Entities can be broadly categorized into different types based on their nature and context. In business, entities include sole proprietorships, partnerships, limited liability companies (LLCs), corporations, and cooperatives, each with unique legal and tax implications. In databases, entities represent objects or concepts that data is stored about, such as customers, products, or transactions. In linguistics and natural language processing (NLP), entities are classified as named entities like people, organizations, locations, dates, and numerical values. From a legal perspective, entities can be natural persons (individuals) or artificial/juridical persons (companies or institutions). Each type serves specific purposes within its domain.
