What is a bit?

A bit is a binary digit.The smallest increment of  data on a machine. A bit can hold only one of two values: 0 or 1.

What is a Byte?

Normalization

Normalization is a process for evaluating and correcting table structures to minimize data redundancies, thereby reducing the likelihood of data anomalies. Normalization starts by identifying the dependencies of a given relation and progressively breaking up the relation (table) into a set of new relations (tables) based on the identified dependencies. Normal Forms 0NF            Multi-valued attributes exists 1NF           Any multi-valued attributes (repeating groups) have been removed. 2NF           Any partial functional dependencies have been removed 3NF           Any transitive dependencies have been removed BCNF           Any anomalies resulting from functional dependencies have been removed 4NF           Any multi valued dependencies have been removed 5NF           Any remaining anomalies have been removed The table in 0NF : eliminate the nulls by making sure that each repeating group attribute contains an appropriate data va

Database Types

Types of Databases Databases can be classified according to the number of users, o    Single user database - A single-user database that runs on a personal computer is called a desktop database o    Multi user database ·          Workgroup database - the multiuser database supports a relatively small number of users (usually fewer than 50) or a specific department within an organization ·          Enterprise database Databases can be classified according to the database location(s), o    Centralized database - a database that supports data located at a single Site. o    Distributed database – a database that supports data distributed across several different sites The most popular way of classifying databases today, however, is based on how they will be used and on the time sensitivity of the information gathered from them. o    operational database (sometimes referred to as a transactional or production database) - A database that is designed primarily to suppor
