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.
Decomposition takes an existing (insufficiently normalized) database design and improves it based on the known set of dependencies. Edgar F. Codd, the inventor of the relational model (RM), introduced the concept of normalization and what we now know as the First normal form (1NF) in 1970.
