So when, why, and how to start Data Modeling in your project? First off, I am in many projects where non-technical people do not understand their data or even how to document it. There is no reason to "be afraid" of this subject as anyone can do this. Data Modeling in UML does NOT require you are technical, a data architect or developer, or even follow the conventions of data development, management, or documentation. This only requires a basic understanding of your "Modeling Tool" which could be PowerPoint, Visio, Lucidchart, Draw.io or the myriad of offers out there today. The Tools Out of the dozens of "drawing tools" I have used over the decades, I prefer Sparx Enterprise Architect (EA). Sparx EA allows me to draw anything using UML and CASE techniques. In addition, I can put as much intelligence and information under my drawing elements as I want or need, and to continue to update and manage this intelligence. Plus, this intelligence is in a SQL datab...

 I am working with a group of very smart system, application, and business architects. Each group is using different tooling that they are comfortable with.  The Business Architects are using Draw.io,  while the Application Architects are using Visio and Draw.io, and the System Engineers/Architects are now using Sparx EA Most of this Business's Methods and Procedures (M&P) have been using Draw.io to model their M&P, Policies, Rules, and Knowledge Management (KMS) Flows in Draw.io. Then they pass to engineers, architects, and developers for implementations. Their documentation and KMS is very well done. However, there is some confusion and breaks in their knowledge transfer and management, which makes delivery more complicated and slow than it should be. Since ChatGPT did a better job than I in describing Domain Driven Design (DDD), I will use that intelligence below ... Domain-Driven Design (DDD) is an approach to software development that focuses on understanding...

 A good friend and previous co-worker whom I admire and trust, posted on LinkedIn an article, ..." Here's why layoffs keep happening and why ambitious managers are fueling them ". Since LinkedIn doesn't give me enough space to comment, I am here 😀 Good read...however, I have concerns in what I viewed. First off, the author is a "former head of analytics". Why "former"? And should there be more focus on "Advanced Analytics" and not just "Analytics"? Sorry, I don't mean to be disrespectful, but I did not read or see the core reasons why companies fall into this pit. For more on Advanced Analytics vs Analytics, read my post on The Premise of Analytics . Analytics vs Advanced Analytics What is the difference between analytics and advanced analytics? There is a difference between the two, where advanced analytics uses machine learning, data mining, predictive modeling, optimization algorithms, natural language processing, and mo...

The premise of analytics is to leverage data and statistical methods to gain insights and make informed decisions. Analytics involves the systematic analysis of data to uncover patterns, trends, relationships, and other valuable information that can guide decision-making, problem-solving, and optimization. The Premise The premise of analytics can be summarized in the following key points: Data-driven approach : Analytics relies on data as its foundation. It recognizes that organizations generate and collect vast amounts of data from various sources, such as customer transactions, operations, social media, sensors, and more. By analyzing this data, businesses can gain valuable insights to drive strategic decisions and improve performance. Extracting insights : Analytics aims to extract meaningful insights from data. It involves applying statistical techniques, data mining, machine learning, and other analytical methods to identify patterns, trends, correlations, and anomalies within the...

I am starting a series on Modeling Relevance, Telling Stories through Visualization, and basic UML connection practices. This is Part 1 where Part 2 touches on the remainder of association types. The series will dive deeper into building model relevance and using that intelligence to drive other things. More to come...

CASE (Computer-Aided Software Engineering) and UML (Unified Modeling Language) are related but distinct concepts in the field of software engineering. Here's an overview of the differences between CASE and UML: CASE (Computer-Aided Software Engineering): CASE (Computer Aided System/Software Engineering) refers to the use of computer-based tools and methodologies to support various software engineering activities, such as analysis, design, implementation, testing, and maintenance. CASE tools provide software developers with automated support to facilitate the software development process, increase productivity, and improve the quality of the resulting software. CASE tools typically offer a range of features, including graphical modeling capabilities, code generation, documentation generation, project management, version control, and collaboration support. They help in creating, editing, and managing various artifacts and models used during software development, such as requirements ...

I get asked the question, "Is UML a language?"...  The answer is "YES!", UML provides a standardized visual modeling language, but is not a programming language. UML can be used to conduct round-trip software and system engineering. UML (Unified Modeling Language) is considered a language. It is a standardized visual modeling language used for designing, documenting, and communicating software systems and other complex systems. UML provides a set of graphical notations and semantics that allow software engineers, system analysts, and other stakeholders to describe, visualize, and specify the structure, behavior, and interactions of a system. UML encompasses a wide range of diagrams, including class diagrams, use case diagrams, sequence diagrams, activity diagrams, and many others. Each diagram type serves a specific purpose and captures different aspects of a system, such as its structure, functionality, and interactions. UML is not a programming language , as it d...
