Security Approaches in Data Modeling. Part 3

This is the third of our multi-part series on applying information security approaches to data modeling. The series uses a simple data model, something to manage social clubs and interest groups, to provide the content we look to secure. Later we will address modeling for authorization and user management, as well as other parts of a secure database implementation. In social situations, it’s common to “read between the lines” – deducing the unspoken assumptions and assertions in a conversation.

“Is It Secret? Is It Safe?” Handling Sensitive Data in Your Data Modeling

Early in the movie “The Fellowship of the Ring”, the wizard Gandalf asks the hero Frodo this question: “Is it secret? Is it safe?” We may not have a magic ring to protect, but we’re asking the same question. But we’re talking about information. This is the second in a multi-part series on how to apply information security principles and techniques as part of data modeling. This series uses a simple data model designed to manage non-commercial clubs as an example of security approaches.

Database Design: More Than Just an ERD

Database design is the process of producing a detailed model of a database. The start of data modelling is to grasp the business area and functionality being developed. Before Modeling: Talk to the Business People This is a key principle in information technology. We must remember that we provide a service and must deliver value to the business. In data modeling that means solving a business problem from the data-side such that the required data is available in a responsive and secure way.

Database Modeling in Scrum Teams

Welcome! This is my first blog entry. I would like to invite you to explore the world of Scrum and databases. I’m a professional Scrum master. During my work, I’ve frequently encountered difficulties when collaborating with others to model a database. I would like to present crucial elements of applying Scrum. I will prove that Scrum is a perfect solution for plenty of teams. A Long Time Ago, in a Galaxy Far Far Away – Waterfall A lot of development teams use waterfall or combine waterfall with iterations.

5 Steps for an Effective Database Model

Database design is the process of producing a detailed model of a database. This model contains the necessary logical (table names, column names) and physical (column datatypes, foreign keys) choices to translate the design into a data definition language (aka SQL), which can be used to create the actual physical database. When I need to create the design for a new database, in other words, the data layer for an application, I follow a few mental steps that I think can help others when they need to go through the same process.

How to Create a Database Model From Scratch

So you want to create your first database model but you don’t know how to start? Read on! I assume you already know a little about tables, columns, and relationships. If you don’t, watch our video tutorials before you continue. Start With a System Description You should always start creating a database model with a description of a system. In a classroom situation, a system description is given to you by a teacher.
