Title: ISYS 512 Business Application Design and Development with .Net


1
ISYS 512Business Application Design and
Development with .Net
  • David Chao

2
Business Applications
  • 1. Database-centric applications
  • Examples
  • Login to a website
  • Join a website to become a member
  • Online shopping

3
Business Applications
  • 2. Client/Server structure
  • a. Presentation user interface
  • Menus, forms, reports, etc
  • b. Processing logic
  • Business rules
  • c. Database

SQL queries

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

5
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.

6
Business Applications
  • 5. Object-oriented, GUI, event-driven

7
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

8
Windows Azure
  • http//azure.microsoft.com/en-us/
  • Features link

9
Course Objective
  • Develop database-centric, multiple platforms,
    component and service oriented business
    applications with .Net and Windows Azure.

C
Common Language Specification
ASP.Net
Windows Forms
Data and XML
Base Class Library
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.

15
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
Required Software
  • Visual Studio 2013 Professional
  • MS SQL Server Express LocalDB (installed with VS
    2013)
  • Windows Azure system development kit for .Net

17
Download and Install VS 2013 Professional
  • Microsoft DreamSpark website
