The document discusses the MEAN stack, which consists of MongoDB, Express, AngularJS, and Node.js. It begins with an agenda that outlines discussing a new way for web applications with MEAN and demonstrating it. It then provides a history of web development from mainframes to client-server models to today's single page applications. The rest of the document demonstrates setting up and using each component of the MEAN stack to build a sample web application, highlighting the advantages of having a consistent JavaScript-based full stack. It concludes by taking questions and providing additional resources on MEAN stack development.

1990- 2000
 In the 90’s, systems should be client-server

5. 5
2000 - 2015
 Enterprise applications use the
multi-tier model

6. 6
Three ways for web
application
 Application server products can be separated into 3
categories:
 J2EE-based solutions
 Non-J2EE solutions (PHP, ColdFusion, Perl, etc.)
 And the Microsoft solution (ASP/COM and now .NET with
ASP.NET, VB.NET, C#, etc.)

Web Development Trends
For 2015 And Beyond
 More User Experience
 Mobile First Strategy
 RESTful API
 Single Page Application
 MVC pattern on client and server
 Cloud
 Java and .NET survive on larger enterprise app
 Javascript and GO language are next language after
Java
