Database Management Basics

Database management is the process to manage information that is essential to an organization’s business operations. It involves storing and distributing data it to users and applications making edits as needed as well as monitoring changes in data and making sure that data integrity is not compromised due to unexpected failure. It’s a component of a company’s total informational infrastructure which aids in decision making and growth for the business as well as compliance with laws like the GDPR and the California Consumer Privacy Act.

In the 1960s, Charles Bachman and IBM along with others created the first database systems. They evolved into information management systems (IMS), which allowed huge amounts of data to be stored and retrieved for a variety of reasons. From calculating inventory to aiding complicated financial accounting functions, and human resource functions.

A database is tables that arrange data according to some schema, such as one-to many relationships. It uses the primary key to identify records and allows cross-references between tables. Each table contains a number of fields, also known as attributes, which provide information about the data entities. The most widely used kind of database is a relational model designed by E. F. “Ted” Codd at IBM in the 1970s. The concept is based on normalizing data to make it more user-friendly botosoftdev-001-site1.atempurl.com. It is also easier to update data because it does not require changing several databases.

Most DBMSs can accommodate different types of databases by offering different levels of external and internal organization. The internal level addresses costs, scalability, and other operational issues like the layout of the database’s physical storage. The external level is the representation of the database on user interfaces and applications. It could comprise a combination of different external views (based on different data models) and may include virtual tables that are computed from data that is generic to enhance performance.
