DBMS and MySQL Complete Course Beginner to Advance

Learn how the entity relationship model describes data with entities, attributes, and relationships, including simple, weak, and associative entities, primary keys, and attributes such as derived, multi-valued, and composite types.

Explore normalization basics, including why it prevents anomalies by dividing tables into atomic values with consistent data types, unique column names, and unordered row storage, focusing on first normal form.

Explains the fourth normal form (4nf) and its requirement to avoid multivalued dependencies in bcnf. Uses a course and hobby example to show decomposition into cid and subjects or hobbies.

Explore the fifth normal form, or project joint normal form, and learn how joint dependency governs lossless decomposition and safe table splitting.

Explore theta joins, a type of inner join using conditions. Learn how non join uses operators like less than, greater than, and not equals to join employee and department data.

Demonstrates left outer join, returning all matching rows plus rows from the left table, with department fields possibly blank, using employee and department tables.

Explore selection in relational algebra, denoted by sigma, to filter rows in an employee table and retrieve a specific row, such as the one where employee number equals two.

Explore the set difference operator in relational algebra by subtracting matching rows from the first table and displaying the remaining rows, illustrated with the employee and department tables.

Install MySQL workbench by downloading MySQL installer 8.0.32, setting up MySQL server and workbench, configuring port 3306, securing via root password, and updating environment paths.

Explore MySQL data types, including integer, decimal, varchar, blob, date, time, and boolean, and compare char vs varchar and fixed vs variable length storage.

Learn to use MySQL Workbench to create databases in MySQL, including logging in, navigating the interface, and writing the SQL syntax create database database_name. Remember SQL is case-insensitive.

Explore the alter table command to add, modify, rename, or drop columns in a MySQL table; see live edits on a student table, including subject and subject_code data types.

Learn how the truncate command in MySQL removes all rows from a table while preserving its structure, leaving the table intact but empty, as shown with the employee table.

Use the rename command in MySQL to rename a table, turning 'employee' into 'employee details', and verify the change with a DESCRIBE of the new table after refreshing the database.

Learn to use the MySQL update command to modify table data with set and where clauses, verify changes with select, and handle safe update mode.

Enforce data validity with a check constraint by creating a student table and enforcing that age must be greater than or equal to 16, demonstrated with insertions and constraint violations.

Apply the distinct clause with a select statement to remove duplicate rows from query results, returning unique names and salaries.

Explore sql functions in mysql using an employee table to compute average salary, max and min, count rows, concatenate strings, and fetch top or distinct salaries with order by limit.

Compare recoverable and non-recoverable schedules in databases. Recoverable schedules allow rollback before commit, while non-recoverable ones cannot, risking irreversible commits and read-after-write conflicts.
