This document discusses the technology requirements and installation approaches for web applications. It outlines the key components needed which include an operating system, web server, database management system, and application software. It also describes two common installation approaches - using a local server by installing all components on one's own PC, or using a remote server by hosting with an external company.

Learning Objectives In this chapter, you will learn: • Technology requirements for Web Application – Operating System – Web Server – Database Management System – Application software • Installation Approaches – Local server – Remote Server © Cengage Learning 2015 1
Web Technologies • Operating Systems – software that manages computer hardware and software resources and provides common services for computer programs. – Example: Windows, Mac, Linux, Unix • Web Server – either the hardware (the computer) or the software (the computer application) that helps to deliver web content that can be accessed through the Internet. – Example: Apache, Windows IIS, Nginx, GWS © Cengage Learning 2015 2
Web Technologies • Database Management System – software system designed to allow the definition, creation, querying, update, and administration of databases. – Example: MySQL, PostgreSQL, Microsoft SQL server • Application Server – software framework that provides a generalized approach to creating an application-server implementation, regard to what the application functions are, or the server portion of a specific implementation instance. – Example: Tomcat, PHP, .NET © Cengage Learning 2015 3
Web Application Installation approaches • Local Server – Installing Web Server, DBMS, and application server in one’s PC – Advantage: Great for development and testing , full control over server configurations – Disadvantage: Transferring files from local to the server, changing configuration © Cengage Learning 2015 4
Web Application Installation approaches • Remote Server – Hosting company that has web technologies set up and running 24/7 – Advantage avoided installing software on your pc, eliminate transferring from local to remote – Disadvantage Risk the accessibility and health of the website, © Cengage Learning 2015 5
