is at the base of the pyramid (data governance framework). The second level is about data architecture, data quality, and metadata management, which lay the foundation for the third level, which is devoted to d
Welcome to the third and final installment of our series “Data Modeling: The Unsung Hero of Data Engineering.” If you’ve journeyed with us fromPart 1, where we dove into the importance and history of data modeling, or joined us inPart 2to explore various approaches and techniques, I’m...

Data modeling starts with understanding the business needs of an organization and then understanding its data — the conceptual modeling stage. From there, the data modeling process defines data elements, the relationships among them and the data structures they form (logical modeling) in order to c...
is “the process of creating a data model.” While that definition isn’t very useful, I hope this blog post will provide a helpful introduction to the concept of data modeling. At Credera, we help our clients become more data-driven, and often that starts with cleaning and modeling data...
Why is data modeling done? Data modeling is a core data management discipline. By providing a visual representation of data sets and their business context, it helps pinpoint information needs for differentbusiness processes. It then specifies the characteristics of the data elements that are include...
An example is used to illustrate the ER modeling principles developed in this chapter. Conceptual data modeling, using either the ER or UML approach, is particularly useful in the early steps of the database life cycle, which involve requirements analysis and logical design. These two steps are...
The collection of data, rules, procedures, and relationships that must be followed are contained in the knowledge base. CHARACTERISTICS OF VALUABLE INFORMATION. In order for information to be valuable it must have the following characteristics, as adapted from Ralph M. Stair's book, Principles of...
A data model is a graphical view of data created for analysis and design purposes. Data modeling includes designing data warehouse databases in detail, it follows principles and patterns established inArchitecture for Data Warehousing and Business Intelligence. ...
The materials-science community has realized long ago that it is necessary to structure data by means of metadata schemas. In this Section, we describe the pioneering and recent examples of such schemas, and how a metadata schema becomes FAIR-data-principles compliant. ...
