What is a Database?

A database is a collection of structured data stored electronically in a computer system. Databases are used to store and manage data in a way that allows it to be easily accessed, modified, and retrieved. Data in a database is typically organized into tables, which are made up of rows and columns. Each row represents a single record, and each column represents a specific attribute of that record.

Why Use a Cloud Database?

There are many benefits to using a cloud database, including:
Scalability: Cloud databases can be easily scaled up or down to meet your changing needs.
Reliability: Cloud databases are hosted in redundant data centers, which ensures that your data is always available.
Security: Cloud databases are protected by multiple layers of security, including encryption and access control.
Cost-effective: Cloud databases are typically more cost-effective than on-premises databases.
