Virtualization and paging

In enterprise applications, we have to deal with data in different formats and sizes. We need to find ways to display and collect this data in the most user-friendly and performance-efficient way. Nobody likes an application that has all the beautiful controls and features but that takes a lot of time to run basic operations. So, performance and responsiveness are an implicit requirement for enterprise applications. I'd argue that it makes more sense to make it an explicit requirement, so that it can be properly planned for and managed.

Virtualization and paging are common techniques that are used when we need to deal with more data than it makes sense to load into memory at one time. With data virtualization and data paging techniques, we load just the data from the repository that is currently displayed on the screen, and we dynamically load more data as needed. Based on the idea of spatial locality of reference, we could also load some extra data to create a fast...
