                     Web-based data warehousing systems have the advantages of ease of access, platform independence, and lower establishment cost but there are also challenges in implementing these systems. These challenges and proposed solutions include:
                     1. Scalability - Too many "hits" on a website can create slower transmission, lower performance, and increased server problems on the network. This can highly lower user satisfaction but can be improved by increasing server capability, ensuring server reliability, improving network bandwidth, and utilizin multiple mainframes with massive parallel processors (MPP).
                     2. Speed - The issue of speed can be dealt with high speed communcation lines, ISDN, cable modems, t1 and t3 lines, satelite networks and XDSL options. Also a caching technique is useful for data that is accessed from disks. For example, if someone requests data from a disk, the system checks disk cache first and if the data has been previously accessed, the system won't reaccess the data.
                      3. Security - There are two categories of security that need to be dealt with: unauthorized attempts to access private data via internal and external communication networks and computer viruses. The problems can be dealt with by applying user level security, not making extremely sensitive data available through the internet, and by using methods such as enscryption, secure protocol, and public/private key protocol;
                      Basically, in my search for the best data management system, I will take into considerations scalability, speed, and security, as well as look for some of the methods suggested in the systems I will analyze and assess .
