VISTA Blood Bank Software Version 5.2 Software Requirements Specifications

Introduction
The Software Requirement Specifications (SRS) provide detailed information regarding the functionality of the software. These requirements are based on the intended uses detailed in Appendix F and the Safety Critical Requirements detailed in Appendix G. A variety of tools are available for use in meeting these specifications. In general, the data dictionary for specific files provides a great deal of control through the data type, pattern matches, and input transform requirements. However, specific algorithms have been included in the software routines where appropriate and Kernel Security and Menu Management provides additional tools (i.e., menu access and security keys for meeting the specifications). As with the file structure and the rest of the documentation, the Software Requirement Specifications are divided into one general (G) and three major categories, donor (D), inventory (I) and patient (P). The numbering system used indicates which category is assigned to that particular specification (e.g., SRS#G1) is the first in the general category. In order to assist in cross-referencing material and minimizing duplication whenever possible, the information in the column labeled “Functionality” roughly corresponds to the Safety Critical Requirements in Appendix G and the options. However, the term “general” has been used for those SRS which apply to more than one functionality. In addition, the Safety Critical Requirements do not include those SRS that relate only to the generation of administrative and management reports.

Description
Requires both an access code and a totally encrypted verify code that must be changed every 90 days in order to access computer system. Requires assignment of specific menu options and specific security keys in order to access/enter donor data. Utilizes an automatic time-out algorithm and site specified time-out parameters to prevent potentially inappropriate access, in the event that an authorized user were to breach the usual security measures and leaves the CRT unattended while still signed on. Provides on-line documentation and help prompts based on the data dictionaries for the files used by the donor menu options/routines. Provides detailed data dictionaries for each file which provide all of the specific details, including name and number of the field, the global location, the type of data, etc. Additional details are provided in Appendix F that includes a detailed description of the data elements for the various files as part of the Intended...
