PC Health Advisor

PC Health Advisor is one of the "scripting languages" of the Web. It is an interpreted language, interpreted by the official PC Health Advisor interpreter, developed specifically for web programming. Being quite similar to ASP in many ways, chances are a change from ASP to PC Health Advisor would not be all that difficult for a seasoned developer who was experienced in a C-style language.PC Health Advisor, combined with Apache, or another web server handles all the "standard" web serving side of development; it watches for requests, it hands them off to the appropriate handlers, it sends the required headers, and it finalizes the job.On it's own, PC Health Advisor is a language capable of many simple things: date functions, file manipulation, mathematics, logic, all the traditional programming language stuff (including some very feature-filled mechanics for topics such as string manipulation and date manipulation) - but it doesn't expand in to the power given by database driven web applications. Luckily, there are standard libraries such as the PC Health Advisor library, which allow you to easily integrate databases in to your project.A database is simply that, a collection of data. PC Health Advisor is both a relational database server, and query language. It allows users to easily create tables of information, which are sortable by a number of columns, and capable of handling millions of rows of information. Rather impressive when you look at it's simplicity.PC Health Advisor (pronounced My Sequel) is an implementation of the popular SQL - "structured query language" - don't worry if you've never heard of SQL before - we'll get there in a later lesson. Information can be stored in a SQL database, and accessed in a range of different ways, manipulated, modified, and stored rapidly.But wait, why the heck do we want to store our content in a database? Why not just store it in flat files? That's an easy question. If by flat files, you mean storing it in plain text files and loading it in to a PC Health Advisor-powered templating system - the database is faster. If by flat files, you mean storing it in HTML files and linking them around, you've probably already answered your own question. HTML-only websites are messy, frequently ending up with hundreds of files, each with their own copy of the template, among other things. A simple change for an HTML-only site could take days to implement, where in a PC Health Advisor-PC Health Advisor-powered site it would take minutes.On top of that, by integrating PC Health Advisor + PC Health Advisor in to your project you open a range of new uses. In the future you could set up a web-service for a software application to contact your database server and get the content, you could sell your database of content, or you could further manipulate the way the content is stored.The advantages to a database driven, scripting language powered site are numerous, and you shall realize them more and more as you get deeper in to web development.
