What you'll learn
About this course
In this Oraclecourse, you will understand the working of Oracle DBMS in-depth. First, you will start with an introduction to DBMS, the difference between data and database; after that, you will learn how to create tables and store or insert data inside them. Later, you will also learn various miscellaneous and small topics around Oracle, which are very important from an interview perspective.
Not only that, but you will also understand the core topics of SQL, such as functions, clauses, joins, and many more, which are used to write a query and find the resultant data for a problem in a database. At last, you are going to end this course by learning about SQL commands and Database objects.
Course outline
Database Management Systems (DBMS): Architecture and Storage
Define Database Management Systems (DBMS). Differentiate raw data from structured databases and explore core DBMS architecture designed to resolve data redundancy and management challenges.
DDL Basics: CREATE TABLE, Data Types, and Keys
Construct database schemas using the CREATE TABLE command. Define precise Oracle data types (VARCHAR2, NUMBER) and enforce referential data integrity by establishing Primary Keys and Foreign Keys.
Oracle Database Setup and Local Environment Configuration
Configure a functional local development workspace. Execute the step-by-step installation of the Oracle Database environment to write, test, and deploy SQL queries effectively.
The Relational Data Model: Attributes, Tuples, and Normalization
Master the theoretical foundation of Oracle SQL. Apply the Relational Model by mapping relations (tables), attributes (columns), and tuples (rows), and implement database Normalization principles.
Oracle Data Dictionary Views and Sequence Generation
Navigate critical Oracle functionalities for database administration. Query system metadata using Data Dictionary Views (USER_TABLES, ALL_OBJECTS) and automate primary key values via Sequence Generation.
SQL Operators: Arithmetic, Comparison, Logical, and Set Operations
Manipulate database records using Oracle SQL Operators. Apply Arithmetic operators for calculations, Comparison operators for filtering, Logical operators (AND, OR, NOT), and Set operators (UNION, INTERSECT) to combine query results.
Oracle SQL Functions: Single-Row and Aggregate Computations
Perform complex data transformations using built-in Oracle functions. Implement Single-Row functions (character manipulation, numeric math, date formatting) and Multiple-Row Aggregate functions (SUM, AVG, COUNT).
Core SQL Clauses: WHERE, GROUP BY, HAVING, and ORDER BY
Structure robust SQL queries to filter and sort enterprise data. Utilize the WHERE clause for row-level filtering, GROUP BY and HAVING for aggregated data segments, and ORDER BY for result sorting.
Advanced SQL: Subqueries and Nested Query Execution
Execute multi-step data retrieval using Nested Queries (Subqueries). Embed inner subqueries within outer queries to isolate specific values, perform comparative analysis, and resolve complex data fetching requirements.
Relational SQL Joins: Inner, Outer, Full, and Self Joins
Combine related dataset columns using relational SQL Joins. Execute Inner Joins for matched records, Outer Joins (Left, Right, Full) for unmatched records, and Self Joins for hierarchical data relationships.
Core SQL Command Categories: DDL, DML, DCL, and TCL
Categorize and execute the four pillars of SQL commands. Utilize Data Definition Language (DDL), Data Manipulation Language (DML), Data Control Language (DCL), and Transaction Control Language (TCL) commands like COMMIT and ROLLBACK.
Oracle Database Objects: Views, Indexes, and Synonyms
Optimize database performance and security using Oracle Database Objects. Abstract underlying table data using virtual Views, accelerate query retrieval speeds using Indexes, and simplify object referencing using Synonyms.
