How to become a data analyst in 2022.?
Data and Information are two factors for the growth of any organization and as per the market survey data analytics is the most demanding field in the current IT sector. companies store data inside various relational database management systems like MySQL, Oracle, and DB2 and the next task is to convert data into meaningful information. now the question is how companies generate meaningful information from the raw data. actually, this is the point where there is a need for a data analyst. In this blog, we are going to answer How to become a data analyst in 2022.
Data analysis or analytical process is the statistical and logical derivation of data from many sources, databases, streams of consciousness, or mass aggregates to create meaningful and reliable answers. It is the process of entering large quantities of data into a computer in such a manner to be used in developing models to produce meaningful answers about the nature of the subject at hand. Data analysis can be thought of as the logical and quantitative legerdemain that is required to provide meaningful answers to questions.
Machine Learning and Artificial Intelligence are two revolutionary technology that will give many job opportunities for students and professionals.
What is Data Analysis.?
Data analysis is the process of cleaning and transforming raw data to find meaningful information for any business that helps to make decisions for the organization. The goal of data analysis is to extract meaningful information from the raw data and building the decision based on the data analysis. companies use the latest tools and technologies such as python programming, R programming, and anaconda, Numpy, pandas matplotlib, and tableau where professionals build predictive models for business.
“Data” is, in essence, a process of organizing, categorizing, categorizing, analyzing, comparing, reasoning, viewing, and even discarding data. Data Mining finds its roots in mining which is a type of mining of ore. Extracting and extracting. Exploiting (processing) the raw material. Well, if you want to extract data, why can’t you just read it? No need for mathematics! The data already exists. Data mining is a software business. It gives companies the chance to maximize the commercial value of the data they have and that they are about to collect.
Essential Subjects to be a Data Analyst.
Python Programming
Python is the most demanding and widely used programming language being used for data analysis and software development. if you are planning to be a data analyst, then you need to know the python libraries such as NumPy, pandas, seaborn, and matplotlib in order to clean and extract meaningful information. Python is a dynamically typed, case-sensitive language and It is a widely-used programming language across the globe.
Statistics
Statistics gives you techniques that help in summarizing data and this field is developed to understand uncertainties, if you are a Data Analyst then you must know the concept of statistics in order to analyze the data. companies use statistical tools to build predictive models and these models are further used to make meaningful future predictions for the organizations and build decisions. You should have knowledge of statistics if you are planning to be a Data Scientist. Learn Data Analysis from the best industry experts.
Machine Learning
Machine Learning is a popular domain of Artificial Intelligence and it is one of the most demanding technology in the current analytical world. it makes a programming model that learns hidden and meaningful patterns from the varieties of data and forecasts the future results for any business. machine-learning experts build mathematical models using python programming language and further these models are used to make better decisions for the organizations.
Tableau
Tableau is the most popular analytical platform for data visualization. It also increases data power for the organizations. It is a business intelligence platform that is designed for the individual and business that convert information into visual graphs. the main purpose of the tableau is to connect and extracting information from different data storage systems. It can retrieve information from any data source like Excel, PDF, and Oracle.

What is the role of a data Analyst.?
Data scientists today have a tough job to do. The old analytical tools like spreadsheets are a thing of the past and the industry is at a dire point in the maturity curve. All sorts of data scientists are needed to extract useful insights from data and to make it useful and actionable. Here is a look at the hard work that goes on behind the scenes of a data scientist, and some insight into why that work is so important.
Data Analyst is responsible for identifying the business need and prepare data model and analyze data. he/she is responsible for cleaning raw data, making machine learning models, building analytical reports, and presentation of analyzed data using various graphs and charts. data analyst is an expert in python programming, analytical tools such as tableau and SQL.
Skills Required to be a Data Analyst.
Knowledge of R and Excel
R programming is also used in data analysis and mining, you should have knowledge about R and its analytical libraries such as ggplot and tidyverse and how to work on R studio apart from this, You should be aware of MS Excel statistical methods, Regression Techniques, Graphs and charts for data visualization and Data Analysis.
Knowledge of SQL and Database
Most of the data is stored in RDBMS databases and SQL is a query language that is being used for data loading and processing. according to me, SQL knowledge is a must to be a data analyst and many companies use SQL to fetch and filter meaningful insights from the huge amounts of data.
Knowledge of Data Warehoue
Being an Expert in Data Analysis, One should have knowledge of current data-warehouses such as Hive and how distributed data is being stored and managed in these data warehouses moreover, you should be aware of ETL operations in the organization and current ETL Tools such as Sqoop.
Knowledge of Data Cleaning and Munging
Data Cleaning is the first task that is required before analyzing any data such as how to handle Null values and how to filter data based on some condition. professionals use pandas libraries where we create Data Frames and further we filter and clean these data frames.
