Introduction to ETL and Data Warehouse Concepts

The ETL tool executes ETL strategy. The ‘ETL’ stands for “Extract, Transform, and Load”. ETL is generally connected with Data Warehousing ventures. Big organizations always need to move application data starting with multiple source systems to common data warehouse.

Example of source systems: ERP, Databases, File systems, Salesforce, Mainframes, etc.

Example of source systems: ERP, Databases, File systems, Salesforce, Mainframes, etc.

Example of target system / Data warehouse: Teradata, Hadoop, etc.

There are abundant sources for ETL to extract data. This data is then transformed into a mode and from there it is loaded into a data warehouse. There is high a demand in market for professionals who are efficient in this process. Even most of the professionals working on other testing technologies are switching to ETL testing. Hence it is important to gain knowledge about ETL testing along with skills. This requires proper guidance. So when you want ETL training in Pune, you should go for a leader in this domain who is Komal Arora who conducts training in institute Technogeeks, Pune, Maharashtra.

Technogeeks offers Classroom, hands on training. The course is Practically Oriented. The real time examples are given to candidates. It helps candidates to develop skills to apply their theoretical and practical knowledge in projects.

The trainers are working professionals in IT companies. They do personal assessment of every candidate and mentor every candidate personally.

Introduction to ETL and DW Concepts

• What is Data Warehousing?
• Differences : OLTP and Data Warehousing
• Why we need two separate solution for real time and warehouse
• EXTRACTION, TRANSFORMATION, and LOADING of data

Data Marts

• Need and usage of data marts and types of data marts
• Dependent DM & Independent DM

DATA WAREHOUSING LIFE CYCLE

Types of Tables:

• Fact Table
• Dimension table

Schemas:

Fact Table, Star Schema, Snowflake Schema, Fact Constellation Schema

Informatica PowerCenter Tool

• Administrator Module
• Advance Workflow Module
• Command Reference
• Designer Module
• Performance Tuning
• Transformation Modules
• Repository Modules
• Transformation Language Reference

SCD (Slowly Changing Dimensions)

Different types of SCD’s which developer develops and a tester has to test as per different types of data needs of clients.

We implement SCD-1 and SCD-2 in class to show the implementation part more transparently and explain SCD-3 to define how to work on limited historical data as well which is used sometimes.

ETL Tool Implementation and Testing Concepts

Basic Concepts of SQL (Select, Update, Insert, Delete, types of joins, nested query, etc.)

How to design frequently used testing queries to validate the data in source and target for both of the reasons Data Quality and Correctness to ensure that expected data came into the final and mediator target tables or not.

ETL Tool Architecture

• How ETL tool works and what is the basic need of ETL tools in the market
• Similarities between ETL tools and SQL
• Why we use ETL Tools if SQL is the only standard which any Database or Data Warehouse can use
• How ETL Tools work at back end
• Different ETL Tools
• What types of tasks tester performs on ETL for testing purpose

Coding and testing process in different transformation rules

• SAMPLE Loading from source to target
• Transformation of – SORTER, FILTER, EXPRESSION, JOINER, UNION, AGGREAGATOR, SEQUENCE GENERATOR, SQL.

We provide this practice as additional benefit to you so that you can implement jobs by yourself to understand that what developers do in real time which you have to test.

Testing Techniques in ETL

• MINUS Query
• COUNT Query
• UNION Query
• JOIN Query

Other benefits:

• Interview Questions
• Resume preparations
• Live Project
• Assignments
• Real-time Scenarios examples and solution discussion

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.
