A use case is a tool for identifying the business goals of a system. The identification of use cases helps define system scope, ensuring that the requirements to be found will all be aligned with the business values, needs and strategy.

A sequence diagram is an interaction diagram that emphasizes the time-ordering of messages. It depicts the objects and classes involved in the scenario and the sequence of messages exchanged between the objects needed to carry out the functionality of the scenario. Typically, you’ll use one sequence diagram to specify a use case’s main flow, and variations of that diagram to specify a use case’s exceptional flows.

A deployment diagram is a diagram that shows the configuration of run time processing nodes and the components (hardware, software & middleware on hardware) that live on them that is used to model the static deployment view of a system (topology of the hardware).

Activity Diagrams describe how activities are coordinated to provide a service which can be at different levels of abstraction. Typically, an event needs to be achieved by some operation, particularly where the operation is intended to achieve a number of different things that require coordination, or how the events in a single use case relate to one another, in particular, use cases where activities may overlap and require coordination. It is also suitable for modeling how a collection of use cases coordinate to create a workflow for an organization.
