This comprehensive course is designed for backend developers and those preparing for technical interviews. Participants will learn from the ground up about relational database management systems (RDBMS) and Structured Query Language (SQL). They will learn how to design scalable and secure databases, and will master fundamental SQL commands, along with real-world use cases and hands-on exercises. This course provides a structured approach that helps learners confidently work with relational databases, from creating tables and manipulating data to advanced topics such as subqueries and joins. They will understand how key components such as primary and foreign keys maintain data integrity, and they will explore the power of transactions and locking for multi-user environments. They also learn how to optimize queries with indexing and the EXPLAIN keyword to increase performance.<\/span><\/p>\n<div data-purpose=\"safely-set-inner-html:description:description\">\n<p data-sourcepos=\"9:1-9:409\"><span style=\"vertical-align: inherit\">By the end of this course, learners will be able to build robust databases, write optimized queries, manage user privileges with the Data Control Language (DCL), and implement security best practices against common vulnerabilities. Triggers, views, and transaction control are also covered, providing learners with a complete toolkit to tackle complex data challenges in any production environment. With its practical knowledge and applied expertise, this course will prepare participants to stand out, whether reviewing SQL for an upcoming interview or enhancing their back-end development skill set. By joining this course, learners will unlock the power of RDBMS and SQL for their projects and professional growth.<\/span><\/p>\n<h3 data-sourcepos=\"13:1-13:24\"><strong><span style=\"vertical-align: inherit\">What you will learn<\/span><\/strong><\/h3>\n<ul data-sourcepos=\"15:1-27:0\">\n<li data-sourcepos=\"15:1-15:81\"><span style=\"vertical-align: inherit\">Will understand the relational model, ACID guarantees, and the advantage of SQL for data integrity.<\/span><\/li>\n<li data-sourcepos=\"16:1-16:79\"><span style=\"vertical-align: inherit\">It will install and configure MySQL, then practice with real datasets.<\/span><\/li>\n<li data-sourcepos=\"17:1-17:80\"><span style=\"vertical-align: inherit\">It will work practically with DDL, DML, DCL and TCL for complete database control.<\/span><\/li>\n<li data-sourcepos=\"18:1-18:91\"><span style=\"vertical-align: inherit\">It will create robust tables, define keys, and handle various SQL data types.<\/span><\/li>\n<li data-sourcepos=\"19:1-19:97\"><span style=\"vertical-align: inherit\">It uses SELECT, INSERT, UPDATE, DELETE and will handle NULL values \u200b\u200beffectively.<\/span><\/li>\n<li data-sourcepos=\"20:1-20:97\"><span style=\"vertical-align: inherit\">You will master advanced clauses \u2014 GROUP BY, HAVING, ORDER BY \u2014 and the use of subqueries.<\/span><\/li>\n<li data-sourcepos=\"21:1-21:99\"><span style=\"vertical-align: inherit\">It will link tables using joins (internal, external) and foreign keys for data relationships.<\/span><\/li>\n<li data-sourcepos=\"22:1-22:71\"><span style=\"vertical-align: inherit\">It will optimize performance with indexes, EXPLAIN, and targeted query tuning.<\/span><\/li>\n<li data-sourcepos=\"23:1-23:98\"><span style=\"vertical-align: inherit\">It will secure databases through user permissions, parameterized queries, and secure passwords.<\/span><\/li>\n<li data-sourcepos=\"24:1-24:100\"><span style=\"vertical-align: inherit\">It will implement transactions, fine-grained locking, and rollback for fail-safe operations.<\/span><\/li>\n<li data-sourcepos=\"25:1-25:90\"><span style=\"vertical-align: inherit\">It automates logic and enforces rules with triggers to simplify application logic.<\/span><\/li>\n<li data-sourcepos=\"26:1-27:0\"><span style=\"vertical-align: inherit\">It will use views, temporary tables, and derived queries to retrieve cleaner data.<\/span><\/li>\n<\/ul>\n<h3 data-sourcepos=\"28:1-28:30\"><strong><span style=\"vertical-align: inherit\">This course is suitable for people who:<\/span><\/strong><\/h3>\n<ul data-sourcepos=\"30:1-33:89\">\n<li data-sourcepos=\"30:1-30:77\"><span style=\"vertical-align: inherit\">Aspiring backend developers looking for a strong foundation in databases.<\/span><\/li>\n<li data-sourcepos=\"31:1-31:92\"><span style=\"vertical-align: inherit\">Programmers preparing for interviews that test SQL and RDBMS concepts.<\/span><\/li>\n<li data-sourcepos=\"32:1-32:59\"><span style=\"vertical-align: inherit\">Computer science students looking for hands-on SQL practice.<\/span><\/li>\n<li data-sourcepos=\"33:1-33:89\"><span style=\"vertical-align: inherit\">Professionals looking to improve or refresh their skills in SQL and database design.<\/span><\/li>\n<\/ul>\n<\/div>\n<h3><span style=\"vertical-align: inherit\">Course details RDBMS &amp;
