Relation Only One To Zero Or One

The relation-only-one-to-zero-or-one icon represents a one-to-one relationship in database design, where one entity can have only one related entity, and the related entity cannot exist without the parent entity. This icon is crucial in understanding data modeling and schema design. It originates from the material design icons library, created by Pictogrammers.

In software development, this icon can be used in tools like Entity Framework, Hibernate, or other Object-Relational Mapping (ORM) tools to represent relationships between entities. It can also be used in database design software like MySQL Workbench or pgModeler to visualize database schemas.

From a UX perspective, this icon communicates the idea of a single parent entity having a single child, helping users understand complex relationships between data entities. It aids in navigation and understanding of data structures, making it easier for users to interact with databases.

Relation Only One To Zero Or One is one of 7,638 icons in Material Design Icons, made by Pictogrammers and released under Apache 2.0. It is drawn on a 24 × 24 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds RelationOnlyOneToZeroOrOneIcon to components/icons/mdi-relation-only-one-to-zero-or-one.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed RelationOnlyOneToZeroOrOneIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Relation Only One To Zero Or One icon, or any of 7,638 Material Design Icons icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Relation Only One To Zero Or One", so screen readers say what it does.

Yes. RelationOnlyOneToZeroOrOneIcon passes every SVG prop to the svg element, so <RelationOnlyOneToZeroOrOneIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes. Apache 2.0 allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.

No visible credit is required: Apache 2.0 only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming Material Design Icons, Pictogrammers and the license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.

Its tags are design, material, connection, database, relationship and diagram. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Relation Only One To Zero Or One in another set.
