A database is a one-stop computerized location to find specific information. Note, that doesn't mean ALL information, just whatever info THAT database has. The benefit is having a lot of info available in one place. The detriment is a database can seem deceiving if a person does not realize the database does not mean all info. For example, NO library database contains ALL books ever published. But it does contain all books in THIS library.

RafaA database is a structured collection of data that is organized for easy access and retrieval. It is beneficial to use databases because they provide a centralized location for storing and managing data, allowing for efficient data handling, retrieval, and manipulation. Databases ensure data integrity, allow for scalability, and enable multiple users to access and work with the data simultaneously.

How do we use databases?
To use a database, first design a schema to define the structure of your data. Then create tables to store data following the schema. You can then use SQL queries to manipulate and retrieve data from the database. Most databases also provide tools or APIs to interact with them programmatically.
Different between distributed and decentralized on database?
Distributed databases are spread across multiple nodes or locations, while decentralized databases operate without a central authority or control. Distributed databases may have a centralized component for coordination, while decentralized databases use consensus algorithms for decision-making. Decentralized databases offer higher resilience and security against single points of failure compared to distributed databases.
Where do you put information in a database?
Information in a database is organized into tables, which consist of rows and columns. Each row represents a record and each column represents a field of data. Data is stored in cells at the intersection of rows and columns.
What is a database in which ALL the data is stored in a single table known as?
A database in which ALL the data is stored in a single table is known as a flat-file database. This type of database lacks the relational structure found in more traditional databases that use multiple tables to store and organize data. Flat-file databases are simple but may limit the ability to efficiently query and manage data.
What are databases people use?
People commonly use relational databases such as MySQL, Oracle, and SQL Server for managing structured data. Other types of databases like NoSQL (e.g., MongoDB, Cassandra) are preferred for handling unstructured or semi-structured data efficiently. Additionally, cloud-based databases such as Amazon RDS and Google Cloud Spanner are gaining popularity due to their scalability and cost-effectiveness.
