How does this relate to Application Modernisation? If an organisation has many legacy databases (e.g. Access, Excel), then this platform can be utilised to centralise these disparate legacy databases. The crux here, is that due to xRM being a platform and not an application, it has the structure to provide for multiple entity relationship constructs and is not limited to being a replacement for one database application.
Typical uses for database based applications to be modernised onto xRM can include : Equipment Registers & Tracking; Process Automation; Asset Management; Manage Field Work Orders; Recurring Services Contract; Offline Quote and Order Management; Case Management; Warehouse Management; Complaints & Issues Management; Quality Feedback; Help-Desk with sophisticated routing; Licence Management; Training Systems and Grants Management.
xRM naturally integrates well with other Microsoft products but also has out-of-the-box connectors to integrate with other vendor or bespoke products. This is useful in modernisation cases where an application is being modernised, but which as part of its functionality still requires some data to be sourced from other systems.
