What is Data Analytics?

Data analytics is a fundamental process that involves the careful analysis of raw data in order to indicate patterns, draw conclusions, and make well-informed decisions. This technique contains a wide range of methodologies, from basic data aggregation and descriptive analysis to sophisticated methods such as predictive modeling and machine learning.

Key Concepts in Data Analytics

Data Types:

Structured Data: 

Organized and easily searchable (e.g., SQL databases, web form results).


Unstructured Data: 

Information that doesn’t t into a predefined data model (e.g., text documents, social media posts, customer feedback).

 

Semi Structured Data: 

Semi-structured data refers to data that doesn’t conform to the structure of traditional relational databases but has some organizational properties that make it easier to analyze than completely unstructured data. It typically includes tags, markers, or keys that help identify elements within the data. (e.g., emails, xml files, JSON files).


Descriptive Analytics:
Summarizing Data: Generating insights from historical data through summary statistics and visualization techniques.
Example: Creating bar charts to show sales trends over time.


Predictive Analytics:
Predicting forthcoming trends involves leveraging statistical algorithms and machine learning methodologies to forecast future occurrences based on past data patterns.
Example: Predicting future sales based on past performance and market trends.


Prescriptive Analytics:
Optimizing Decisions: Recommending actions to achieve desired outcomes by analyzing multiple possible scenarios.
Example: Suggesting pricing strategies to maximize pro ts based on market conditions and competitor analysis.
