UML Class Messaging System
M
MermaidMap the structure of a messaging system from the ground up. This template lays out core entities — conversations, messages, users/contacts, channels, attachments, and notifications — plus how they relate. It’s a solid starting point for API design, data modeling, and implementation planning.
How to create a UML Class Messaging System
To create a UML class messaging system, follow these steps:
01.
Identify Your Classes
Define the main objects in your system that encapsulate data and behavior (e.g., MessagingSystem, User, Message, Conversation).
02.
List attributes
For each class, specify the properties it holds, including data types (String, UUID, List, DateTime, etc.).
03.
Define methods
Identify the functions each class can perform, including parameters and return types (e.g., sendMessage(), addContact()).
04.
Create class boxes
Draw rectangles divided into three sections — class name at top, attributes in middle, methods at bottom.
05.
Map relationships
Determine how classes connect — does MessagingSystem manage ConversationThreads? Does Message have Attachments?
06.
Add relationship lines
Draw lines between classes with appropriate notation (arrows for dependencies, diamonds for composition, numbers for cardinality).
07.
Specify cardinality
Show whether relationships are one-to-one, one-to-many, or many-to-many using notation like 1..*, 0..1.
08.
Review & share
Share the diagram for development planning, code reviews, API documentation, or architectural decision records.

Map how work actually moves through your team. This template shows how ideas are scored, communicated, researched, prioritized, and either promoted to the roadmap or parked — with explicit decision points and feedback loops. It helps teams stay aligned on next steps, understand why decisions were made, and onboard new members without endless meetings.

State-Machine Based Decimation Filter for LiDAR UART Streaming
A state machine for reading a continuous stream of 5-byte UART messages from a LiDAR scanner into an embedded system — in real time, with configurable decimation. Rather than capturing everything and filtering later, this design processes bytes as they arrive and skips every Mth message on the fly. Five states handle the full lifecycle: idle, pattern detection, offset alignment, recording, and skipping. Built for embedded systems engineers, robotics researchers, and anyone working with sensor data pipelines where memory is constrained and throughput matters.
