When will I have access to the lectures and assignments?

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

What will I get if I purchase the Certificate?

When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

Is financial aid available?

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.

For many new or intermediate database developers, it’s difficult to know where to start when designing a relational database. It’s easy to make the mistake of assuming that the functionality of a database will take shape over time, or the design will fall into place as you build the database.

This course introduces a process for effectively planning and designing a functional, efficient database. Knowing how to plan a relational database is important to the success of the databases you create. Without planning, you cannot possibly know what the database needs to do, or even what information to include in the database. Planning a database is essential and prevents the extra work of fixing data maintenance problems later on. The concepts are not specific to a particular software application and can be applied to any relational database management system. This course is designed for students who need to learn database design essentials, typically in preparation for, or as a supplement to, a course on SQL such as Logical Operations' SQL Querying: Fundamentals and courses on specific relational database platforms. In this course, you will: follow an efficient process for designing a relational database; define the database conceptual model; define the database logical model; apply database normalization methods to improve the initial design of a database; and complete the database design, including controls to ensure its referential integrity and data integrity.

单元详情

You have data that needs to be stored in a database. You may have used a database program before, but using a database and creating one are not the same thing. In this lesson, you will gather information to plan a database.

You've incorporated into your database design all of the concepts that you need to represent. You've identified tables and many of the columns that need to go into them, as well as the relationships between each table. Now it's time to perform some quality control on your design.
