the demand of the fast-growing number of the users. The new system turned out to be able to deliver a more reliable and responsive solution. It enabled the E-business of this company more convenient, for which we received the recognition of the company. You can look at the illustration as follows.
