Data-hungry packages are solutions that require absorption of data into themselves in order to function. In some cases they may even require that they become the "master" for that data. Once the data is owned by the package, that software becomes the only way to update, change or access the data. The data-hungry package might solve a particular business problem such as ERP. However, inventory or finance "data demands" placed upon an organization will often require complex integration and changes to systems that lie well outside of the original scope.
