The diagram emphasizes events that cross the system boundary from actors to systems. A system sequence diagram should be done for the main success scenario of the use case, and frequent or complex alternative scenarios. There are two kinds of sequence diagrams: Sequence Diagram (SD): A regular version of sequence diagram describes how the ...
Use case diagrams are used to identify the actor (users or other systems) and the processes they perform. System sequence diagram: A system sequence diagram (SSD) is a picture that shows, for a particular scenario of a use case, the events that external actors generate, their order, and possible inter-system events.
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

Integrated with building and debugging code Enterprise Architect allows the developer to perform abstract analysis of the software using profiling and sequence diagram generation: Sequence diagram generation provides a means to analyze the general process flow and iron out inconsistencies, [36] and Profiling summarizes, by thread and routine ...
In the e-commerce example, the controller determines the sequence of web pages in the checkout sequence, and is also responsible for validating that email, address, and payment information satisfy the business rules (rather than leaving any of that up to the database itself or lower-level database access code). Alternative paradigms are possible.
The E-Government Act of 2002, Section 208, establishes the requirement for agencies to conduct privacy impact assessments (PIAs) for electronic information systems and collections. The assessment is a practical method of evaluating privacy in information systems and collections, and documented assurance that privacy issues have been identified ...
Authorization is the process of giving someone permission to do or have something. In multi-user computer systems, a system administrator defines for the system which users are allowed access to the system and what privileges of use (such as access to which file directories, hours of access, amount of allocated storage space, and so forth).
An encyclopaedic review of PIM literature suggests that all six senses of personal information listed above and the tools and technologies used to work with such information (from email applications and word processors to personal information managers and virtual assistants) combine to form a personal space of information (PSI, pronounced as in the Greek letter, alternately referred to as a ...
