What is normalization? When you normalize your data, you are dividing your data into multiple collections with references between those collections. Each piece of data will be in a collection, but multiple documents will reference it. This means, to change your data, you only need to update one document, because that data is only defined once.Oct 28, 2015 ...

Normalization is important for many reasons, but chiefly because it allows ...Designing a Normalized State. The basic concepts of normalizing data are: Each type of data gets its own "table" in the state.

Normalization is a technique for organizing data in a database. It is important that a database is normalized to minimize redundancy (duplicate data) and to ensure only related data is stored in each table. It also prevents any issues stemming from database modifications such as insertions, deletions, and updates.Because of variability in the generation of read count data, the observed log fold-change will in general not be exactly 0, so the Oracle normalization method (normalizing the data with the correct normalization factors given the simulation) serves as a baseline.
