A diagram showing the flow of activities. Used to give a high-level view of a business process.
An external person or system that interfaces with (that is, uses or is used by) the system. Depicts a user's logical role.
A relationship between model elements indicating that one element is a 損art of?another element (aggregate).
American National Standards Institute.
A relationship between two model elements.
A class that embodies properties of an association (typically an association between two other classes).
The properties of a class.
An actor that is external to the business.
Something used by a business worker while fulfilling a use case.
A model that describes the business operation. The business model is composed of the business use case model and the business object model.
An object model that provides the realization of a business use case. An internal view of the business.
A use case, initiated by a business actor, that the business performs.
A use case model that describes the business functions from a business actor's point of view. An external view of the business.
An actor that is internal to the business whose work helps realize a business use case.
A column or set of columns that uniquely identifies a row in a table.
A diagram that shows classes, their interrelationships, and their relationships with other model elements. The intent is to show the basic structure of the system.
A diagram for database design that depicts physical storage of the database, including the DBMS, tablespaces, and partitions. Can also include applications and their interfaces to each other and to database elements.
A very high-level model of a system or database. Typically this model contains high-level domain entities and their basic relationships with other major domain entities. Its main purpose is to define the scope of the system. This model should be technology independent.
A rule that limits the value of or actions on the specified data field.
An active class that controls the behavior of one or more other classes.
When referring to databases, a file or files that contain in formation describing the data in the database; also called a system catalog.
A collection of information.
A diagram depicting the structure of the database, including tables, columns, constraints, and so on.
Database management system.
Data Definition Language.
A process applied to a database schema that reduces its level of normalization. Used to improve the operational effectiveness (for example, simplified access, better performance, and so on) of the database.
A diagram depicting the hardware configuration that is used for the database and applications.
An attribute whose value is determined by the value of other attributes.
The valid set of values for an attribute or column.
An object in the business or system.
A diagram depicting entities and their relationships with each other.
Entity-relationship.
A stereotype of a relationship that indicates an optional use case flow that may be executed, based on specific criteria.
Location in the flow of events of a use case where the use case is extended by another use case.
A column or set of columns within a table that map to the primary key of another table.
An approach to systems development in which the larger system is broken down into smaller parts. Those parts may then be broken down into even smaller parts, and so on. Each part of the system that is so decomposed is an aggregate of its smaller parts.
A relationship between model elements indicating that one element (subclass) is a 搕ype of?another element (superclass).
A relationship between two tables in which the child table must coexist with the parent table.
A stereotype of a relationship that indicates a use case flow that is inserted into another use case or use cases.
Location in the flow of events of a use case where another use case is inserted into the flow of the original use case.
A file that enables faster data access.
The mechanism by which more-specific elements incorporate the structure and behavior of more general elements.
Sequence and/or collaboration diagrams, both of which show the interaction of objects within the system. Can be used to understand queries that will affect the database and even build indexes based on the information modeled.
A process whereby the primary key of a table is added as a foreign key to a related table.
An analysis/design-level model of a system or database. Its main purpose is to define architecture and overall design of the system.
Minimum Data Set. A standard collection of information about a resident who is being cared for in a healthcare facility.
A relationship between two tables in which each table can exist independently of the other.
An analytical technique used to produce a correct relational database design.
A UML element used to group other elements together.
A division of storage space.
A class that is not active and does not embody any control of the system.
A detailed implementation-level model of a system or database. Its main purpose is to define the specific, detailed implementation of the system.
Possible states of the system that exist after the execution of a use case.
The required state of the system, or conditions that must be true, for a use case to be executed.
The candidate key that is chosen to identify rows in a table.
An extension to the UML that uses stereotypes and tagged values to extend the UML for specialized purposes while keeping the UML metamodel intact.
Relational database management system.
A rule that states if a foreign key exists in a table, its value must be null or must also appear in a related table's candidate key.
An association between tables.
A statement describing a desired capability of the system.
A set of behaviors of an element specific to its interaction with other elements in a given situation.
A description of a database's structure.
A diagram of collaborating objects and the messages they send to each other arranged in time order. Sequence diagrams show how use cases are realized.
Structured Query Language.
A diagram that captures the dynamic behavior of a class or part of the system.
A specialized version of a standard UML element.
An independent procedural function that typically executes on the server.
A vertical delimiter on an activity diagram used to partition the activities performed by specific responsible parties.
A construct representing an amount of storage space that is to be allocated to tables, indexes, and so on.
Allows additional information about a standard UML element to be specified.
An operation or series of operations applied against a database.
A procedural function designed to execute when a table is modified.
Unified Modeling Language.
A complete flow of actions initiated by an actor that the system performs, which provide value to that actor.
A diagram that shows use cases and their relationships with actors and other use cases. The use case model is a model of the system's intended functions and its environment, which supports the business processes. This model serves as a contract between the customer and the developers.
A virtual table that, from the user's perspective, behaves exactly like a typical table but has no independent existence of its own.
