What is the bow tie symbol?
The bow tie is best known as a formal-neckwear accessory, but the term “bow tie symbol” also refers to a mathematical/logical glyph (the bowtie symbol) used to denote a join operation in relational algebra and database theory.
Contexts of the bow tie
Fashion: The bow tie as neckwear
In fashion, a bow tie is a short band around the collar tied into a bow. It comes in self-tie and pre-tied varieties and is most closely associated with formalwear such as tuxedos and black-tie events. Materials range from silk and satin to cotton, with colors and patterns that can vary from classic black to bold prints. The classic black bow tie is a staple of formal dress codes, while decorative or novelty bow ties appear at weddings, performances, and social occasions. The bow tie’s symmetrical loops and knot create a distinctive silhouette that signals a formal or traditional aesthetic.
Symbol in mathematics and database theory
In mathematics and computer science, the bow tie symbol (⋈) is used to represent a join operation between two relations in relational algebra. It most commonly denotes a natural join, where rows from two relations are combined based on all common attributes. The symbol helps convey the concept of “combining data from two sources” in formulas, diagrams, and theoretical discussions. While relational algebra often uses ⋈ in academic texts, SQL expresses joins with keywords (JOIN … ON …). Additionally, other join glyphs such as ⨝ or ⟕/⟖ can appear in some texts to indicate specific join types or variants.
Unicode and typography
The bowtie glyph is encoded in Unicode as U+22C8 and is visually rendered as the bowtie shape: ⋈. In HTML you can render it with the numeric character reference ⋈ or its decimal equivalent ⋈. This symbol is commonly included in math and database font sets, and its appearance can vary slightly depending on the font, but the meaning remains the same in scholarly contexts.
Practical usage and quick references
When you encounter the bow tie symbol in text, it typically signals a join operation in the context of relational data. In fashion or discussions of attire, it signals the neckwear item itself. If you’re typing or citing sources, you can copy the character ⋈ (U+22C8) or insert it via the code points ⋈ / ⋈. In academic writing, be aware that some authors may use similar-looking symbols like ⨝ for different join notions, so check the surrounding notation for precise meaning.
Summary
The bow tie symbol serves a dual purpose: it is a classic piece of formal neckwear that conveys a traditional, polished look, and it is also a mathematical glyph used to denote join operations between relations in relational algebra. Recognizing both meanings helps readers interpret discussions in clothing, mathematics, and database theory, and knowing its Unicode encoding makes it easy to display correctly in digital texts.
What is ⋈?
The '⋈' (bow tie) symbol is used in relational algebra to denote the natural join of two relations. For example, if we have two relations R and S: R⋈S. This denotes the natural join of R and S, i.e., the set of all combinations of tuples in R and S that are equal on their common attribute names.
What does a bowtie symbol mean?
A bow tie can symbolize individuality and confidence, as it is a more unconventional and attention-grabbing accessory than a standard necktie. It is also associated with intelligence, sophistication, and formality, especially in academic or professional settings, and can convey a professorial or distinguished air.

- Individuality and confidence: Wearing a bow tie often signals a willingness to stand out and be different. It suggests a confident embrace of a unique style.
- Intelligence and sophistication: Due to its association with formal wear and intellectuals, a bow tie can suggest intelligence and sophistication. It is a standard for certain events, like a "black tie" dress code, and can be associated with professions like academics or law.
- Formality and tradition: Bow ties have a long history and are a staple of formal attire, particularly for events like weddings or galas. They can be seen as a symbol of classic style and tradition.
- Eccentricity: While it can be a sign of sophistication, the bow tie is sometimes also associated with eccentricity, similar to a "nerd" or "professorial" look, as seen with characters like Dexter from Dexter's Laboratory.
- Southern charm: In certain contexts, a bow tie is seen as a symbol of Southern elegance and grace.
- Power: Historically, ties and other neckwear have symbolized rank, and today a bow tie can project an image of power and leadership.
