Course Details

Learn the key concepts of SQL (Structured Query Language) the powerful and standard database management query language for relational databases. SQL (Structured Query Language) is one of the best programming languages for beginning web developers to learn. This course will teach you the basics of designing and writing SQL queries to execute on a practice database. Using a SQL Server Express, you'll learn several real-world applications for SQL so you can put this valuable skill set on your resume.

How It Works

This course is fully online, you require internet access and an email account. The course duration is 6 weeks, followed by a 2-week period to complete the final exam (online, open book). Lessons are released on Wednesdays and Fridays of each week, for a total of 12. You are not required to be online at any specific time. In addition to the specific lesson content, there is a discussion board with each lesson and often there is an optional assignment to apply the learning. Following each lesson, there is a short multiple choice quiz. Your score on these quizzes does not count towards the final mark but completing these helps solidify your learning as well as prepare you for the final exam. The final exam is an open-book, multiple choice exam and you need to achieve a minimum of 65% on the final exam to pass the course. There is only one opportunity to pass the exam. A certificate of completion from WatSPEED is available within four weeks of successful completion of each course and can be accessed in your student portal. Many of the Ed2Go courses are eligible towards the various online certificates offered by WatSPEED.

Syllabus

Lesson 1 - Introduction to Database Design and SQL. In this introductory lesson, you will examine database terms and concepts. Understanding the purpose of a database is foundational to writing efficient SQL queries that retrieve the right data.

Lesson 2 - SQL Server. In this lesson, you will install SQL Server Express and the SQL Server Management Studio to use throughout the course in your learn-by-doing practices. You will use SQL code to create one of the tables for the practice database in SQL Server.

Lesson 3 - Retrieving Data Result-Sets. SQL queries are the statements used to retrieve data from the database. Queries are written in a specific, logical order. In this lesson, you will explore various ways to write SQL queries to retrieve data that meet defined criteria.

Lesson 4 - Sorting Data. SQL queries are defined and written to retrieve data in a certain order. Queries are also written to limit columns and to filter data rows. In this lesson, you will practice writing queries that meet defined criteria and retrieve the expected result-sets.

Lesson 5 - Designing SQL Data Tables. This lesson is about designing SQL data tables for a database. You will explore the relationship concept and how it is used in an RDBMS. You will define tables that are structured according to RDBMS standards. You will also create the tables to add to your practice database.

Lesson 6 - Designing Data Rows. In this lesson, you will add data to your newly defined tables. You will explore several methods of adding data to a table and practice writing and executing these query statements. After adding several individual rows to the tables, you will use a SQL query to populate your tables with enough data rows to use in the learn-by-doing practices in this course.

Lesson 7 - Getting Data From Two Tables. SQL JOIN statements are used to retrieve data from more than one table. In this lesson, you will practice writing JOIN statements that retrieve data from tables that have a relationship between their PKs and FKs.

Lesson 8 - Retrieving Data From Multiple Tables. In this lesson, you will continue writing JOIN statements that retrieve data result-sets from more than one table. You will also examine how and when to use SQL subquery statements to retrieve data from multiple tables. You will practice defining and writing JOIN and subquery queries.

Lesson 9 - Keeping the Database Up to Date. The quality of the data in the database depends on its integrity, including the concepts of data accuracy and consistency. In this lesson, you will explore writing queries to maintain the database so that it is up to date with data that is accurate, consistent, and has integrity.

Lesson 10 - Aggregate Functions. In this lesson, you will examine the concept of aggregate functions and how they are used in query statements to examine multiple rows. Aggregate functions are a method of retrieving summarized data that is useful for analysis.

Lesson 11 - SQL Views. SQL views are an important concept in database design and in using databases. In this lesson, you will explore designing and writing queries to create views. You will also explore the reason they are valuable for database security and database access.

Lesson 12 - Maximize Database Integrity and Performance. Constraints are one way to maximize the integrity of the database and minimize the opportunity for user error. Indexes are used for increasing the performance of a data query. In this lesson, you will explore both these concepts.
