![]() Prognos System Requirements
PureSafety's Prognos software is a 32-bit, ODBC compliant client/server application for managing safety, workers' compensation and disability information.
The client component uses Microsoft Visual C++ and the server component is supported by Microsoft SQL Server database software.
Prognos communicates with its databases using the Open Database Connectivity standard (ODBC). The ODBC standard allows easy access to data for creating supplemental reports and queries using a wide variety of off-the-shelf report writers and data tools. Prognos uses the Crystal Reports run-time report engine for internal reporting. All reports are stored within the database for easy management. Prognos is available with a Report Maintenance Utility for importing and managing custom reports within the Prognos database. The Prognos security system controls access to electronic medical records and other sensitive information by creating User IDs and Passwords for authorized users. The security system provides the capability to create screen level, function level (insert, update, read-only, and delete), company level, and report level access definitions. Screen level security controls access to individual dialog boxes. Function level security controls what a user can do once a particular dialog box is displayed. Company level security controls access to claim information by company or work site. Report level security controls access to individual reports. Prognos is a 32-bit application that operates on Windows 95 or later workstations. The following is a list of the minimum and optimal workstation requirements.

Network Server Requirements:
Microsoft SQL Server 2000 operates on Windows NT or later network servers, requires 100 megabytes to install, and a minimum of 64 megabytes RAM to operate. TCP/IP is the recommended network protocol. Actual disk storage and RAM required is dependent on the number of users requiring access and the number of records processed

Wide Area Network (WAN) Configurations
Traditional WAN configurations involve implementing the Prognos database software on a central server to store data and Prognos client software on individual workstations. Workstations are configured to record and retrieve information from the Prognos database server via the WAN. Prognos also supports "thin client" environments using Citrix and Terminal Server. Citrix/Terminal Server implementations are server-based configurations that maintain the Prognos client and server components on a central server(s) and provide Prognos user access through the Internet. The advantages of implementing Prognos in a Citrix-based environment include decreasing implementation costs, reducing bandwidth required to achieve acceptable performance levels, and decreasing ongoing support and maintenance costs. Implementing Prognos in a WAN configuration requires a supporting communications infrastructure. We recommended a MINIMUM bandwidth of 128KB for traditional WAN based implementations and 56KB for Citrix/Terminal Server based implementations. In addition, it is important to consider that Prognos client performance in this environment can be adversely affected by non-Prognos-related data transmissions on the WAN and by packet-level priority assignments. All Prognos databases support Microsoft's Open Database Connectivity (ODBC) standard. If requested, PureSafety will provide a database schema to customers interested in developing independent data access tools for use within their organization. |
