What is a Database?

CSE
4701


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.
OV-1.11
What Does a Database Contain?

CSE
4701
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
OV-1.12
Excel Spreadsheet Example

What Does a Database Contain?

CSE
4701
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
private
Date
private
double
private
integer
public
Name, SSN, Address;
BirthDate;
Salary;
DeptNum;
Empolyee() { ... };
};
OV-1.14
What are Problems with each?

CSE
4701
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
