architecture diagram as code

December 12, 2020   |   

These days we use everything as code approach for documentation, infrastructure provisioning, deployment automation, continuous integration build jobs, pull request and issue templates, and many other things. Leverage native APIs on every platform while maximizing code-sharing across all of them. Tools like PlantUML, Mermaid, and WebSequenceDiagrams have auto-layout algorithms that allow us to focus on content too. NDepend has been one of the first tool that uses treemap to visualize code. Structure101 architecture diagrams use a concise visual notation for representing architectural layering and composition. Edges are also colored accordingly and dashed edges are used to indicate indirect dependency. The most common form of n-tier is the 3-tier Application, and it is classified into three categories. Also, I am still learning Diagrams library so the code shown below might not be the best. This code, which was used to create the software architecture model, can be thought of as an executable domain specific language, or an executable architecture description language. Since this talk is about AWS we will be building diagrams that use AWS services. Visualizing the internal structure of components and how they interact each other is the natural way of using a dependency graph to visualize architecture. ... Android, and Windows using .NET. This will mean quite a lot of refactoring for us, like for example to adapt our UI to propose a web or a multi-platform experience. Over the years, I gained a passion for understanding structure and evolution of large complex real-world applications, and for talking with talented developers behind it. Double clicking an edge between two components shows which classes and methods from both components are involved into the coupling. Diagrams currently supports six major providers: AWS, Azure, GCP, … Then maybe you need an Architecture Development Environment (ADE). on Pinterest. This is the first image Google returned for “architecture diagram” - consistent with what I saw in IT for 20 years. Don’t you think that’s over engineering a very simple idea of putting texts in a box. Layering and composition. With Diagrams, you create diagrams by writing Python code. The code run can be scheduled using unix-cron job. Now, we will use running application instances in multiple AZs. But to me draw.io is still not the pure as code tool. In the commands shown above, we first installed Graphviz. 2. Modern IDEs like Visual Studio offer plenty of ways to browse code (detailed in this post 10 Visual Studio Navigation Productivity Tips). It was born for prototyping a new system architecture without any design tools. ... or ‘EC2’ instance on AWS). The fact of the matter is that we all have to create diagrams in our software engineering life. The graph improvements are: The graph below shows the architecture of the code of the dependency graph itself. Next, we installed diagrams library. Shekhar Gulati is a software developer and hands-on architect. who have direct involvement in the project. If the diagram needs to be modified in the future, we just need to modify the description and the nodes … However for a long time we favored the Dependency Structure Matrix (DSM) shown in the next section. When you draw in a drawing program, you have to “paint” everything by hand most of the time. I graduated in Mathematics and Software engineering. Listing 2 – Diagrams Code that Generates Architecture Diagram In order to group components, I use with Cluster and give it a name. You use it like just any other diagram tool. Software architecture relates to dependencies between the various elements of a code base: components, packages, namespaces, classes, methods, fields… All Object-Oriented Programming (OOP) concepts are somehow related to dependencies: When it comes to dependencies visualization in a code base the usual boxes and arrows dependency graph is the royal kind of diagram to use. Clearly on such super-entangled structure the DSM view is more readable. A popular components is identified through the highlighted row. More generally focusing on code smells introduced since the last release is a powerful way to get used to write better code. For a single user application, we can use following: The Python code for the diagram is shown below. Post was not sent - check your email addresses! In this book R.Martin exposes the Dependency Inversion Principle (DIP), one of the famous SOLID principles. Domain object table. Here’s what works for me. Now you have cut your teeth on building a beautiful diagram with code there’s a lot of potential with leveraging this workflow when it comes to automation possibilities, and time saved with general maintenance of an architecture diagram. Any sufficiently large enough system cannot be mastered without some sort of visualization. Details should depend on abstractions. Visualize code: - See the code's organization and relationships by creating code maps. A well-designed system architecture diagram template created with Edraw architecture diagram softwareis provided below. new and revolutionary platform created by Microsoft for developing applications 1 It still does not give all the freedom and you will be constrained by it. Notify me of follow-up comments by email. I… If someone asked about the features of an ideal project, responses would surely mention a few specific things. Here is an example of one of the architecture diagrams that we use for the structure101 code-base. Most tools stand on the shoulders of other powerful tools. In the first screenshot above we saw that layered code, high level and low level components, can be easily identified. This is quite useful information. The same way the DSM relies on an heuristic to naturally group rows and columns to highlight dependency cycles. Your email address will not be published. His skills include Java, Serverless and Microservices architecture, Containers, and Kubernetes. This principle states: a. Plenty of features are proposed to quickly obtain the right perspective the developer needs to study some code. See more ideas about diagram architecture, concept architecture, architecture presentation. Generate a Code Map for the solution using the Architecture menu. It signifies command prompt. Now that we have met our prerequisites. Enter your email address to follow this blog and receive notifications of new posts by email. Fundamentals of Data Architecture to Help Data Scientists Understand Architectural Diagrams Better. ), advanced post-process (like routers for arrows or zoom-in/out detailed mip-mapping) and of course you can easily commit changes to github. Treemaping is a way to visualize metrics and hierarchical data. Documents to be generated. I will keep following this library and hopefully contribute back. It is an open source graph visualisation software that makes use of abstract graphs and network to represent structural information. In my experience, outside of the team, there are very few stakeholders who r… My dad being an early programmer in the 70's, I have been fortunate to switch from playing with Lego, to program my own micro-games, when I was still a kid. Here see this graph exported to SVG vector format, expanded till the method level. For example below in the NopCommerce code base we search all namespaces related to the entity customer. Both should depend on abstractions. The key is to really add value over existing software visualization technologies. Why would you want to have a code first approach for creating architectural diagrams. Since then I never stop programming. With a single click the user can generate a graph made of direct and indirect callers and callees of an element. Please note that I will be deviating a bit from the architecture presented in the video. Gliffy. Designing clean architecture is related to the static view of code. Required fields are marked *. Small rectangles are methods of the NDepend code base. There are many tools to visualize software architecture through dependency graphs but our implementation scales live on large code bases with thousands of elements. Also CQLinq makes possible many other use-cases than just code visualization including: code rules, smart technical-debt estimation, quality gates, reporting, trend charts, code search, audit legacy code, prioritize hot-spots to fix first, API breaking changes detection… This led the community to re-name the tool as the swiss-army-knife for the .NET developers. Ever looked at the source and really wondered? The graph on the right is quite unreadable and doesn’t provide such information. This is the, code hierarchy (projects contain namespaces that contain classes that contain members), usage of OOP concepts (inheritance, virtual methods, encapsulation…), state mutability (assigning a field, immutable class, pure method…), delta between the actual snapshot and a baseline snapshot. Diagram as Code also allows you to track the architecture diagram changes on any version control system. This architecture model provides Software Developers to create Reusable application/systems with maximum flexibility. The following code snippet provides a sample implementation of Resource: Resource I will use examples mentioned in the talk: Scaling Up to Your First 10 Million Users. This led first to CQL Code Query Language, that had been quickly refactored to CQLinq Code Query over C# LINQ shortly after the LINQ revolution era early in the 2010’s. CQLinq quickly became the backbone of the tool and all architecture diagrams explained above are based on it. Required fields are marked *. To get started with Diagrams, you need to run following commands. As software engineers and architects we all have to create architecture diagrams to convey our ideas with other fellow engineers.
