Steps Required to Perform Data Manipulation

The steps we perform in Data Manipulation are:

• Mine the data and create a database: The data is first mined from the internet, either with API requests or Web Scraping, and these data points are structured into a database for further processing.
• Perform data preprocessing: The Data acquired from mining is still a little rough and may have incorrect values, missing values, and some outliers. In this step, all these problems are taken care of, either by deleting the rows or, by adding the mean values in all missing areas (Note: This is only in the case of numerical data.)
• Arrange the data: After the data has been preprocessed, it is arranged accordingly to make analysis of data easier.
• Transform the data: The data in question is transformed, either by changing datatypes or transposing data in some cases.
• Perform Data Analysis: Work with the data to view the result. Create visualizations or an output column to view the output.

We’ll see more on each of these steps in detail below.

Have you ever wondered how data enthusiasts turn raw, messy data into meaningful insights that can change the world (or at least, a business)? Imagine you’re given a huge, jumbled-up puzzle. Each piece is a data point, and the picture on the puzzle is the information you want to uncover. Data manipulation is like sorting, arranging, and connecting those puzzle pieces to reveal the bigger picture.

Data Manipulation is one of the initial processes done in Data Analysis. It involves arranging or rearranging data points to make it easier for users/data analysts to perform necessary insights or business directives. Data Manipulation encompasses a broad range of tools and languages, which may include coding and non-coding techniques. It is not only used extensively by Data Analysts but also by business people and accountants to view the budget of a certain project.

It also has its programming language, DML (Data Manipulation Language) which is used to alter data in databases. Let’s know what exactly Data manipulation is.
