In Python,objects are abstraction for data, and Python has an amazing variety of data structures that you can use to represent data, or combine them to create your own custom data. Before we delve into the specifics, I want you to be very clear about objects in Python, so let's talk ...

The process of creating Data Models using the syntax and environment of the Python programming language is called Data Modelling in Python. A Data Model is a data abstraction model that organizes different elements of data and standardizes the way they relate to one another and to the properties ...
Most traditional business intelligence (BI) solutions use this type of data warehouse. Alternatively, you can present the data through a low-latency NoSQL technology, such as HBase, or an interactive Hive database that provides a metadata abstraction over data files in the distributed data store...

Flink offers different levels of abstraction to develop streaming/batch applications. 最低级别的抽象只是提供有状态的流(stateful streaming)。它 通过Process Function嵌入到DataStream API 中。它允许用户自由处理来自一个或多个流的事件,并使用一致的容错状态。此外,用户可以注册事件时间和处理时间回调,允许程序实现...

forces you to think at a higher level of abstraction (All of which improve your programming skills and make the people who need to read your code happier!) Hooray, laziness! This is, of course, generated data from a uniform distribution, and we would thus not expect to see any significant...

Python has quickly become the most popular tool in this domain, owing much of its flexibility to its high-level of abstraction and impressively large and ever-growing set of libraries. Its accessibility has led to the development of popular and perfomant APIs, like pandas and scikit-learn, and...
