This hands-on Introduction to Big Data training provides a unique approach to help you act on data for real business gain. The focus is not on what a tool can do, but on what you can do with the output from the tool.
They are the workhorse abstraction in Great Expectations, covering all kinds of common data issues. Expectations are declarative, flexible and extensible. They provide a rich vocabulary for data quality. Many data teams struggle to maintain up-to-date data documentation.
Big data refers to extremely large data sets. In the modern economy, it is common for companies to collect large volumes of data throughout the course of conducting their business operations. When used correctly, big data can be highly beneficial for organizations to help them improve efficiency, profitability, and scalability.
Run your data through one of Great Expectations' data profilers and it will automatically generate Expectations and data documentation. Profiling provides the double benefit of helping you explore data faster, and capturing knowledge for future documentation and testing.
'Discrete Mathematics', 'Data Structures and Algorithms', 'Database', and 'Machine Learning'. Except for Machine Learning, all other courses are fundamental courses.

Programming. While traditional Data Analysts might be able to get away without being a full-fledged programmer, a Big Data Analyst needs to be very comfortable with coding. ... Data Warehousing. ... Computational frameworks. ... Quantitative Aptitude and Statistics. ... Business Knowledge. ... Data Visualization.
One can easily learn and code on new big data technologies by just deep diving into any of the Apache projects and other big data software offerings. The challenge with this is that we are not robots and cannot learn everything. It is very difficult to master every tool, technology or programming language.
Broadly, there are two types of data analytics courses that you can take up for learning data analytics: traditional degree courses and online programs. Let’s explore each of them now.
Data Analyst Skills: Technical. Your technical skills will get you shortlisted for interviews. They are the first thing you need to tackle in order to succeed. Let’s first look at the technical skills you need.
As a data analyst, you will use a database languages such as SQL, to record, delete, organise, relate or alter databases where the information is held. You need to be comfortable enough with SQL to run queries and connect data points. The below video is your comprehensive guide to learn SQL.
A data analyst is not merely a skilful numbers person. In fact, deftness with ‘analytics’ is just a means to an end. A data analyst must be able to communicate effectively and persuade their audience by simplifying and sharpening the message, freeing it from jargon and emphasising on how the results can specifically improve business.
Viewing data sceptically also helps correct inconsistencies. As a data analyst, critical thinking skills are fundamental to doing your job well.
Data analytics is a practical field. If you are knowledgeable about the concepts, you’re good to apply them to solve real-world problems. The only way you can demonstrate hands-on experience is through a portfolio. While exploring data analytics courses:
Great Expectations is a shared, open standard for data quality. It helps data teams eliminate pipeline debt, through data testing, documentation, and profiling.
Expectations are assertions for data. They are the workhorse abstraction in Great Expectations, covering all kinds of common data issues.
Many data teams struggle to maintain up-to-date data documentation. Great Expectations solves this problem by rendering Expectations directly into clean, human-readable documentation. Since docs are rendered from tests, and tests are run against new data as it arrives, your documentation is guaranteed to never go stale.
Wouldn't it be great if your tests could write themselves? Run your data through one of Great Expectations' data profilers and it will automatically generate Expectations and data documentation.
Expectations are a great start, but it takes more to get to production-ready data validation.
Every component of the framework is designed to be extensible: Expectations, storage, profilers, renderers for documentation, actions taken after validation, etc. This design choice gives a lot of creative freedom to developers working with Great Expectations.
