To reduce the need for restructuring the collection of relations as new types of data are introduced, and thus increase the life span of application programs. Chapter 5: Normalization of Database Tables. Normalization is a formal process for assigning attributes to entities. Helps eliminate data anomalies where insertions, deletions, updates destroy the integrity of the database. At the conclusion of this process the database will be logically correct. Cloud Datastore Features Cloud Datastore is a highly-scalable NoSQL database for your web and mobile applications Rich Admin Dashboard View entity statistics, query your database, view indexes, and backup/restore your data. Multiple Access Methods Access your data via our JSON API, open-source clients, or community maintained ORMs (, ). Fully Managed Cloud Datastore is fully managed, which means Google automatically handles sharding and replication in order to provide you with a highly available and consistent database. Diverse Data Types Datastore supports a variety of data types, including integers, floating-point numbers, strings, dates, and binary data among others. ACID Transactions Ensure the integrity of your data by executing multiple datastore operations in a single transaction with ACID characteristics, so all the grouped operations succeed or all fail. Database Normalization Database Normalization The term Normalization is a process by which we can efficiently organize the data in a database. It associates relationship between individual tables according to policy designed both to care for the data and to create the database more flexible by eliminating redundancy and inconsistent dependency. In other words, Database normalization is a process by which a presented database is tailored to bring its component tables into compliance with a sequence of progressive standard forms. It is an organized way of ensuring that a database construction is appropriate for general purpose querying and also includes the functions of insertion, deletion and updating. Edgar Frank Codd was the person who introduced the process of database normalization firstly in his paper called A Relational Model of Data for Large Shared Data Banks. The two main objective of database normalization is eliminating redundant data and ensuring data dependencies make sense and make sure that every non-key column in every table is directly reliant on the key and the whole key.

If data that exists in more than one place must be changed because it wastes disk space and the data must be changed in exactly the same way in all locations of the table. Data dependencies can make data easier to access because it is easy to find the path of the data. Inconsistent dependencies will create the huge problem to find the data of particular person or thing.
