Top 10 Online Communities for Database Designers
Exploring online communities for database designers: navigating through the best forums and networks for professional growth and learning
In the dynamic landscape of database design, the continuous evolution of knowledge and best practices is a journey, not a destination. For the database designer, this journey is punctuated by the rich interactions and exchanges found within various online communities. These digital forums, ranging from expansive generalist networks to specialized niches, are more than just repositories of information; they are vibrant ecosystems where ideas flourish and professional growth is nurtured.
Top 12 Database Design Principles in 2023
A well-designed data model must support database integrity, performance, scalability, and security. To achieve these qualities, pay attention to the top 12 database design principles explained in this guide.
Database design principles are essential to creating efficient, reliable, and scalable databases. A database created following these fundamental design principles ensures that its data will be stored in it in an organized and structured manner. It will facilitate database administration and allow users to obtain accurate results.
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.
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.
