Course Materials


The accountant of tomorrow will be significantly different from the accountant of the past. The accountant's role has been expanding within organizations and they are becoming part of the management and decision-making team, rather than just providers of financial information. For instance, accounting and finance professionals are mining data, turning information into knowledge, involving IT with development process and communicating what they learn to all levels of the organization.

Major catalysts for this dramatic change are found in recent advancements in computer technology and the advent of e-business. With the latest incarnations of SQL Server 2014, modeling databases and data-mining applications with Microsoft technologies has become easier and much more efficient than ever before.

Outstanding opportunities exist in consulting and in the corporate environment for individuals with both an accounting and information techniques background.

Why study Database Management Systems & Applications?


In a nutshell…Since we are in a technology-driven society, we must understand some fundamental computer-based knowledge and need to learn today to work with the robots of tomorrow!


Understand your data model’s physical elements Master all the elements of a successful logical data model Learn an effective, start-to-finish methodology for creating

logical models Overcome modeling problems related to entities, attribute,

data types, storage overhead, performance, and relationships

Create physical models with SQL Server 2014: from establishing naming guidelines through implementing business rules and constraints

Use SQL Server’s unique indexing capabilities, and overcome their limitations

Create abstraction layers that enhance security, extensibility, and flexibility

Course Goals

Major Topics Familiarizing with relational databases and basic

SQL Relational database theory and normalization

techniques How to create databases and tables Using indexes and constraints How to use SQL to retrieve data, modify data, and

join tables Using system functions and user-defined functions Taking advantage of stored procedures, views and

triggers to design and build applications


Class participation (10%) Individual assignments (20%)

3~5 homework assignments

Certification exam (20%) Midterm exam (25%) Final exam (25%)

Grading Policy


Attend lecture and take notes. Start early on all assignments. Don’t procrastinate. Solving problem in an individual creative process

much like composition. You must reach your own understanding of the problem and discover a path to its solution. Only turn in your own work. Do not collaborate closely with another student while doing the homework unless instructed to do so.

Think and practice in class. Review indicated readings after each class. Do not play with smart phones or any mobile

devices in class.

Okay, so let’s get started… with a crash course in

Databases!

The Characteristics of Databases The purpose of a database is to help people

track things of interest to them Data is stored in tables, which have rows

and columns like a spreadsheet. A database may have multiple tables, where each table stores data about a different thing

Each row in a table stores data about an occurrence or instance of the thing of interest

A database stores data and relationshipsSlides developed by Chien-Hua Tsai 27 Slides developed by Chien-Hua Tsai 28

The Key Characteristic of Databases: Related Tables Naming Conventions in this Textbook

Table Names are written with all capital letters: STUDENT, CLASS, GRADE

Column names are written with an initial capital letter, and compound names are written with a capital letter on each word: Term, Section, ClassNumber, StudentName


Data = Recorded facts and figures Information = Knowledge derived from data Databases record data, but they do so in

such a way that we can produce information from the data The data on STUDENTs, CLASSes and GRADEs

could produce information about each student’s GPA


Databases Create Information

Components of a Database System


Components of a Database System with SQL

Applications are the computer programs that users work with.

The Database Management System (DBMS) creates, processes, and administers databases.

Structured Query Language (SQL) is an internationally recognized standard database language that is used by all commercial DBMSs.


Applications, the DBMS, and SQL

Database Applications—Reports


Relational Databases and SQL

Structured Query Language (SQL) Declarative language for query and

manipulation of relational data. SQL consists of:

Data Manipulation Language (DML) SELECT, INSERT, UPDATE, DELETE

Data Definition Language (DDL)CREATE, DROP, ALTER

Data Control Language (DCL)GRANT, REVOKE

SELECT Name FROM Departments

Sales

Marketing

…


SQL — Few ExamplesSELECT FirstName, LastName, JobTitle FROM Employees

INSERT INTO Projects(Name, StartDate)VALUES('Introduction to SQL Course', '1/1/2019')

SELECT * FROM Projects WHERE StartDate = '1/1/2019'

UPDATE ProjectsSET EndDate = ‘6/30/2019'WHERE StartDate = '1/1/2019'

DELETE FROM ProjectsWHERE StartDate = '1/1/2019'


The DBMS A database is a self-describing collection of

integrated tables The tables are called integrated because

they store data about the relationships between the rows of data

A database is called self-describing because it stores a description of itself

The self-describing data are called metadata, which is data about data
