In this tutorial, we will learn to write a Python program to replace the first occurrence of a vowel with a hyphen (‘-‘) in a given string. Suppose if some given input is “ram” then the output will look like “r-m”. For Example: Program to Replace first occurrence of Vowel with ‘-‘ in String In … Read more
In this tutorial, you will learn to write a Python program to find the Prime factors of a given input integer. Prime factorization is a mathematical process of breaking down a number into its prime factors. We can also say that it is a representation of a composite number as a product of its prime … Read more

Database languages are specialized programming languages that are used to communicate with and manipulate databases. There are two main categories of database languages: data definition languages (DDL) and data manipulation languages (DML). In other words, a database language is a programming language that is used to create, modify and maintain the structure and content of … Read more
Data independence is also called Data abstraction. In the 3-level architecture of D.B.M.S, we see the purpose of all three levels of architecture. In data independence, we discuss the use of these levels. Data independence is the concept of making data independent from the users. The basic aim of the user is to access data, … Read more
The objective of database schema is to recognize different tables and fields of each table. Schema also describes how the relationship is established between tables. This helps to identify constraints in the system. The subschema is a subset of the schema and the subschema inherits the same property as the schema. Schema can be divided … Read more
