Comparing Solutions

Client-Server based applications, those that require that software be installed on both the server and the user workstation, was as an outgrowth of the mainframe 3270 market in the 80s. Mainframe systems in the 70s and 80s supported the entire application at the mainframe. The user display had no memory and therefore no capacity to accomplish other tasks. With the introduction of the PC into mainstream corporate environments in the late 80s and early 90s, Client-Server applications were able to provide more power and functionality and, off-load some overhead from the mainframe.

Throughout the 90s, software manufacturers developed robust applications built on the Client-Server architecture. More powerful databases from Oracle, IBM, and Microsoft increased the capabilities of these programs. Unfortunately, the cost to clients for infrastructure and licensing such products rose as well. Software manufacturers charged for the base license cost plus a charge for software that was installed on each workstation. Expensive dedicated line costs were incurred to connect remote or even across the street facilities. Backup and disaster recovery procedures added another level of cost. Maintenance and support became a serious issue for manufacturer and user alike with systems having to be taken "down" for maintenance, upgrades, or other changes.

To reduce costs and provide similar or increased functionality, corporations like Citrix introduced controlled Thin-Client technology. Many direct and side benefits came from this technology. However, with the unfolding of the Internet and its use in developing business processes in the late 90s, a new world was born. It is the world of Web-Based Thin Client applications.

Web-Enabled Solutions

In the rush to develop products that deliver features through a simple browser interface, many Client-Server based software companies added browser front ends to their products, making their software "Web enabled." Their solutions have some web functionality, but are still based on client-server technology, not Web technology. These solutions require that software be installed on each user's workstation. Of substantial importance to the end user customer, Client -Server applications are licensed for each client and the server. It results in a more costly acquisition and a more problem prone maintenace issue. Web-enabling a Client-Server based application is an attempt to keep alive an old technology that is lacking

Web-Based Thin Client Solutions

Emerald Systems Inc. builds true Web-Based Thin Client applications that utilize the Web as part of their platforms. With these solutions, customers do not need to distribute software to all workstations. Workstations may access the application through a browser such as Microsoft Internet Explorer 6.0. The application runs over the Internet or secure Intra-net. Web-Based THin Client applications are less costly to license and are easier to manage than their client-server based counterparts. In addition, they are easier to maintain and upgrade. The application does not need to be brought "down" in order to be updated or provide maintenance. Of key importance, should the customer's network go down, Emerald can provide on-line disaster management capabilities in less than one hour to maintain a fully functional corrections management process.
