ER Diagram Maker Live

ER Diagram Maker is a dedicated application for software engineers, database administrators, and students who need to plan and visualize database architecture. The tool provides a blank grid workspace where users can add tables, define attributes, and draw connections between different data entities. By using this ER Diagram Maker, you can construct complex entity-relationship models directly on your Android phone or tablet. The application includes a library of standard ERD shapes, focusing on Crow's foot notation, which is required for accurately representing one-to-one, one-to-many, and many-to-many database relationships. Alongside database modeling tools, it provides basic flowchart shapes and block arrows for general system diagramming. Core Functionality: Database Design Canvas: Open a responsive workspace to place nodes, align elements, and structure your database schema. Entity Relationship Shapes: Use standard industry notations to define tables, primary keys, foreign keys, and exact table connections. Custom Image Support: Import reference images from your device storage or capture them using your camera to add external context to your diagrams. Export Options: Save your completed database models as high-resolution PNG images or PDF documents for documentation and sharing. Project Management: Organize multiple database designs in a structured dashboard. Deleted diagrams are moved to a temporary trash bin and retained for 30 days before permanent removal. Tablet Layout: The user interface automatically adapts to larger screens, providing an expanded grid view necessary for mapping out complex database systems. Whether you are building a relational database for a new software project or documenting an existing system schema, ER Diagram Maker gives you the specific technical components needed to map out data structures clearly. The application focuses strictly on essential diagramming utilities, ensuring that your system design process remains practical and direct.
