Storing data is crucial for the preservation of knowledge. The archives that give us a look into our past exist because information was gathered and stored for reference.
The way data is stored has also evolved over the years. From writing on cave walls to scrolls and books, and more recently, to digital notebooks and digital storage systems.
As data-driven problem-solving grows in popularity, likewise the different methods of storage. Databases are a more modern way of storing data, and this method of storing data is conveniently and easily accessible.
In this article, we’ll explore the definitions and types of databases, including their importance in storing personal or business data. But before diving into databases, let’s talk about data.
What is Data?
Data can be basic values or facts. Computers use data to perform tasks or process it to produce information. In fact, computers need data because, without it, they wouldn’t function as they should.
There are different ways to represent and organise data, particularly data used in computer systems and how it is represented in digital form and organised in databases. Data can be represented as either digital or analogue;
Digital data can also be images, videos, and software, all of which can be shared over networks without losing their quality over time.
Data is generated through various means, like manual entry (e.g., filling out forms) or social interactions (e.g., comments). All of this data and information gathered must be stored somewhere and processed to develop meaningful insights.
This is where databases become useful, as they provide a structured and efficient way to store and manage data. Data storage has evolved with the introduction of databases and database management systems technology. Data is organised in a structured way that allows easy storage, retrieval and management
What is a Database?
A database is an organised collection of structured data or information stored in a computer system. It is used for storing, maintaining, and accessing a variety of data, which can be organised in tables, rows, columns, and indexes to facilitate easy retrieval of relevant information.
Databases are also used to extract business intelligence, aiding in decision-making that benefits the customers.
Purpose of a Database
The different purposes for using or creating a database include;
To keep track of information: Storing all data in one area is efficient, and it ensures that you keep track of data and also receive the most updated version of data.
Consistency: The database helps to maintain data integrity and accuracy, which ensures that data remains consistent across multiple instances and is always organised.
Manage large amounts of data: Database systems manage large volumes of data, and can be used to quickly access, modify, and essentially manage data efficiently.
Improved Decision Making: Databases provide data on insights into a company's sales trend or other relevant information that the business requires. This data can help businesses make better and more informed decisions.
Data Security: Database secure data. It also ensures that it maintains backup copies to restore the database in case there's a breach or failure.
