Graduate School selects Salesforce as graduate records management solution
The Graduate School has announced that its next-generation graduate records management solution will be built on the Salesforce platform, replacing the existing GradDB and Graduate School database systems.
The decision comes after an extensive assessment period and stems from the Graduate School’s commitment to modernize and streamline operations while ensuring effectiveness in managing graduate records. The move to Salesforce is expected to provide a more robust and cohesive solution that will better serve the needs of Purdue’s academic community.
The project’s initial phase is underway and will focus on replacing GradDB, which is used by the College of Engineering and some College of Science programs on the West Lafayette campus, with a targeted launch date in October 2024. The Graduate School’s database, which is utilized systemwide by faculty, staff and graduate students on all of Purdue’s campuses, will follow with an expected completion in July 2025.
A dedicated web page has been established to share project-related information and updates. Communications will also be sent out to those directly impacted via their Purdue email accounts and periodic updates will be included in Purdue Today.
Questions related to the database migrations can be sent to Nicole Moody, [email protected] , for the Graduate School or Janet Beagle, [email protected] , for GradDB.
