A database is vital in today’s world, as we use them in various activities such as online shopping, logging in, and accessing bank accounts without being aware of it.
The idea of a “data bank” has been present since before the internet and computers were invented. Consider how information was stored prior to the digital era.
Developers with a web-hosted website or application should have a basic understanding of the subject.
We will address this here. Keep reading to learn about the significance of a database for your website or web application!
What does the term “database” refer to?
A database is a computer system that stores structured information on a specific topic, facilitating the search, handling, and sorting of data.
Databases can also illustrate connections between various data points in certain instances.
While there are various methods to store information on the internet, this is among the most commonly used.
Databases not only store information but also aid in managing and comprehending data.
The first computerized databases started appearing in the 1960s as computers became a more cost-effective choice for private organizations.
As prices decreased, it became simpler to shift data storage and databases to computers.
Protecting user data is essential.
Since the 2010s, there has been increased awareness about data, including the rise of big data and a stronger focus on data security.
Large organizations now consider data security a top priority due to the General Data Protection Law (LGPD).
The user should feel secure knowing that their data is personal and confidential.
Explore the following security measures for managing databases in applications and websites:
- Identify important and confidential information.
- Be prepared for leaks or cybercriminal attacks by having a plan in place.
- Grant permissions to restrict data access.
- Avoid using the identical database for testing new applications.
What is the significance of having a database for your website?
There are two categories of websites based on their interaction with databases: static and dynamic.
Familiarity with these terms is necessary as the significance of a database for your site will vary based on its compatibility.
Static webpage
This website remains consistent across different browser page loads.
If a user clicks on a button, there is no change in the page’s layout or content.
Changes are only made when a user loads a new page or an administrator loads a different page in the web browser.
Dynamic Website
Pages of a dynamic website alter each time they are accessed.
When a user interacts with an image or text, modifications are visible on the page.
Database development involves constructing a website that stores content in columns and tables rather than server files.
A static site stores data in the file system, while a dynamic website is typically based on a database.
More features are provided by a dynamic website compared to a static one.
Examples of how databases are used in real-world situations
Some real-life instances of uses comprise the following:
- Shopping cart;
- Customized main page.
- Advanced capability to search.
Explore how a database system interacts with various web applications.
Online retail stores and digital storefronts
These companies utilize data-driven websites to benefit from anticipated fluctuations in prices, promotions, and offerings, guaranteeing that users have access to current information.
Content Management Systems abbreviated as CMS.
If a website utilizes a CMS, it will have a focus on databases. This allows users to update content on the site easily, even without requiring specialized programming knowledge. WordPress serves as a prime illustration of this functionality.
Blogs are online journals.
Many blogs and forums rely on databases for frequent user interactions, leading to immediate updates on the page when users leave comments or engage with the site.
Types of Databases available?
You are already familiar with the concept of a database, including its purpose and how it works for websites and applications.
How are they segregated and which classification should I select for my application?

Relational Database – A type of database system
Databases are beneficial for storing extensive amounts of data across various categories, and to access and utilize this data, structured query language (SQL) is employed.
