FAMU CMRPDatabase By: Jabare Mitchell Tyshun JonesGassie Orr
Purpose of the Database • The purpose of the database is to allow the developers and users to pull out particular sets of information through queries within our application…. To retrieve data. • (Essentially this version is a draft version due to the fact secure shell is not the software we will be using to implement our app.)
The Makeup of Our Database • Modeled after our ER diagram • Database contains 16 different tables each with its own set of attributes depending on what they are.
Sixteen Tables • Stud • admin • E_coordinator • Safety official • Parking services • Classes • Class section • Class roll • Location • Events • Alerts • Lot • Building • Room • Users • Instructor The Table highlighted in red will be the ones discussed in detail
Admin • ADMIN_ID • ADMIN_USERNAME • ADMIN_NAME • ADMIN_PASSWORD • NOT NULL CHAR(2) • VARCHAR2(25) • VARCHAR2(50) • VARCHAR2(20) The not null highlighted above shows that Admin_ID is the primary key for this table.
Classes • CLASS_ID CHAR(6) • CLASS_NAME • CLASS_PREREQ • CLASS_CREDITS • NOT NULL CHAR(6) • VARCHAR2(35) • CHAR(7) • NUMBER(1)
Alerts • ALERT_ID • ALERT_DESCR • ALERT_TIME • ALERT_DATE • ALERT_TYPE • ALERT_USERNAME • NOT NULL CHAR(5) • VARCHAR2(150) • DATE • DATE • VARCHAR2(25) • VARCHAR2(25)
Location • LOC_ID • LOC_NAME • COORD_LAT • COORD_LONG • NOT NULL CHAR(5) • VARCHAR2(40) • NUMBER(8,6) • NUMBER(8,6)
Building • BUILD_ID • BUILD_ROOMS • LOC_ID • NOT NULL CHAR(4) • NUMBER(3) • CHAR(5) The Loc_ID attribute is a foreign key coming from the Location table. The Build_ID is still the Primary key
The Purpose of the Sample Queries • The sample queries will give us an Idea on how to find information and also how to design our GUI so that we can ask the same questions in an efficient manner. • Lets us know our database is accurate. We will use the same tables for example purposes .
Admin Queries • Figure out all of the Admin’s Names • Count how many admin’s there are • Search for an admin by there username
Classes Queries • Find a class by its name • Find a class by its ID • Find a classes pre-reqs
Location Queries • Get the coordinates to a building • Find a location by its Loc_ID • Count how many locations there are
Alerts Queries • View alert descriptions • View the time an alert occurred by using its Alert_ID
Building Queries • Find a building using from its name or loc_id
