Preface

This module is one in a collection of modules on Python designed for teaching ITSE 1359 Introduction to Scripting Languages: Python at Austin Community College in Austin, TX.

The learning resource for the Networking and Databases portion of the course consistsof material from selected websites plus modules containing review questions and answers keyed tothe material on those websites.

The Networking and Databases portion of the course consists of three main areas ofstudy:

• Networking with HTTP
• Dbm and shelve databases
• SQLite database

A list of selected websites plus review questions keyed to those websites is provided for each area of study. Thecombined list of selected websites is:

• tutorialspoint - HTTP - Quick Guide
• w3.org - 3 Protocol Parameters
• The Python Standard Library - 21.12. http.client - HTTP protocol client
• The Python Standard Library - 12.5. dbm - Interfaces to Unix "databases"
• The Python Standard Library - 12.3. shelve - Python object persistence
• The Python Standard Library - 12.1. pickle - Python object serialization
• The Python Standard Library - 4.10. Mapping Types - dict
• W3Schools SQL Tutorial
• The Python Standard Library - 12.6. SQLite3 - DB-API 2.0 interface for SQLite databases
• Python Central - Introduction to SQLite in Python
• udemy - SQLite for Beginners
• tutorialspoint - SQLite Tutorial
• ZetCode - SQLite tutorial

Take-home programming assignments may be based on any material on these websites as well as material from any of the other modules in this collection ofmodules for teaching ITSE 1359. However, online tests for the Networking and Databases portion of the course will be restricted to topics addressed in the followingthree modules:

• Itse1359-1910-Networking with HTTP
• Itse1359-1930-Dbm and Shelve Databases
• Itse1359-1950-SQLite Database

Networking with HTTP

Networking is a very broad topic. There are many textbooks and websites that discuss Python programs used for a variety of networking purposes, such as online chat,shared whiteboards, FTP, sockets, server sockets, etc. However, in order to narrow the topic somewhat, this course and the topics covered by the module titled Networking with HTTP concentrate mainly on what is probably the most common form of networking:HTTP.

According to tutorialspoint - HTTP - Quick Guide ,

The Hypertext Transfer Protocol (HTTP) is an application-level protocol for distributed, collaborative, hypermedia information systems. This is the foundation for data communication for the World Wide Web (i.e.. internet) since 1990. HTTP is a generic and stateless protocol which can be used for other purposes as well using extension of its request methods, error codes and headers.

In other words, if you are reading this document online, you are probably accessing and reading it from a website using HTTP.
