Here are the key points about Apex classes: - Apex is an object-oriented, cloud-based programming language that allows developers to execute flow and transaction control statements on the Force.com platform - Apex code can be used to define classes, interfaces, exceptions, and triggers to manipulate data in Force.com - Apex classes can define methods, variables, constructors, and more to encapsulate reusable logic - Apex classes have access to the Force.com platform's data, metadata, APIs and more to build robust business logic and applications - Apex is compiled to bytecode and executed securely in Salesforce's multitenant architecture So in summary, Apex allows developers to

Editor's Notes
- #4 Can you guess the word? This is the theme for the day. Social and interactive. This is not a one way conversation. That wouldn’t be very social would it?Emphasize that questions can be asked about anything, it doesn’t require to be related to the tutorials, etc. It’s an open dialog.
- #6 OK, we have a lot to talk about today. It might seem a little overwhelming, but let’s focus on the big topics.
- #12 Disruptive changes require fast and agile development
- #13 Enterprises are responding to this demand by going to the cloud
- #37 Let’s have an exercise in requirements gathering. Here is some of the core needs for our Warehouse application. What nouns here should we be looking at to model our data with?
- #38 Let’s have an exercise in requirements gathering. Here is some of the core needs for our Warehouse application. What nouns here should we be looking at to model our data with?
- #39 Let’s have an exercise in requirements gathering. Here is some of the core needs for our Warehouse application. What nouns here should we be looking at to model our data with?
- #40 Here is an overview of what our data model will look like. Recommended: Break into a demo of building data in the browser, either custom object wizard or schema builder depending on audience/workbooks
- #44 Relational DataValidated dataProcess driven workflowsApproval SystemField AuditingUsers, Profiles and PermissionsEnterprise Collaboration
- #46 Formulas are the building blocks of creating our business logic declaratively, and you’ll see them appear again throughout the day.
- #47 Formula fields work like formulas work in Excel spreadsheets.The formula here insists that a delivery date is needed for these stages.
- #48 Validation rules are always in 3 parts IF->then-ERROR.Let’s have a look how this is implemented in Force.com - flip to the app now and check out the check_inventory rule on LineItem
- #49 This is hard to see
- #50 Automated, time based processes that can integrate into backend systemsGreat for consistency, and removing human involvementEg:
- #55 How does privacy work with Chatter? Can you accidentally share a record I’m not supposed to see?
- #56 We’re going to look at Visualforce later, but let’s have a bit of a preview here. Visualforce is our user interface framework in the cloud, and it knows all about Chatter.
- #57 Want to make Chatter smarter? You can extend it with Apex Triggers to associate highly custom behaviors. Here if someone adds a hash tag “promote”, Apex will automatically add it to the promotion and even update the record to let everyone know it just did that. We’ll also be doing a deeper dive into Apex and triggers today as well.
- #62 Let’s talk about anatomy, specifically the anatomy of an application. If you are going to build something which is easy to maintain in an enterprise setting, how would you do it? What would be the bones, muscle and skin of your application?
- #63 The MVC pattern is one of the most commonly used design paradigms to create enterprise web applications. It neatly divides and conquers the application into distinct components to solve specific problems.
- #64 Specifically it keeps your data, your logic and your interfaces distinct while allowing them to interoperate. Think of your data like the bones of an animal – it defines the structure of what that animal will be, but it doesn’t need to know how to move around. Logic, your muscle, will do that for it. But Logic isn’t worried about appearances – that’s what your interfaces … the skin of your application … is for.
- #65 On the Force.com platform, we give all the tools to get this done. You’ve already seen custom objects, now let’s look into what makes that work with Apex and Visualforce to give your applications logic and a UI.
- #66 So we know how to get our data. What can we do with it? With Apex, it might be easier to ask what you can’t do with it.
- #67 For those unfamiliar with OO, here’s what a simple class structure looks like.NOTE: If you’re using this slide deck for a very technical audience, breeze through this section and get to meatier features of Apex.
- #69 Let’s have a look at what Apex looks like. We are going to build the worlds most simple Apex Class, HelloContacts. This is a great example for seeing how we can use the new Developer console within Force.com to code completely in the cloud. Much of the workbook will talk about use the Force.com IDE, an eclipse-based development environment. For today however, we are going to use the developer console. Talk through dev console with the repository view, highlight SOQL (we are going to need that to achieve our requirements) then execute the class and show how to use the log viewer to see execution time etc.
- #70 OK. We can do all of this powerful logic, right in our cloud – right from your web browser. It seems just too easy, right?There’s a catch. Think about an airport, and all the planes that are flying in the airspace and their trajectories and where they are heading and where they are going. Imagine being a pilot in that situation trying to land without an air traffic control tower.Force.com is an enterprise class multitenant architecture. We have a lot of planes in the air, and they all have places to go – but we get them where they are going, we do it safely and securely, and we’re doing it faster and faster with every release. We do this with some pretty excellent technology, but we also put some limits on what some of the our technologies like Apex can do. This makes sure someone isn’t able to fly a big, huge jet really quickly right through the middle of everyone’s path.
- #71 So what are some of those things?
- #72 OK, we have our bones and our muscle – what about our skin?
- #73 For those unfamiliar with OO, here’s what a simple class structure looks like.NOTE: If you’re using this slide deck for a very technical audience, breeze through this section and get to meatier features of Apex.
