Database Management Basics

Database management is the system for managing data that supports the company’s business operations. It involves storing data, distributing it to users and applications, editing it as needed and monitoring changes to data and stopping data corruption due unexpected failure. It is part of the overall informational infrastructure of a company which supports decision-making and corporate growth as well as compliance with laws such as the GDPR and California Consumer Privacy Act.

In the 1960s, Charles Bachman and IBM along with other companies developed the first database systems. They developed into information management systems (IMS), which allowed large amounts of data to be stored and retrieved for a variety of purposes. From calculating inventory to supporting complex financial accounting functions and human resource functions.

A database is a set of tables that organizes data in accordance with a specific pattern, such as one-to-many relationships. It utilizes primary key to identify records and allows cross-references between tables. Each table is comprised of a variety of fields, known as attributes, that provide information about the data entities. Relational models, created by E. F. “TedCodd Codd in the 1970s at IBM and IBM, are the most well-known database type currently. This model is based upon normalizing the data, making it easier to use. It is also easier to update data because it doesn’t require the modification of certain sections of the database.

Most DBMSs support different types of databases by offering different levels of internal and external organization. The internal level is concerned with cost, scalability, as well as other operational issues, including the physical layout of the database. The external level is the representation of the database in user interfaces and applications. It can include a combination of different external views (based on the different data models) and could also include virtual tables that are computed from generic data in order to improve performance.
