A database is a collection of data that can be accessed by computers. Databases are used in many different applications, including business, Information Technology (IT), and Software Development.
In computing, a database typically refers to an electronic system consisting of one or more Computer files that are organized into tables and stored on a server. The data in the table may be queried using standard SQL commands.
What is the definition of a database in computing?
A database is an organized collection of structured data, or information, typically stored electronically in a computer system.
In computing, a database is a system for storing and retrieving data. A database is usually controlled by a database management system (DBMS). A database management system (DBMS) helps users search and retrieve data from a database. A database can be saved in a variety of ways, including as a single file or as a group of files. A database must be able to provide cross-referencing functionality.
Most databases use structured query language (SQL) for writing and querying data.
- A relational database is a digital database based on the relational model of data, as proposed by E. F. Codd in 1970. A software system used to maintain relational databases is a relational database management system (RDBMS). Virtually all relational database systems use SQL as their standard query language.
- A non-relational database, also called a NoSQL database, is a database that uses a different data model than relational databases. These data models allow for more flexibility when it comes to how data is organized and accessed.
Databases are beneficial because they can store a large amount of data effectively, allow for quick and easy data retrieval, support data modification and deletion, and enable sorting and searching using techniques like indexing and binary searching. Additionally, databases provide increased security for data compared to physical paper files.

History of Databases
The navigational DBMS was developed in the 1960s and allowed for applications to navigate around linked data sets. This approach formed into a large network, which influenced other database languages.
1970s, relational DBMS
Relational DBMS was popular in the 1970s because it was simpler and more efficient than earlier databases. The relational model had been proposed by E.F. Codd in 1970, and it found widespread use in the 1980s due to its convenience for client/server communication, parallel data transfers, and GUI usage. Integrated approach
IBM has a long history of developing integrated cloud database solutions. These solutions help to improve a company's data governance and data quality. The integrated approach has helped IBM to become one of the leading providers of cloud database services. The reference discusses how the integrated approach has helped in the past and how it can be used currently to help a company with data governance and quality.
Late 1970s, SQL DBMS
The SQL DBMS was designed in the late 1970s to make data access more convenient for non-programmers. The relational model was convenient for client/server communication, parallel data transfers, and a GUI. The SQL DBMS has revolutionized the way we store and access information. 1980s, on the desktop
In the 1980s, desktop computers were powered by spreadsheets and database software like dBASE. This made it easy for people to use and transfer data between different computers. The relational model appeared in the 1970s, but it wasn't widely adopted until the 1980s. The relational model led to the development of the internet. The relational model was convenient for client/server communication, parallel data transfers, and GUI usage.
In the 1990s, many programmers turned to object-oriented programming (OOP) to help manage data complexity. OOP allows developers to create objects that can be used and reused in different ways. This can make code more modular and easier to understand. Additionally, OOP can help reduce the amount of duplicate code, making applications more efficient.
2000s, NoSQL and NewSQL
NoSQL databases emerged in the early 2000s as an alternative to the more traditional relational databases. They are characterized by their ability to scale horizontally and store data in a variety of formats. This makes them particularly useful for handling large sets of distributed data. Some examples of NoSQL database systems include MongoDB, CouchDB, Cloudant, Memcached, Redis, Coherence, HBase, Big Table and Accumulo.
NewSQL is a relatively new category of database that aims to combine the best attributes of both XML and NoSQL databases. NewSQL systems use SQL queries for data manipulation and typically offer strong flexibility and scalability while still maintaining ACID compliance.
