See spatial entity.
a conceptual element from the application domain, characterized by a set of attributes
a spatial phenomenon of a defined type that has at least one key attribute value different from the corresponding attribute values of surrounding phenomena
to the entities category belong desultory objects, spatially marked by well-defined boundaries and, in case, characterized by specific attributes. Examples of entity are the subdivision of the territory in normative areas or the descriptive graph of a transports infrastructure network.
An group of items about which data is stored; for example `stone' or `site'. Entities are usually represented by a table or relation with one or more attributes; an entry in the table, a particular stone, is an instance.
The attribute value is the name of an entity. When providing the attribute value, do not supply the entity reference delimiters & and ;.
An abstract type of object, the instances of which can be mapped into a relational table, i.e. a table containing a header consisting of a set of attributes, and a body consisting of a variable set of tuples (rows with values for the attributes). Duplicate tuples or attributes are not allowed. The term Entity as used here corresponds to Entity-Set in Chen (1976) and to Entity-Type in MicroTool (1995).
A “something” in which the business is interested and about which information is to be recorded – e.g. Product, Order, Bank Account. Each will have attributes like product description, order date, account limit. Appears on Logical Data Structure diagrams and are cross referenced to datastores.
An individual, manageable piece of a network; has attributes that describe it, a name that identifies it, and an interface that supports management operations.
Something that exists as independent, distinct or self-contained. For programs, it may be anything that can be described using data, such as an employee, product, or invoice. Data associated with an entity are called attributes. A product's price, weight, quantities in stock, and description all constitute attributes. It is often used in describing distinct business organizations or government agencies.
