+
+Lesson Date: 10|02|2025.
+
+Introduction:
+A database is an organized collection of data that can be easily accessed, managed, and updated.
+They allow for efficient data storage, retrieval, and manipulation, which is essential for dynamic applications.
+
+Relational databases are a specific type of database that stores data in tables (or relations). Each table consists of rows and columns,
+where each row represents individual entry or a record that exists in a table and each column holds specific information about
+every record in the table.
+
+SQL (Structured Query Language) as the standard language used to communicate with relational databases. It is used for querying, updating, 
+and managing data.

+Polymorphism : Implement Method Overriding and Overloading.
+
+(Batch 26).
+
+Lesson Date: 11/02/2025.
+
+Introduction.
+polymorphism is one of the fundamental of oop concepts that enhances the flexibility and scalability of code. 
+Derived from the Greek words "poly" (meaning many) and "morph" (meaning forms), polymorphism allows objects to be treated as instances of their parent class,
+enabling a single interface to represent different underlying forms (data types).
