Why is it important to design a database before creating one?

Designing a database before creating one is important to ensure efficiency, avoid data duplication, and to understand the business processes that the database needs to support.

What is the difference between data and information according to the script?

Data is something that has meaning to the recipient and is unprocessed, while information is the result of processing data through a specific model or formula, which can be used to increase knowledge for the recipient.

What is a database?

A database is a centralized and structured collection of data stored in a computer system, which provides facilities for retrieving, adding, modifying, and deleting data as needed by the user.

What is the role of a database administrator?

A database administrator is responsible for managing the database, ensuring its integrity, and addressing any issues such as corruption, deletion, or anomalies that may occur.

What are some examples of database management systems mentioned in the script?

Examples of database management systems mentioned in the script include MySQL, PostgreSQL, MongoDB, Access, SQL Server, and others.

What is the significance of normalization in database design?

Normalization in database design is significant for organizing data to minimize redundancy and dependency by applying rules to structure data in a way that supports data integrity and efficient data retrieval.

How does the script relate the concept of a database to everyday life?

The script relates the concept of a database to everyday life by mentioning examples such as Facebook, Instagram, and banking systems, where databases are used indirectly to store and manage data like photos, messages, customer information, and transactions.

What is the purpose of the Entity-Relationship Diagram in database design?
