Business Applications

• 3. Multiple platforms
• Non web-based applications
• Ex. Windows-based
• Web-based applications
• Non mobile applications
• Mobile applications
• Cloud-based applications
• Integrated applications

Business Applications

• 4. Component and service oriented architecture
• Component-based software development focuses on
  building large software systems by integrating
  previously-existing software components.
• A service-oriented architecture is an information
  technology approach or strategy in which
  applications make use of services available, such
  as web services.

Business Applications

• 5. Object-oriented, GUI, event-driven

Impacts of Cloud Computing on Application
Development

• Website hosting
• Platform as a service
• the consumer creates an application or service
  using tools and/or libraries from the provider.
• Infrastructure as a service
• it provides access to computing resource in a
  virtual machine
• Big Data management
• NoSQL database Not Only SQL

Windows Azure

• http//azure.microsoft.com/en-us/
• Features link

Course Objective

• Develop database-centric, multiple platforms,
  component and service oriented business
  applications with .Net and Windows Azure.

Common Language Runtime
11

• Common Language Runtime
• Manages execution of compiled .NET program.
• Provides .Net basic services, such as memory
  management, garbage collection, etc.
• Base Class library define all the basic data
  types such as system.object, numeric, date, etc.
• Data and XML Classes work with database
  (ADO.NET) and XML document.
• ASP.Net and Forms Classes that generate user
  interface.
• CLS CLS dictates the minimum group of features
  that a .Net language must have.

12
Execution of a .Net Program

• Language must compliance with Common Language
  Specification, CLS.
• Compile the language into Microsoft Intermediate
  Language (MSIL) code.
• The MSIL code is then executed in the Common
  Language Runtime (CLR), which conceptually is
  same as the Java Virtual Machine, where it is
  translated into machine code by a compiler.
• It is a server-side technology.

13
.Net Advantages

• It is independence from a specific language.
• Developers can create a .Net application in any
  .Net compatible language.
• .Net moves most of the functionality from the
  language to the .Net Framework. All .Net
  languages can use these classes.
• It can exist on multiple platforms
• Windows, Web, Mobile devices, cloud computing
• Facilitate application development
• Tools, wizards
• Universal data access Data can be accessed by
  any Internet-connected device.
• ADO.Net
• Implement latest development technologies.
• AJAX, web service, Model/View/Cobtroller, etc.
• Cloud computing
• Big Data

14
Programming in the .Net Framework

• Programming in the .Net Framework means making
  use of the classes, objects, and members exposed
  by the Framework, building your own classes on
  top of these and manipulating the resulting
  objects using a .Net language.

Hands On Techniques

• C
• Interface and event-driven programming
• Class and component programming
• Database programming
• Embedded SQL with MS SQL Server
• ADO.NET programming model
• NoSQL
• Web Techniques
• Server side scripting ASP.NET
• ASP.Net and ADO.Net
• Cloud computing with Windows Azure

16

  2013)
• Windows Azure system development kit for .Net
