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.
During the physical design process, you convert the data gathered during the logical design phase into a description of the physical database, including tables and constraints. Physical design decisions, such as the type of index or partitioning have a large impact on query performance. See Chapter 6, Indexes for further information regarding indexes. See Chapter 5, Parallelism and Partitioning for further information regarding partitioning. Logical models use fully normalized entities.
