The anticipated language would address all the above issues at the price of confinement to a specific set of rules. Let’s say you have implemented a banking system that allows customers to enter any branch and open a bank account for personal or business use. Everyone is responsible for a particular step in the application’s approval process.
How To Design Scalable High-level Design (HLD) Systems
It provides and explains the logical design of the upcoming (or existing) code and sets the expectations for features and modules the developer needs to create. Technical documentation creation is a critical step for a successful IT project, no matter whether it is big or small. When you have a team of people working on the same product, building it for someone else, communication is vital. Later after you finish the positive flow, we can design the negative flow. Like when the API call is failed, business error, external system down, or cannot be reached. All that can be added here in the High-Level Solution, or we can keep it later for the Detailed Design.
Benefits and Advantages of Creating a High-Level Design
This involves creating visual representations (wireframes) of the screens and layouts that will be present in the final system. Tools like Adobe XD, Sketch, or Figma can be used to create wireframes quickly and efficiently. The output of the HLD process is typically a set of diagrams, such as block diagrams, entity-relationship diagrams, or class diagrams, that describe the system’s architecture at a high level. The HLD is usually reviewed by the stakeholders, including the customer, development team, and management, to ensure that it meets their expectations and that the proposed design is feasible and will meet the requirements. By doing this organization now will have base documentation on how the feature will be. We can present our solution upfront to explain how the feature work and what we need to implement.

Also, list any known vulnerabilities or potentially insecure dependencies. Ifsomehow your application doesn’t have security considerations, explicitly state so and why. Typically this has your API details like request and response parameters at a high level.
That has consistently confused everyone everywhere, and also actually been the source of bugs and serious misunderstandings. Design overview—As the project proceeds, the need is to provide an overview of how the various sub-systems and components of the system combines together in a frame. All systems must log information at various levels for the log analysis system to collect and analyze. Log information allows us to understand system user behavior and system related business metrics.
Creating Wireframes and Mockups for the User Interface
The main thing is to show what the components are that will need to be built or interacted with to support this design. There is nothing so frustrating as a diagram and nothing else, and you are left to try and figure it out for yourself. Here’s an example of one I might have pulled together with a product owner to define a domain for a survey feature. The first section I always have is an overall problem statement, and then a list of requirements. I strive to have these requirements defined as scenarios, use cases, or acceptance criteria.
Brief Overview of the System Requirements and Goals
We'd love to meet online and discuss your project's ideas and requirements. The next step is to add the external system that we needed for each API. If you already know the system name you can put there specifically, either way, you can put the function first like “Payment Gateway” etc. Based on this question we need to come up with the answer by the system diagram. We can draw it like this, in this case, is a mobile application, by connecting it to the require Micro Services and what external system that we need. I am passionate about software, technology, science, and photography.

It also covers the migration of interface/data prior to decommissioning. This section identifies all the opportunities for decommissioning and achieving Organisational benefits in reducing complexity, support costs, licenses, and resources. This section details the implementation and deployment approach, describing the capabilities, release dependencies and ongoing change impacts. This section provides the necessary considerations for the Application Build & Release Teams.
Understanding High-Level Design (HLD) and Low-Level Design (LLD) in Software Development
The LLD defines the specific data structures and algorithms that will be used, as well as the interfaces between the components of the system. It also addresses issues such as error handling and recovery and defines any necessary data validation rules. The goal of LLD is to provide a clear, step-by-step plan for the implementation of the system, including detailed pseudocode or other representations of the algorithms and data structures that will be used. High-level design plays a crucial role in the software development lifecycle (SDLC) by providing a clear and detailed plan for the development team to follow.
Create data flow diagrams and define the information architecture of the system. This will provide a clear understanding of how data is processed and stored within the system. It is the main point of interaction between the user and the system. Therefore, prototyping and wireframing the user interface is an important step in the high-level design process.
Please choose diagrams which best explain your solution as every problem statement, and every solution is different. A log file records details of events occurring in a software application. The details may consist of microservices, transactions, service actions, or anything helpful to debug the flow of an event in the system. This can also be useful for tracking the health and performance of a distributed system, as well as for debugging issues that may arise.
Both these steps help catch and fix issues early, making the overall software development process smoother and more reliable. Software solutions can be very complex and typically involve many stakeholders. List and define the user profiles interacting with the system, such as online users, system admins, or application admins. This section captures the user’s expectations of how they intend to operate the system. These expectations will drive the development of the necessary UI components, reports, and internal software functionality to make that happen.

The value of documentation and design has been downplayed significantly with Agile practices, although the advent of powerful content creation tools like Confluence has started to reverse the tide. This article examines all aspects of a High-Level Design for a project. It will give software practitioners an idea of when, why, and how to create a valuable HLD. Architecting a solution generates different concepts and selects an optimal candidate that satisfies budgetary and planning constraints while mitigating project risk. I use the E/R diagram standards to indicate cardinality (one-to-many, many-to-many), as I find they are easier for non-technical folks to understand than UML. But I pull in the triangle notation from UML to indicate the is-a-kind-of relationship such as the different types of questions above.
Collaboration, clarity, and stakeholder management keep everybody happy. The team’s morale remains high, and the customer remains satisfied and willing to do more business with you. Finding the right balance between quantity and productivity can take time, but it will be worth it. It also requires ingenuity to focus on critical and subtle information only and present it in a way that facilitates quick reading and assimilation. These limitations are more pronounced when systems increase in complexity, with many layers of abstraction requiring multiple decomposition levels.
Also it’s not uncommon for the process of building the domain model to impact the requirements. A well-designed high-level structure should prioritize modularity and scalability. Breaking down the system into logical modules allows for easier development, testing, and maintenance. Additionally, designing with scalability in mind ensures that the system can handle future growth and changes in requirements.
Technical documentation, architecture, and design, especially for large system integration projects, remain integral parts of the delivery of large software projects. As mentioned earlier, prototyping and wireframing the user interface provide valuable insights into the system’s look and feel. Create wireframes and mockups using design tools of your choice to represent each screen’s layout and flow. This will assist in aligning stakeholders’ expectations and gaining valuable feedback.
