Salesforce can be integrated with the online engagement system which is used for activating their constituents for petition drives and events. The user can also use the wealth screening service for prospect management and to store that information in Raiser's Edge. Raisers Edge is hosted on the IT infrastructure and also requires you to maintain a large server system and provide the services and the support associated with that hosting. Salesforce is hosted in cloud, on Salesforceӳ distributed and secure servers. You can read this blog for the Raisers Edge Salesforce Integration.
