The special bonus is when you’ll use the pen tool to see how to easily add a shape and color to your business card to make it stand out from others. Photoshop is a good tool to use to make business cards for all levels of users, it’s easy enough to learn for a beginner and it has advanced features for more advanced users.

In this course you will learn to write advanced SQL (Structured Query Language) retrieval queries using SQLiteStudio. Retrieving data from a relational database is one of the primary methods used by application and web developers to display data and populate web pages. Since a database can be made up of a complex combination of relational tables, retrieving that data can be challenging. You can meet those challenges by gaining experience with some of the more advanced SQL coding techniques. Through hands-on practice you will write SQL code to use functions and grouping, sub queries, calculated fields, and conditional expressions. In addition, you will experiment with alternative methods of joining tables for data retrieval. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.

Have you ever wanted to build a database but don't know where to start? This course will provide you a step-by-step guidance. We are going to start from a raw idea to an implementable relational database. Getting on the path, practicing the real-life mini cases, you will be confident and comfortable with Relational Database Design. Let's get started! Relational Database Design can be taken for academic credit as part of CU Boulder’s Master of Science in Data Science (MS-DS) degree offered on the Coursera platform. The MS-DS is an interdisciplinary degree that brings together faculty from CU Boulder’s departments of Applied Mathematics, Computer Science, Information Science, and others. With performance-based admissions and no application process, the MS-DS is ideal for individuals with a broad range of undergraduate education and/or professional experience in computer science, information science, mathematics, and statistics.
