4 Important Definitions.NET Framework ASP Provides a common set of tools for developers on the Windows platform. Active Server Pages - a Microsoft technology that allows web pages to be dynamically generated. ASP.NET C# MSDE CSS SVN Newest version of ASP, with many significant improvements over classic ASP. Microsoft-created, object-oriented programming language similar to Java, with many features designed specifically for the.net Framework. Microsoft Desktop Engine Freely redistributable version of Microsoft SQL Server that integrates well with Windows and the.net Framework. Cascading Style Sheets - a simple format for attaching style information to HTML and XML documents. Subversion - a version control system for controlling access to a software project and it s files.

5 Acknowledgements Dr. Srinivas Aluru, for his support and guidance as the project advisor. Kate Bruns and the staff at the ISU Alumni Association, for guidance as well as origination of the project.

6 Problem Statement General Problem Statement ISUAA Online Store exists to promote the university and its alumni Current implementation is vastly outdated and inefficient Complete redesign of the storefront and new implementation of administrative tools is needed General Solution Approach New store and tool suite to be implemented by building upon existing C#, ASP, and.net knowledge. Careful focus on efficient database design and centralized control of administration

7 Operating Environment Served from existing Alumni Association server Windows 2000.NET framework MSDE database system Public and Administrative access from any modern web browser on the internet Internet Explorer, Netscape, etc.

8 Intended Users and Uses Intended Users Online Store Customers Alumni Association Staff Intended Uses Customers Browse catalog Purchase products Manage shopping cart Complete orders Administrators Add, remove, and update products Process orders View reports

9 Assumptions Technical Assumptions User is using a modern web browser User has access to a sufficient Internet connection Client server has sufficient system resources Client server has ASP.NET 1.1 (or later) installed Non-Technical Assumptions Users have previous experience with online stores Alumni Association staff have sufficient experience and ability to operate web-based administrative tools

10 Limitations Access to a dedicated database server Wanted to use server maintained by the ISU Foundation Technical difficulties prevented use of the server System resources available on client s server Team members proficiency with ASP.NET

11 End Product and Deliverables Online store capable of: Presenting merchandise Accepting orders Maintaining security New database that eliminates duplication of work Comprehensive suite of administrative tools to allow: Managing product catalog Easily processing customer orders Gathering store data

12 Project Activity Description Keith Dahlby

13 Present Accomplishments Online store with ability to: Browse product catalog Add items to a shopping cart Administrative interface to: Add categories to the catalog Add products to the catalog

14 Approaches Considered Programming Language: C# Official language supported by ASP.NET Many built in classes and functions Database: MSDE Integrates well with the operating system Many windows tools available Seamlessly integrates with ADO.NET Database: MySQL (not used) Robust, free, and widely supported Doesn t integrate as seamlessly Platform: Windows 2000 Windows best supports ASP.NET Existing server operating system, yet we suggest upgrading to Windows 2003 when possible Most of these approaches were design constraints from client

15 Project Definition Activities Requirements and technical considerations initially well-defined by client Detailed design questions resolved during project design, in consultation with client

16 Research Activities Database system Decision between MSDE and MySQL Considerations: Integration with Windows 2000 Server and ADO.NET Interface for database design and configuration Future upgrade path ASP.NET.NET Framework v2.0 Performance questions: Caching Efficient access to database

17 Design Activities Design Constraints Primary audience using modern web browser with sufficient bandwidth Internet Explorer 5.0 or later Netscape 6.0 or later Safari Mozilla Firefox Users with non-traditional or legacy web browsers require a functional user experience Web applications present inherent limitations on user experience System resources available on existing client server Limited to Windows 2000 Server running IIS and ASP.NET

18 Design Overview Design Activities (cont.) Presentation Tier (ASP.NET WebForms) Business Logic Tier (Business Components) Data Access Tier (Data Access Components) Database

19 Design Activities (cont.) Database Schema orders PK ID FK2 customer_id FK1 address_id_shipping FK3 address_id_billing date_ordered FK4 cc_id order_details PK ID FK1 order_id date_processed quantity FK2 item_id credit_cards PK ID number date_expiration FK1 cc_company_id customers PK ID name alumni_number FK1 contact_id ismember items PK ID FK1 vendor_id description price_nonmember price_member price_atcost FK2 statuscode_id ship_cost_unit ship_cost_base pref_picture_id pictures PK ID data FK1 item_id addresses PK ID address_1 address_2 city state zipcode vendors PK ID name contact_name FK1 address_id FK2 contact_id website_address statuscode PK ID message can_order categories PK ID name description FK1 featured_id item_categorization PK,FK1 category_id PK,FK2 item_id options PK ID string_xml item_options PK,FK2 item_id PK,FK1 option_id lineitem_options PK order_details_id PK,FK2 option_id choice credit_card_companies PK ID name contacts PK ID phone_home phone_work phone_mobile fax

20 Primary Use Case Design Activities (cont.) Default View Category View Item Add Item View Cart Checkout Confirm Receipt

21 Implementation Activities Item Options Problem: Custom fields for certain items Future items with unknown options Parameter choices affect price Changes: Options stored as serialized objects in database Organized items in the cart by item - Simplifies management of item options - Simplifies administrative metrics Objects Problem: Re-conceptualized object oriented structure needed to better fit presentation requirements Changes: Cart Object Picture Object CreditCard Object

22 Testing Activities Testing performed throughout development Test pages while creating new objects High-level custom web controls boundary conditions tested with sample pages Database tested with concurrent development of administrative interface pages Client testing and feedback Individual components released to staff members Problems exposed by non-dev users Feedback acquired Future testing Release private version of store to entire ISUAA staff Comprehensive testing/feedback on a larger scale

23 Other Significant Activities Alumni member login integration Lack of proprietary ASP.NET module to retrieve user information Unable to test member functionality Site redesign No styling information provided to group Unable to match appearance with other Alumni services Upcoming releases (could enhance implementation) SQL Server Express 2005 Visual Studio 2005 ASP.NET 2.0

39 Commercialization Commercialization for this product is not considered, as it is a specific customized upgrade to an existing system

40 Additional Recommendations Multiple product images Extended category structuring Frequent use of stored procedures Database backup/recreation script Windows Server 2003 upgrade Integration of administrative functionality with administration of other Alumni web applications

41 Lessons Learned What went well? Meetings with Alumni Association staff Good brainstorming, solid design Good scan of technology options, proved useful when original database was found to be inadequate What did not go well? Slow development early on Duplication of work due to changes in system

42 Lessons Learned (cont.) What technical knowledge was gained? New development skills with C# and ASP.NET Web-based development experience What non-technical knowledge was gained? Small team development interactions Long-term project planning What would be done differently? More discipline and vigilance in adhering to schedule

43 Risk and Risk Management Anticipated potential risks Loss or corruption of code SVN Breakdown of communication Recurring scheduled meetings and direct contact info Anticipated risks encountered Second semester communication and missed meetings meeting info, and other avenues of communication Unanticipated risks encountered Restricted access to ISU network from off-campus VPN software set up Resultant changes due to unanticipated risks Use of VPN software, moving to campus location otherwise
