Database Design

I’ve been practicing agile database techniques for about twenty years now. My use of these techniques didn’t start as a set plan; rather, it evolved over time as I consulted on various projects. It made sense to look for ways of working faster and with greater customer interaction.I can think of at least three kinds of agile database techniques:Data modelingData warehouse developmentDatabase reverse engineeringAgile Data ModelingMany think of data modeling as a laborious task. But that need not be the case. You can take data modeling out of the back room and do it in front of a customer.

They are thrilled to have IT as a facilitator rather than a roadblock.

Agile Modeling: Not an Option Anymore

The world is changing.No –the world as we knew it in IThaschanged.Big Data & Agile are hot topics.But companies still need tocollect,report, andanalyzetheir data. Usually this requires some form of data warehousing or business intelligence system.

We cannot spend months doing detailed analysis to develop use cases and detailed specification documents. Then spend months building enterprise-scale data models only to deploy them and find out the source systems changed and the models have no place to hold the now-relevant data critical to business success.

Database design is the process of producing a detailedmodelof a database. The start of data modelling is to grasp the business area and functionality being developed.Before Modeling: Talk to the Business PeopleThis is a key principle in information technology. We must remember that we provide a service and mustdeliver 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.

Data Modeling in Agile Development: One Data Modeler’s Experience

Data modeling or database design is the process of producing a detailedmodelof a database. The start of data modeling is to grasp the business area and functionality being developed. When we work with an Agile process (in this case, Scrum), there is a tendency to assume that everyone can work with everything. However, I would like to point out flaws in that idea and my recommendations related to data modeling and Scrum.

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.
