Databases are organized collections of data that facilitate efficient storage,
retrieval, and management of information. They are essential for various
applications across industries, including business, healthcare, and technology.
This overview covers key concepts such as types of databases (relational,
NoSQL), database management systems (DBMS), and the use of Structured
Query Language (SQL) for data manipulation. It highlights the importance of
data integrity, security, and normalization, as well as emerging trends like
cloud databases and big data integration. Understanding these fundamentals
enables organizations to leverage data effectively for informed decision-making
and operational efficiency.

WHAT IS DATA?
Data consists of unprocessed facts
and figures that have no context or
meaning on their own. For example,
numbers, dates, and strings of text.
Raw Facts
Data refers to raw facts,
figures, or information that
can be processed, analyzed,
and interpreted to derive
meaning or insights.
When data is processed, organized,
or structured in a way that adds
context and meaning, it becomes
information.

DBMS is a software tool that allows people to, Store data, access data, process
data into useful information
• Case study
• Youtube
• Approximately 145 million videos
• 65,000 videos being uploaded every day
• 100 million videos are viewed daily • On top of this, there is all of the
comment data, user profile data, etc. (Wikipedia
This business could not exist without large scale management of data and
inexpensive data storage

YOUTUBE
University of Jhang
• Let’s say you want a list of the top 10 most popular videos on
YouTube, manually.
• You would need to have all 145 million videos printed out, along
with the number of views. • Assume one person could maybe look
through 8,000 videos in a day and find the most viewed ones in
their list • How would you do this?
