Introducing the Semester Project

12. What is a Database?
Database (DB) is a Structured Collection of Data about the Entities that Exist in an Enterprise and that are Used (Shared) by Applications of an Enterprise
The Structure of the Database is Dependent Upon the Data Model that is Used - Understanding the Terms:
Database (DB)
Database System (DBS)
Database Management Systems (DBMS)
What can be a Database?
Address Book, Contact List, Calendar, Bookmarks, Flat File Against Which a Program is Executed, Real-Time Data Sensor Feed into Embedded Program, Set of Word or Excel Documents, Fitness Data from App or Device, Recipes, etc.

13. What Does a Database Contain?
Conceptually – One View
Consider Excel Spreadsheet with Multiple Tabs
Tabs: Employee, Department, Projects,
Each Tab has Columns that Each have Own Types
Each Tab has Data for All Columns/Multiple Rows
Data is Static, Human Readable/Updateable

14. Excel Spreadsheet Example

15. What Does a Database Contain?
Conceptually – Another View
Consider a set of Java Classes
Employee, Manager ISA Employee, Department, Projects, etc.
Each Class has Single Instance
Need to Use Collection in Java for Set of Instances
class Employee {
private String Name, SSN, Address;
private Date BirthDate;
private double Salary;
private integer DeptNum;
public Empolyee() { ... }; };

16. What are Problems with each?
Both Cases:
Data is Not Stored in a Permanent Repository
Data Not easily Sharable/Modified by Multiple Users Simultaneously
Data Consistency Constraints Not Enforceable
DeptNum in Employee/Project vs. Number in Department
Same Issue across Classes
Need
Way to Persistently store Data
Accessible by Multiple Users

17. Defining a Database Table
CREATE TABLE EMPLOYEE
( FNAME VARCHAR(15) NOT NULL ,
MINIT CHAR ,
LNAME VARCHAR(15) NOT NULL ,
SSN CHAR(9) NOT NULL ,
BDATE DATE
ADDRESS VARCHAR(30) ,
SEX CHAR ,
SALARY DECIMAL(10,2) ,
SUPERSSN CHAR(9) ,
DNO INT NOT NULL ,
PRIMARY KEY (SSN) ,
FOREIGN KEY (SUPERSSN) REFERENCES EMPLOYEE(SSN) ,
FOREIGN KEY (DNO)
REFERENCES DEPARTMENT(DNUMBER) ) ;

18. A Schema Contains Multiple Tables

19. …filled with Rows of Tuples/Instances
Which Represent Tuples/Instances of Each Relation A S C
null W B 1 4 5

20. …filled with Rows of Tuples/Instances

21. SQL Searches the Tables
Retrieve the Birthdate and Address of the Employee whose Name is 'John B. Smith'. SELECT BDATE, ADDRESS FROM EMPLOYEE WHERE FNAME='John' AND MINIT='B’ AND LNAME='Smith’
Which Row(s) are Selected? B S C
null W

22. Main Software for Class
MySQL and MySQL Workbench

23. Loading a Database Schema
Select File, Open SQL Script, and browse to the directory to select demo sql and from the window below, select, the Open option

24. Loading a Database Schema

25. The Database Tables

26. To Load a Database – back to this Tab Click on Localhost
MySQL and MySQL Workbench

27. Takes five or more Minutes

39. Other Technologies - XAMPP
XAMPP includes: Apache, PHP, MySQL, and other goodies. No need to download and install them separately, XAMPP does it all.
Download:
FAQs (Includes instructions on how to install it and set it up):
Windows FAQs:
OSX FAQs:
Linux FAQs:

40. The XAMPP Control Panel

41. Other Use Technologies -phpMyAdmin

44. What to Watch Out for… Suppose Install MySQL + Workbench
Then Install XAMPP Which Also Installs MySQL
May End up with Multiple Instances of MySQL
On Windows/Control Panel/Admin Tools/Services

45. Useful on Windows Control Panel-Admin Tools - Services Stop Start
Pause
Service

47. Chinook Loaded with Query on Employee Arrow shows save to a csv file

48. Query Results in Excel

49. Project Focus
Design, Extend, Develop, and Test a UI/ Information System for Customers and Employees of Either:
NorthwindExtended Database Sample – Database of Employees, Customers, Suppliers, etc.
Phases I and II posted … may be updated before assigned

50. Northwind

51. Clients and Software Architecture
Web Client
Connect and Interact with MySQL
REST php
API
MySQL
Web Client
Front half contains
API (Java calls) that
hide DB interactions
from Client
Back half is the implementation of
the classes that contains code to open
the database connection, perform a
query, collect results, etc.

52. Project Requirements
Team Project - Discussion Between Teams Allowed if you are Helping with DB Configuration, Programming Question, etc., NOT Joint Design/Development!
Will either Be Teams of 3
Implementation Languages/Platform
DB/Server side: MySQL Workbench, php UI
Aptana Studio 3
Mobile UI App Framework
Should work on Chrome
