ACID: Atomicity: Transaction must be all or nothing. Consistency: Valid state transitions only. Isolation: Independent transaction processing. Durability: Permanent transaction effects. 2. Normalization Primary Key: Unique identifier for records. Foreign Key: Links two tables based on a relationship. Candidate Key: Potential primary key. 1NF (First Normal Form): Eliminate duplicate columns, ensure atomicity. 2NF (Second Normal Form): Remove partial dependencies (non-key attributes depend on full primary key). 3NF (Third Normal Form): Remove transitive dependencies (non-key attributes depend only on the primary key). 3. Denormalization Denormalization: Merging tables for read optimization at the cost of write complexity. 4. Types of Databases Relational (RDBMS): Data stored in tables, SQL used (e.g., MySQL). NoSQL: For unstructured data (e.g., MongoDB). 5. SQL Queries SELECT: Retrieve data. INSERT: Add records. UPDATE: Modify data. DELETE: Remove records. JOINS: INNER JOIN: Return matching records. LEFT JOIN: Return all left table records and matched right table records. RIGHT JOIN: Return all right table records and matched left table records. FULL JOIN: Return all records from both tables. GROUP BY: Aggregate data by columns. HAVING: Apply conditions to groups. Aggregate Functions: COUNT(), SUM(), AVG(), MIN(), MAX(). 00:00 Intro 00:49 What is DBMS? 01:52 What is Database? 02:35 Acid properties 06:20 Geeks for Geeks course 09:55 Normalisation 13:35 1NF 14:05 2NF 15:52 3NF 17:22 Denormalization 18:25 Types of Database 19:44 Sql Queries 30:50 Transaction and concurrency control 32:10 Table level 32:28 Row level 33:12 Page level 34:13 Optimistic locking and Pessimistic locking 36:05 Deadlock 37:17 Indexing 40:00 Advantages and Disadvantages 41:05 DBMS keys recap 42:40 Stored procedure 42:55 Trigger 43:30 View 44:05 Usecases to know 45:20 Cap theorem 49:20 Conclusion ------------------------------------------------------------------------------------------------------------------------------------------------------- Whatsapp Channel: https://whatsapp.com/channel/0029VaYI...
