Overview of this book

Data analysis enables you to generate value from small and big data by discovering new patterns and trends, and Python is one of the most popular tools for analyzing a wide variety of data. With this book, you’ll get up and running using Python for data analysis by exploring the different phases and methodologies used in data analysis and learning how to use modern libraries from the Python ecosystem to create efficient data pipelines. Starting with the essential statistical and data analysis fundamentals using Python, you’ll perform complex data analysis and modeling, data manipulation, data cleaning, and data visualization using easy-to-follow examples. You’ll then understand how to conduct time series analysis and signal processing using ARMA models. As you advance, you’ll get to grips with smart processing and data analytics using machine learning algorithms such as regression, classification, Principal Component Analysis (PCA), and clustering. In the concluding chapters, you’ll work on real-world examples to analyze textual and image data using natural language processing (NLP) and image analytics techniques, respectively. Finally, the book will demonstrate parallel computing using Dask. By the end of this data analysis book, you’ll be equipped with the skills you need to prepare data for analysis and create meaningful data visualizations for forecasting values from data.

Reading and writing data from MongoDB

MongoDB is a document-oriented non-relational (NoSQL) database. It uses JSON-like notation, BSON (Binary Object Notation) to store the data. MongoDB offers the following features:

  • It is a free, open-source, and cross-platform database software.
  • It is easy to learn, can build faster applications, supports flexible schemas, handles diverse data types, and has the capability to scale in a distributed environment.
  • It works on concepts of documents.
  • It has a database, collection, document, field, and primary key.

We can read and write data in Python from MongoDB using the pymongo connector. For this connectivity purpose, we need to install MongoDB and the pymongo connector. You can download MongoDB from its official web portal: PyMongo is a pure Python MongoDB client library that can be installed using pip:

pip install pymongo

Let's try database connectivity using pymongo:

# Import pymongo
