The purpose of Sequence diagrams is to specify dynamic system behaviors as message-passing collaborations among prototypical Blocks (Parts). Understanding databases is essential in system design because they are the foundation for managing and storing data efficiently. Having in-depth knowledge of database concepts allows designers to make informed decisions about how data will be stored, queried, and managed within the system. It ensures that the system can handle large volumes of data effectively, while also ensuring data integrity and security. This article is an important resource if you’re new to system design and aiming for interviews at top tech companies.
What is architectural diagramming?
A few of these processes include fault tolerance, partitioning data, and aggregating data. The abstractions allow the user to focus on the higher-level logic of their programs while trusting the framework to smoothly continue underlying processes. PostgreSQL, also known as Postgres, is an open-source RDBMS that emphasizes extensibility and SQL compliance.

If you wanted to go a level deeper, you could create a container diagram. A container diagram would focus on the applications that make up a specific container. At other times, under-documenting vital parts of software architecture in a complex system can lead to significant issues or contribute to technical debt.

Their simplicity makes them an effective tool for visualizing the logic of an algorithm or program before you start coding. Tutorials Point is a leading Ed Tech company striving to provide the best learning material on technical and non-technical subjects. Documentation is a process of recording the information for any reference or operational purpose. It is important that prepared document must be updated on regular basis to trace the progress of the system easily.
Over the last two decades, there have been a lot of advancements in large-scale web applications. These advancements have redefined the way we think about software development. All of the apps and services that we use daily, like Facebook, Instagram, and Twitter, are scalable systems.

It breaks down system design concepts into easy-to-understand steps, starting from the basics and gradually advancing to more complex topics. By the end, you’ll be equipped with the knowledge and confidence to tackle any system design questions in interviews and excel in your new role. If a server goes down while the application is processing a user request, the load balancer automatically routes future requests to servers that are functioning.
Architectural Styles
The document fields can vary, making it easy to change the structure over time. A redundant array of inexpensive disks, or RAID, is a technique to use multiple disks in concert to build a faster, bigger, and more reliable disk system. Internally, it’s a complex tool, consisting of multiple disks, memory, and one or more processors to manage the system. A hardware RAID is similar to a computer system but is specialized for the task of managing a group of disks. There are different levels of RAID, all of which offer different functionalities. When designing a complex system, you may want to implement RAID storage techniques.
This cheat sheet is a stepping stone towards achieving that mastery, providing you with a foundation and a quick way to refresh your memory. As you delve deeper into each topic, you'll discover the intricacies and fascinating challenges of system design. It is advised that you should dedicate 1–3 months to consistent study and practice. Aim at understanding various system architectures and engaging with increasingly intricate design challenges.
Sequence diagrams in UML show how objects interact with each other and the order those interactions occur. It’s important to note that they show the interactions for a particular scenario. The processes are represented vertically and interactions are shown as arrows.
Good software architecture diagrams are sources of truth and clarity. You want your diagram to quickly convey a software system’s essential composition and behaviors to both technical and non-technical audiences. A complex system of databases, servers, and APIs could take hours to explain. But a clean, well-thought-out diagram makes the relationships easy to understand and remember.
The good news is you don’t have to be an artist to draw architecture diagrams. An intelligent diagramming app like Lucidchart makes it easy to create architecture diagrams and share with your team or stakeholders. You would use this type of diagram to look for ways to improve the application deployment process. You will need to update and improve your DevOps architecture to keep up with continual improvements of deployment tools and changes to other interfacing systems architecture.
This kind of example would likely be created at the beginning of the project to determine the scope, goals, and what each person is responsible for. Due to the hierarchical nature of the C4 model, each diagram will change at a different rate. Hover your mouse over the diagram, find elements with a , and double-click to zoom-in. Large applications, such as Instagram, Facebook, and Uber, are n-tier applications. To shard your data, you need to determine a sharding key to partition your data.
This concept is important within distributed systems and works closely with data partitioning and data replication. Block storage is a data storage technique where data is broken down into blocks of equal sizes, and each individual block is given a unique identifier for easy accessibility. As opposed to adhering to a fixed path, blocks can be stored anywhere in the system, making more efficient use of the resources.
