Introduction to Database Systems

Different databases serve different purposes; each one is dependent upon both deployment environment and different types of user interactions.  In this Topic, we will ask a number of questions pertaining to databases: What are some database environments and user types?  How can the database management system ensure control over data integrity, avoid data redundancy, and secure data, while at the same allowing interactions with different user types?  In answering these questions, we will identify and determine the characteristics of databases, their many deployment environments, and the different categories of users that interact with it.

Database Architecture and Date Languages

In order to properly create and then manage a database, we need to have a thorough understanding of the data it holds.  Because data can be seen from different levels, we will introduce different data models and learn how to apply them in order to describe the structure of the database, thereby providing a “view” of the database for the different types of users introduced in the previous section.

Database History

Databases have existed for centuries: the maintenance of records and data has evolved from engravings to cards to digital storage.  In this Topic, we will present the four different models of representing data, discussing the different limits of each.

The Entity Relationship Model

Databases often hold a great amount of data.  In order to build a database, we need to understand which entities should hold data and identify the connections that may exist between entities.  In this Topic, we will learn about the Entity-Relationship model, which will allow us to create a graphical view of the different elements of a database as well as the relationships between them.  We will also learn the drawing conventions of the E-R model using a part-to-whole approach, beginning with those conventions used to represent a single entity, and concluding with conventions used to represent all relations in a database.

The Relational Database Model

The relational database model provides us with a way to understand how data can be perceived.  While the E-R model represents the relations between elements of a database, it does not provide a conceptual view of its data.  We will use the relational model to solve that problem.  The relational model looks at entities as tables and allows operations to be performed on them.  In this Topic, we will learn how to map ER models into relations.

Relational Algebra

We have seen that database entities can be viewed as logical tables. While this is useful in its own way, we can learn more from the data if we can perform operations on the tables within a database, as data from one table may not be meaningful without the data from another table.  In this Topic, we will introduce relation algebra, the mathematical notation used to represent how data retrievals and updates are performed on tables in a database.  Understanding relational algebra will serve as a prelude to using the Structure Query Language (SQL).

Intro to Data Normalization

In this course, we have learned that entities in a database can be thought of as logical tables.  We will now learn that data in a table must be stored in a normalized way.  We will first identify the properties of a normalized table, learning about the process of normalization and its importance to the structure of a database.  We will then study the four major steps of normalization and discuss the database anomalies that can result in the absence of normalization.

The Join Statement

Programmers frequently join data from a number of different tables in order to obtain more information.  They also—perhaps even more frequently—build queries to obtain information from more than one table in order to generate better information.  In this section, we will learn about SQL Joins, which allow us to create complex queries, combine data from different tables, and obtain a new result set that can provide us with a better understanding of the data and maximize database flexibility.
