            <p>Data management is a critical pillar of modern organizational operations, necessitating robust systems to store, organize, and retrieve information efficiently. This course provides a comprehensive foundation in relational databases, distinguishing them from traditional spreadsheet applications and exploring their underlying principles. Learners will examine the core architecture of relational database management systems (RDBMS), gaining a clear understanding of essential components such as tables, rows, and columns. Furthermore, the curriculum delves into the critical role of database keys—specifically primary and foreign keys—in establishing relationships between data points and maintaining strict data integrity across complex systems.</p>

<p>Building upon this structural knowledge, the course introduces Structured Query Language (SQL) as the industry-standard tool for interacting with relational databases. Participants will learn to construct standard SQL commands, focusing heavily on Data Query Language (DQL) to extract meaningful insights. Through detailed instruction on the SELECT statement and the WHERE clause, learners will acquire the ability to filter rows and retrieve specific datasets with precision. The curriculum then progresses to data summarization techniques, utilizing aggregate functions such as COUNT, SUM, AVG, MIN, and MAX to transform raw data into concise, actionable metrics. Supported by rigorous knowledge check quizzes to reinforce comprehension, this program equips participants with the practical skills required to navigate relational databases and execute fundamental SQL queries with professional confidence.</p>
