Best Course for Data scientist in Pune!

Data science combines programming skills, domain expertise, the knowledge of statistics and mathematics to extract insights from data. Data science applies scientific methods, processes, systems and algorithms to dig out insights from data in structured and unstructured forms.

The professionals working on Data science apply machine learning algorithms to audio, images, numbers, text, video, etc. In this way artificial intelligence (AI) systems are created. Data Science assists to get data insights, makes it usable according to business requirements.




Data science amalgamates statistics, data analysis, machine learning and their related method for analysis of actual phenomena with data. Data science utilizes various tools to draw graphical representation to get knowledge about business progress.

To grab the increasing job opportunities in Data Science field, many people prefer to get knowledge of Data science. Many times, it is thought that Data Science and Data analysis are same. But both of their job roles are different. Even there is difference between data science and statistics.
The data science possesses many components such as Data Analysis, Machine Learning, Deep Learning, Data Visualization, Natural Language Processing (NLP) and Deep Learning, etc. The ‘Python’ and ‘R’ are highly used languages in Data Science. Their knowledge helps to find Quicker solutions during internship.

Data scientist carries out research and analysis on data. The data analysis done by the Data scientists is necessary for companies for trends’ prediction based on big data, business insights and growth prediction.

The Machine Learning & Data Visualization are the prominent components of both Data science & Artificial Intelligence as well. The practical implementation of algorithms which one has learnt theoretically in Machine Learning (ML) is essential for which one must work on some projects. Such person should practice implementation of algorithms on projects. Natural language processing is a branch of artificial intelligence. It mainly focuses on automated interpretation and generation of human language.

So, to learn all these components, the job-oriented data science training is very essential for the fresher as well as working professionals who want to do career either as a data scientist or in field of Data Science.

Selenium Web driver and IDE

Selenium is an open source testing Framework for web based applications and Desktop Applications as Well. It works based on Selenium Webdriver and IDE which reduces efforts to work on scripts.

Selenium provides interface to write test cases in a variety of languages like c#, Java, PHP, Python, Scala,etc and then we can run these test cases against any supported web browser.We provide Selenium Training in Pune. Selenium new demanded version is named as  selenium webdriver.

How is big data and Hadoop related?

The Bigdata and Hadoop are closely related. Big Data and Hadoop are related to one another, but both are not alike. Bigdata is a problem and Hadoop are solution of that problem.

Bigdata:

The Bigdata is nothing but huge amount of data. Big data is generally in terms of Petabytes and it even includes lots of data which comes daily. Big data possess regular entry of data like attendance record of employees in organizations and companies. It also keeps records of social network websites such as images, likes, videos and shares. It regularly keeps adding data to the already existing huge data. It is not so easy to store Big data in a single space as it would require lots of space.

Hadoop:

Before Hadoop the data was stored in traditional data storage system i.e., RDBMS. But RDBMS could store only structured data which added limitations to its efficiency. The vast scale unstructured data couldn’t be stored in RDBMS. So, Hadoop emerged as a solution to this problem. HDFS which is Hadoop’s storage layer can reliably store any kind of data on massive scale. It is helpful for the storage of increasing data. Hadoop stores all kinds of data and it stores tremendous data. Even it efficiently processes huge amount of data.

Means Hadoop splits and stores big data in multiple servers and when necessary fetch that data from those multiple servers and show them as a single one.

ETL Testing vs. Selenium Testing

Selenium IDE — Selenium IDE is a complete integrated development environment (IDE) for Selenium tests. It allows recording, editing, and debugging tests.

WebDriver — WebDriver is very successful then selenium remote control. Selenium Web Driver accepts commands and sends them to a browser.

API — As an alternative to writing tests in Selenium, tests can also be written in various programming languages. These tests then communicate with Selenium by calling methods in the Selenium Client API. Selenium now provides APIs for Java, C#, Ruby, JavaScript and Python.

There are lot of frameworks in selenium to work more easy Like testing, Maven, cucumber, Jenkins, Robot etc. Basically frameworks provide solution and functionalities to the particular problem.

ETL Testing — Basically ETL term refers to Extract data then transform data then load data. You can load or you can set no. of data in very short time period. ETL Testing is database testing by which you can test data which you are collecting from different clients by using Different Tools.

Informatica tool is using in ETL these days because Informtica is very good in result comparison to other tools. Informatica Workflow Monitor helps in easy, simple and quick job monitoring and recovery. There many components many content Technogeeks is providing in ETL testing with live projects like Introduction to ETL and DW Concepts, DATA WAREHOUSING LIFE CYCLE, SCD (Slowly Changing Dimensions), ETL Tool Implementation and Testing Concepts, Basic Concepts In Sql, Coding and testing process in different transformation rules, Testing Techniques in ETL, Informatica PowerCenter, Interview preparation, Interview questions and many more help to candidates.

Functions in Python

A function id a block of statement in which instruction is given to perform a particular task. It provides code reusability. They provide better modularity of the program. Python has a number of built in function and we can have user defined function also in it. Functions in Python, we have three parts:

1) Function Declaration

2) Definition

3) Calling

Functions in Python

Function declaration is done first before giving the code to be performed. There is some rule for function definition

1) There is a keyword def followed by the function name and ()

2) The argument and parameter are given in ()

3) Colon: will be used for indentation

4) The first statement of the function is an optional statement which the documentation string or the docstring

5) The return statement exit the function and the return without argument will be similar to return none

Function definition in Python Programming will be code which we have to run to get the required output. Function calling can be done in two ways

1) Call by value

2) Call by reference

TYPES OF FUNCTION with Few Functions Example:

1) Function with no argument and no return value

2) Function with no argument and with return value

3) Function with argument and no return value

4) Function with argument and with return value

Function Argument:

1) Keyworded

2) Default

3) Variable length argument

4) Required Argument

The Anonymous Functions:

These functions are called anonymous because they are not declared in the standard manner by using the def keyword. You can use the lambda keyword to create small anonymous functions. For more details visit Python Training Institutes in Pune.

Lambda forms can take any number of arguments but return just one value in the form of an expression. They cannot contain commands or multiple expressions.

An anonymous function cannot be a direct call to print because lambda requires an expression. Lambda functions have their own local namespace and cannot access variables other than those in their parameter list and those in the global namespace.

Although it appears that lambda's are a one-line version of a function, they are not equivalent to inline statements in C or C++, whose purpose is by passing function stack allocation during invocation for performance reasons.

Built-In Function in Python:

1) Print()-to print any value or anything on the screen

2) Abs()-Return the absolute value of a numeric value

3) Round()-Return the rounded value of a numeric value

4) Max()-return the largest item

5) Sorted()-it will sort in ascending order

6) Len()-give the number of element in the list or number of character of the string

7) Type()-give the type of variable

8) Zip()-create the tuples of variable

9) Chr()-return the string representing the character whose Unicode point is the integer given in ()

10) Filter()-Give an iterator for the element of inerrable for which the function give true

ETL & Selenium Training in Pune

Selenium Testing:

Selenium is one of the most popular and most widely used Automation tool. In another way you can say that anything which opens in web browser you can automate with Selenium. One of the reason for Selenium being widely used is open source which means it is available free of cost and there is no such hardware requirement. So you can start learning Selenium without any initial cost or without any initial setup. Another reason to stand Selenium in this growing market is as browser is getting advanced in the same way Selenium has also grown advanced which means that we can automate any browser which supports basic HTML or HTML5 or angular JS components or any advanced UI components. Using Selenium Webdriver makes automation much easy and you can go for any framework in any language (Java, C#, Ruby, Python etc.) and in any browser (Firefox, Chrome, IE, Safari). We in Technogeeks provide you Selenium Training in Pune, the complete learning of Selenium including all kinds of complex scenarios and also how to implement those in a framework.

ETL Testing:

As we are moving to the Digital world the data is growing at a much faster rate and so storing and retrieving the data process has to be smooth and as per the requirement. ETL provide the solution to store and retrieve data in structured and easy way. ETL stands for Extract-Transform-Load and it is a process of how data is loaded from the source system to the data warehouse. ETL Testing is done to ensure that the data that has been loaded from a source to the destination after business transformation is accurate. It also involves the verification of data at various middle stages that are being used between source and destination. While performing ETL testing, two documents that will always be used by an ETL tester are ETL Mapping sheets and DB Schema of Source, Target.
