Library Project: Business Rules

• First and last name must no more than 15 characters in length and must start with a capital letter.

• Street and City must be no more than 15 characters in length.

• Zip must be in format ##### or #####-####.

• Phone must be in format (###)###-####.

• Birth date must be within 18 years of the date to be considered a juvenile.

• All juveniles must have a sponsoring adult member .

• Each member can have no more than 4 items on loan at a time.

• If the item to be checked out is already on loan it must first be checked in.

• Check in/out must be confirmed.

Library Project: Phase I

• Introduction:

• In this project a windows based user interface was created for a library. The database and all backend code was provided.

• Project Goals:

• The goal is to create a Windows user interface to the provided library.

Library Phase I: .NET Skills

• Input validation/error providers

• Data binding a gridview control

• Regular expressions

• UI design

• n-tier architecture

Phase 1: Get Member

Shows get member page

when a valid member ID

with an item on loan is

entered.

Phase 1: Check Item In/Out

Checkout functionality is only available to

valid members who have less than 4 items

on loan. The above screen shows the

result of a checkout requested on an item

that is already checked out.

By entering an item that is checked out

and pressing the check in button the

following screen appears allowing the

librarian the ability to confirm or cancel the

check in.

Phase 1: Add Member

Shows the form to add an adult member

with invalid data to show some of the

validation controls in action.

Shows the form to add a juvenile member.

Invalid data is enter to show validation

handling and the birth date is selected to

show the datetimepicker control in action.

Library Project: Phase II

• Introduction:

• This project creates a data access tier using ADO.NET code and any stored procedures necessary to access and update the SQL Server database.

• Project Goals:

• To create the data access layer for the library.

Library Phase II: .NET Skills

• SQL Server

• ADO.NET

• Linq

• Stored Procedures

• Error handling

• Unit testing (stored procs)

Phase II: N-tier Architecture

Shows the n-tier

architecture of the library

project. The front-end calls

the business layer which

calls to the data access

layer through the data

access interface. Note that

all communication with the

database is done through

the data access layer.

Phase II: XSD and DBML Files

ADO.NET is used to

create an ItemsDataSet

to load data into the

items on loan grid view of

the Get Member page

LINQ to SQL was

used to get

information on all

items on loan that are

past due.

Phase II: Stored Procedures

Shows part of the stored proc

used to check an item out of

the library. Comments explain

what each piece of code does.

Phase II: ADO.NET Code

Shows ADO.NET

code for adding an

adult member to the

library.

Library Phase III

• Introduction:

• In this phase of the library project an ASP.NET web front end was created to make the library available online.

• Project Goals:

• The goal of this project is create a web front end in ASP.NET that works efficiently with the data access layer created in phase II.

Library Phase III: .NET Skills

• ASP.NET controls

• Master Pages/Content Pages

• AJAX Controls

• Cascading Style Sheets (CSS)

• Security (ASP.NET Configuration tool)

Library Phase III: Promote Juvenile

Shows the applications behavior when a

juvenile is promoted to an adult.

Shows the stored procedure that runs when a

juvenile is promoted to an adult.

Phase III: AJAX Controls

Shows the AJAX update

progress while the check in is

occurring on the AJAX update

panel.

Shows the markup code

necessary to add AJAX controls

to a page. Note that the script

manager is required on all

pages that contain AJAX

controls.

Phase III: ASP.NET Validation Controls

Shows the markup code

for the ASP.NET validator

controls.

Shows how validation is handled on

the web user interface when proper

information is not provided for adding

an adult. Similar validation techniques

were used on all pages in the

application.

Library Phase IV

• Introduction:• In this phase of the library project the ASP.NET

front end will be modified to use a WCF web service.

• Project Goals:• The goal of this project is create and host a WCF

service. The ASP.NET front end of the library should be able to use the service to make calls to the business layer.

Phase IV: Service Contract

Shows part of the

service contract used

to create the library

service.

Phase IV: Data Contract

Shows the Library

fault class used to

pass errors from the

service to the front

end.

Phase IV: Security

[PrincipalPermission(SecurityAction.Demand, Role="LibraryPartner")]

- The above principle permissions attribute was put on all methods of the service making them only accessible to members of the LibraryPartner role.

Final Project: XML Editor

• Introduction:• This project was a team project in which the team

worked to create a XML contract editor application for SetFocus that would eliminate the need for a Developer to make the changes every time a session needed to be added or a contract updated.

• Project Goals:• The goal of the application was to provide a UI that

would make the changes to the SetFocus files as needed using an n-tier architecture design and LINQ to XML to interact with the xml files.

Final Project: Add Session Page

Add session page shown

allows a session to be added

to the sessionConfig.xml file.

The code shows the LINQ to

XML code used to add the

session to the file.

Final Project: Update Session Page

Update session page allows

the starting and ending

dates of the session to be

changed. It also allows

sessions to be removed if

they have been cancelled.

The code shows the LINQ to

XML code for removing a

session.

Final Project: Edit Contract Page

The edit contract page

allows any xml file to be

edited directly on the page.

Variables can be added at

desired locations and

changes can be

saved/undone. The code

shows the data access

method used to update

changes to the contract.

What is SetFocus?

• The SetFocus .NET Master’s Program is an intensive, hands–on, project oriented program allowing knowledge and valuable experience putting the .NET skill set to use in a simulated work environment.

• I received over 500 hours of in-depths hands on experience focused on .NET Development.

• SetFocus projects are real world projects that are distributed just as I would receive in a position. I received project specifications and was expected to identify best courses of action with deadlines set for completion.
