This repository contains my work and notes as I progress through the book "7 Databases in 7 Weeks". The book covers a range of modern database technologies, focusing on practical usage and conceptual understanding.

• Databases are essential for understanding and leveraging data, much like the importance of oil in energy and industry.
• Gaining knowledge of databases enhances one's ability to manage and utilize the growing corpus of data for various projects or entrepreneurial ventures.
• "NoSQL" represents a range of non-relational database systems that have become mainstream in technology, complementing traditional SQL databases.
• Both NoSQL and SQL databases continue to evolve and are crucial in expanding the applications of data.
• The book explores seven different databases across five genres, providing a comprehensive understanding of modern database technologies.
• It is designed for application developers and data engineers, offering practical exercises and discussions to deepen understanding of each database system.
• The book encourages a linear reading to build on concepts progressively, as some are only introduced in detail in early chapters.
• The focus is on practical usage and conceptual understanding, rather than installation and detailed administration of databases.
