In most cases, swollen glands return to normal size after the illness or infection has passed. But here are some things to watch for: Glands that swelled up very suddenly; Glands that are much larger than they should be, not just mildly swollen; Glands that feel hard or don't move when you push on them
From Wikipedia, the free encyclopedia. Database normalization, or simply normalization, is the process of organizing the columns (attributes) and tables (relations) of a relational database to reduce data redundancy and improve data integrity.
Usually, it's because the layout works better in a report, or user interface after pivoting. Data on a normalized database may result in data in the shape of multiple records, where the UI wants to see those records as fields. Data normalization is great, but when it comes to representing data in a concise, natural format, pivoting is often necessary.
