Explore authorization and ddl commands, including read and insert permissions, updates, and constraints; learn about slowly changing dimensions and scd type 2, domain constraints, and assertions.
Explore data definition language concepts to design schemas, define constraints, and understand how DDL, data manipulation language, and transaction data control language enable normalization and referential integrity.
Learn how read, insert, and update authorizations govern access in MySQL databases, and review DDL and DML concepts, including create, alter, drop, rename, constraints, and slowly changing dimensions type two.
Learn to alter table structures using sql, adding or modifying columns, setting data types and constraints (primary key, not null), and dropping or renaming columns or tables.
Explore data manipulation language basics, including the select command, and contrast procedural and declarative DML; learn how declarative queries optimize retrieval and see examples with select, insert, update, and delete.
Explore the insert command in SQL, including inserting single or multiple values, data type constraints, and how inserts affect related tables and key relationships.
learn how primary keys enforce uniqueness and non-null values and how foreign keys link tables for joins. explore composite primary keys and the use of constraints to manage table relationships.
Learn how primary keys uniquely identify records and how foreign keys link tables via project_id to enforce referential integrity, and compare truncate versus delete for data refresh.
Explore SQL procedures to load big data tables and manage data with delete, truncate, and triggers, then master set operations including union, union all, and intersect to combine results efficiently.
Explore grouping sets and the like operation in sql, using group by, having, and order by to analyze department headcounts and salaries.
Explore rank, dense_rank, and row_number in sql, including how ties affect ranking, how partition by and order by power descending shape results, and a primer on views and triggers.
