It's common to require entities and create, read, update, and delete (CRUD) operations functions to efficiently perform Amazon DynamoDB database operations. PynamoDB is a Python-based interface that supports Python 3. It also provides features such as such as support for Amazon DynamoDB transactions, automatic attribute value serialization and deserialization, and compatibility with common Python frameworks, such as Flask and Django. This pattern helps developers working with Python and DynamoDB by providing a library that streamlines the automatic creation of PynamoDB models and CRUD operation functions. While it generates essential CRUD functions for database tables, it can also reverse engineer PynamoDB models and CRUD functions from Amazon DynamoDB tables. This pattern is designed to simplify database operations by using a Python-based application.
