Databases are an essential aspect of modern life. Most businesses could not function without them, and they are the backbone of popular Internet services such as Apple Music, Facebook, Twitter, and eBay. Section A begins the module with an overview of databases and the many ways they are used today. What is a database? In its broadest definition, a database is a collection of information. Today, most databases are stored as computer files. A database can be a simple list of names and email addresses, or it can be a much more extensive compilation of data, such as Google’s collection of user queries. Databases can even incorporate several lists. For example, the database for an ecommerce site, such as Amazon.com, includes inventory lists and customer lists. Databases are created and managed by individuals and organizations. The tasks associated with creating, maintaining, and accessing the information in databases are referred to as data management, file management, or database management.
What’s the scope of computer programming? Computer programming encompasses a broad set of activities that include planning, writing, testing, and documenting. Most computer programmers participate to some extent in all of these phases of program development, but they focus on writing statements that computers follow to perform tasks. A related activity, software engineering, is a development process that uses mathematical, engineering, and management techniques to reduce the cost and complexity of a computer program while increasing its reliability and modifiability. Software engineering can be characterized as more formalized and rigorous than computer programming. It is used on large software projects where cost overruns and software errors might have disastrous consequences.
What is Python? In this module, you will learn to use the Python programming language. Python was first released by its designer, Guido Van Rossum, in 1991. It was named not after a large snake, but after the British comedy television series Monty Python’s Flying Circus. Python is excellent for beginners, yet outstanding for experts. It is a language that is relatively easy to learn, but still powerful enough to be useful for solving real-life problems. There are several versions of Python, including versions 2 and 3. You will be using version 3 in this module.
