The JavaScript reference serves as a repository of facts about the JavaScript language. The entire language is described here in detail. As you write JavaScript code, you'll refer to these pages often (thus the title "JavaScript reference").
Modern JavaScript Tutorial: simple, but detailed explanations with examples and tasks, including: closures, document and events, object oriented programming and more.
The Internet has become a critical part of almost every part of our society — it provides information, communication, and entertainment to billions of people every day, and enables coordination and collaboration between people and business across the globe.

Without the Data Model and tools like Talend, data can completely fail to provide business value, or worse impede its success through inaccuracy, misuse, or misunderstanding.
Data Modeling - Relational Databases (SQL) vs Data Lake (File Based) - Confessions of a Data Guy

Monitor data quality in your data lake using PyDeequ and AWS Glue | AWS Big Data Blog
In our previous post, we introduced PyDeequ, an open-source Python wrapper over Deequ, which enables you to write unit tests on your data to ensure data quality. The use case we ran through was on static, historical data, but most datasets are dynamic, so how can you quantify how your data is changing and detect […]
