I spend a large amount of time translating software requirements into schema and queries. I want to talk about UI design choices that lead to data access patterns that are awkward to implement using SQL Server. The query for this example might use syntax like this: ORDER BY LastModifiedTime OFFSET @N ROWS. Sort By Column.

As part of good design, we should consider the effects of changing all of these variables.
