AD05 A problem many pharmaceutical companies have is making its clinical trial information easily accessible to authorized non-SAS users. This situation can be greatly compounded when this information exists on multiple platforms and legacy systems. The autho rs describe an n-tier application which allows the user to access and analyze clinical trial information. The front-end tier is a web browser providing users a single interface. Access to information is controlled such that each user receives a different list of available information depending on security privileges. The back-end tiers decide how available information should be accessed, and then retrieves the requested information using a variety of applications (ASP, SAS/Intrnet, Perl, etc.). In addit ion, programmers can publish their own SAS programs/web applications to the user community. |
