Which is the best popular technologies for web development?
CLIENT-SIDE


- HTML and xHTML - extremely easy


- XML - extremely easy


- Javascript - takes some time to learn but easy after you master the syntax, similar syntax to PHP, Java, etc.


- Cascading Styel Sheets (CSS) - easy


- AJAX - combination of Javascript and XML, must have a solid understanding of Javascript





SERVER-SIDE


- PHP (open-source) - somewhat easy to learn


- Adobe ColdFusion - very easy to learn


- Microsoft ASP.Net - must know how to program in Visual Basic.Net or C# (very similar to Java)


- Ruby on Rails


- Python


- Java (JSP) - not a lot of developers coding in this language outside of enterprises, the syntax is similar to C# and PHP but it has a very powerful API and can be resource (server) intensive





DATABASE


- SQL - fairly easy...but pretty much a must with any server-side language


- Oracle - very similar to SQL with some subtle differences

Reply:The free and most easiest to learn is PHP/MySQL.


The more sofisticated one + more costly .NET


The most powerfull but could be too powerful is JSP.
