Explain the strengths of each and the differences among the 12 types of data models. Create business terms, logical, and physical data models across relational, dimensional, document, and graph approaches. Apply practical techniques such as normalization, dimensional grain and meter design, JSON nested arrays, graph patterns (RDF and Property), denormalization, indexing, views, and partitioning.

Become adept at identifying the characteristics used to distinguish each of the 12 different types of data models. There are three levels of detail (align, refine, and design) and four main modeling mindsets (relational, dimensional, document, and graph), leading to 12 different types of models we can create. Align is where we create the business terms model (conceptual data model) to establish a common business vocabulary. Refine is where we create the logical data model to precisely capture the business requirements. Design is where we create the physical data model to document a technology-optimized version of the business requirements. Relational helps us capture business rules, primarily for operational applications (OLTP) and large integration hubs such as data warehouses. Dimensional helps us capture business questions, primarily for analytical applications (OLAP). Document helps us capture nested structures, used for storing and retrieving highly related content (like documents). Graph helps us capture patterns in the data, used for understanding and predicting connections. We'll cover the 12 types at a high level and provide an example of each.

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.
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
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.
