Modesto Bank ProjectSystems Analysis & Design
By: Brandon Miller, Wenjie Li, Jae-Eun (Jane) Russell, & Subathra Aravamudhan
Project Background
• We were to imagine that we were experienced consultants asked to develop a banking system
• Professor Burer acted as the “client”
• Project began on 2/4/03
Project Background: Time Table
• Divided into 4 milestones (stages):• Milestone 1: Plan
Due 2/18/03
• Milestone 2: Analyze Due 3/11/03
• Milestone 3: Design Due 4/15/03
• Milestone 4: Implement Due 5/8/03
Milestone 1: Requirements• Completed in 17.5 hours
• Create a System Request
• Draw up an Executive Summary
• Design a Work Plan
• Create Project Charter
• Create a Risk Analysis
• Prepare Economic Feasibility Analysis
• Design an Internal Project Website
Milestone 1: System Request
• Page 5 of Project Documentation
• Sections• Business Need
• Functionality & Scope
• Expected Value
• Special Issues & Constraints
System Request: Business NeedTo increase efficiency and customer service through
the development of a user-friendly, web-based banking information system, which will:
• Allow for maintenance of a centralized database for the managers of Modesto Bank
• Function through an interactive user-friendly website with entry, update, add, and delete options
• Deliver the most recent product information to all managers and officers of Modesto Bank via the internet
System Request: Functionality & Scope
The system (website & database) will have the following functionalities:• Equipped to handle four different types of products, namely:
• Money market products.• Credit card products.• Mortgage products.• Certificate of deposit products.
• Enabled to allow the bank managers to make changes in the products.• Permits multiple users to be able to access the database at any given
time• Secured website interface that will allow easy navigation of various
parts of the site after confirming the login ID and password.• Update/add/delete functionalities to edit the fields in the database to
allow for the most recent information about the products.
System Request: Expected Value
Tangible:• Increased customer service by being able to provide the customer
with the most up-to-date information. Rates will be updated in the timeliest fashion.
• Reduction of paper by not having to print and distribute weekly product rate specification sheets
Intangible:• Recognition of Modesto Bank as a forerunner for incorporating
information technology in their central database.• Increased work efficiency among managers and other top officials• Less possibility for distortion of product information among the
various branches of the bank and the central bank.
Executive Summary
• Page 7 of the Project Documentation
• Mission Statement:• The mission of this project is to provide the
highest quality of information and support in promoting sensitive information transfer among the various managers through the internet of the Modesto Bank.
Executive Summary GoalsLogin and security standards
• A login and password prompt would be built in the “To be” system to help ensure the security of the site
• Only certain managers are allowed to update the fields
• If time permits, the team will use cookies for session security
Executive Summary Goals
Table Standards:
• All the tables would be normalized up to the third normal form
• All the products have fields that can be updated by some of the senior managers of the bank. Products may also be added.
• The tables do not give permission for any fields in the various products to be deleted
Executive Summary Goals
Website Standards:
• A easily navigable and user-friendly website would be developed
• The site would be empowered to carry on the querying and reporting capabilities.
• The site would be enabled to grow with the company’s expansion.

Requirements Specification• Page 16 of Project Documentation• Salient Features of the New System:
• The system will satisfy the increased need for high speed & efficient information transfer among the different branches of the Modesto Bank
• The system will be enabled to allow multiple people to view different fields of the products at the same time.
• Even though the system will allow multiple users, only a few of the senior managers will be given higher privileges like updating and adding data in the fields.
• Any change in the database will immediately be reflected on the website.
• Easy navigation throughout the site to different products offered by the bank.

ERD: Example Table
The Credit Card Products will include the following fields that can be adjusted and viewed by the managers of the Modesto Bank:Product ID*- The field used to uniquely identify the products.Type –The different types of credit cards offered by the bank, which include the Classic, Student and Platinum cards.APR- The annual percentage rate charged for balance on the cards.Maximum Credit Limit- The maximum credit limit offered on the different products.Eligible for Rewards Program (Boolean) - Expresses whether the card is eligible for the rewards program.Initial Offering – The date the product becomes available. Expiration Date – The date of expiration on the product card.
ERD: User TablesThe Access Rights table includes the following features: Rights_ID*- The field used to uniquely identify the right.Add – Right for adding data (It indicates with y/n)Update – Right for updating data (It indicates with y/n).View – right for viewing data (It indicates with y/n).
The Users table includes the following adjustable features: Username*- The field used to uniquely identify the users.Password – The field entered by each userFirst_name – Users’ first nameLast_name – Users’ last nameDepartment – Users’ departmentPosition – Users’ positionRights_ID – The field that is defined rights for each user.
Milestone 3: Requirements
• Completed in 32 hours• Implement our ERD in MySQL
• Make Program Specifications
• Design an HTML Prototype
ERD Implementation
• Done using phpAdmin for MySQL
• See the interface by clicking
Program Specifications Example
1. Insert a new mortgage productSQL Command:
INSERT INTO `mortgage` ( `ProductID` , `MG_Fixed` , `MG_Duration` , `MG_Apr` , `MG_Point` , `MG_OriginationFee` , `MG_MinPayment` , `MG_MaxAmount` , `MG_Offering` , `MG_Expiration` ) VALUES ('', 'n', '5', '4.895', '0.00', '0.00', '5', '500000', '2003-04-01 00:00:00', '2005-04-01 00:00:00');
Program Specifications Example
2. Update the expiration date of an existing money market product.
SQL Command: UPDATE moneymarket SET MM_Expiration = "2006-04-01" WHERE ProductID = "4"
The Final Product
• Lets go to the site
Testing Documentation
• Pages 32 - 47 of Documentation
• Conducted:1. Black box testing (testing against
requirements)
2. White box testing (testing of coding)
3. User interface testing
4. Use scenario testing
5. Security testing
Problems
• Having the database down for 6 days during the implementation stage
• Learning curve for new technology – none of us knew asp.Net; most hadn’t used MySQL
• Formatting the update text boxes in asp.Net
Where We Could Improve• Allow more time for implementation
stage….or not have the database server go down for 6 days
• Add more documentation to the site so that future programmers could read our code
• Consider using a less constraining design; one that allows for wider tables.
Additional Functions that Could be Added
1. Security. In the current system, even if a user should login with an appropriate username and password in order to get into the bank intranet site, the site is not completely secure. For instance, if a user copies and pastes the url of one of the manager pages, she/he can go to the same page without login. This problem should be prevented with using cookies or session variables.
2. Data validationIn the current system there is data validation for numeric and date fields for all adding pages, but not for the updating pages. Data validation should be added throughout for all the updating pages in case a user makes a mistake during the updating process.
Additional Functions that Could be Added
3. Page Index FunctionIf there is the page index function in the table view page, the search from dropdown menu does not behave appropriately. For instance, when a user views the all product and goes to the second page, a user can not select any other options from dropdown box. With this problem, the page index function was removed from the current system.
4. Sort FunctionFor the column-by sort function, we had to select the exact same table column names as the database. If we named the column name differently for user friendly purpose, the column-by sort does not function appropriately.
What We Learned
• Increased our cooperation & communication skills
• Learned or at least advanced all of our knowledge of asp.Net and MySQL databases
• Increased project management & time management skills
