Before the advent of relational databases, managing and organizing large amounts of data was a daunting task. People relied on manual record-keeping systems, such as paper files and spreadsheets, which were prone to errors, difficult to update, and challenging to search through. There was no efficient way to store, retrieve, and analyze data, leading to inefficiencies and information overload. It was a time-consuming and cumbersome process, often resulting in data inconsistencies and inaccuracies.
Relational databases are like super-powered organizers for data. They provide a structured and efficient way to store, manage, and access information. Imagine a virtual filing cabinet that keeps everything neat, tidy, and easily accessible. Relational databases use tables to store data, with each table consisting of rows and columns. These tables are connected through relationships, allowing us to retrieve information from multiple tables simultaneously. It's like having a digital assistant that can quickly find the exact piece of information you're looking for.
