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.
Normalization usually means transforming the data you are working with to a common frame of reference. I can give you a good example of data normalization for one of the areas I work in a lot. It is a function called the Z-Score. What it does is allows you to convert and data that is a Normal Distribution into a frame of reference where the Mean is Zero and the variation is expressed in standard deviations. The reason that data is usually normalized is that it takes out the matter of scale in the data and allows as much as possible an âapples to applesâ comparison of data.
