(Institutional Affiliation) FORMAL REPORT COMPARING THE USE OF THE IDEF METHODOLOGY TO UML - Essay Example 1). On the other hand, UML is a modeling language that is most suited to the generation of computer-executable platforms/frameworks that encode important elements of software engineering projects. This paper will seek to compare the use of IDEF to UML by focusing on their applications, nature, and techniques employed in their development. This comparison will be done on the basis of credible and reliable literatures, written and published by authorities on modeling languages and techniques. Key Words IDEF; UML; graphical modeling methods; enterprise engineering projects; modeling language The Approach/Rationale of both Methodologies a) IDEF According to Bernus, Mertins, & Schmidt (1998, pg. 17), the rationale for IDEF is to support modeling activities that are fundamental to system analysis, design, improvement or integration. b) UML The approach/rationale for UML is to act as the dominant, publicly accepted, and uniform objected oriented visual modeling language, and as a foundation object description language for the offshoot unified enterprise modeling language (UEML) that has been put forward by IFAC/IFIP (Bernus, Mertins, & Schmidt 1998, pg. 17). The Stages of the Systems Development Life Cycle that each Addresses IDEF methodology addresses documentation, design, integration, analysis, understanding, planning, and improvement (Fowler & Scott 2000, pg. 46). Based on the Waterfall model of the system development life cycle (SDLC), these functions fit into four stages of the SDLC: preliminary analysis, system analysis and requirements definition, systems design, integration and testing, and maintenance. On the other hand UML methodology is limited to the systems design phase. During the systems analysis phase, object-oriented analysis (OOA) is performed; its output is a conceptual model that is comprised of one (sometimes more) UML class diagram, a user-interface mock-up, a group of use cases, and a couple of interaction diagrams. This conceptual model is sub sequently used as an input in objected-oriented design during the systems design phase (Lankhorst 2005, pg. 63). The Techniques used for modeling the Processes/Functions of the System (including the similarities and differences between the techniques and their strengths and weaknesses) a) IDEF Techniques IDEF is based on three modeling constructs/viewpoints/techniques which define its approach/rationale. These are: i) IDEF0 Function Modeling Method This method was created so as to represent processes or activities (consisting of partially sequenced groups of activities) that are usually executed in a systematic and uniform manner. IDEF0 defines a function as a group of activities that takes specific inputs and, using some mechanism, and based on certain controls, converts the inputs into outputs (Noran 2008, pg. 41). These ICOMs (inputs, controls, outputs and mechanisms) can be employed in the modeling of relationships between a wide range of activities (Kim 2003, pg. 3). IDEF0 mode ling generally begins by defining a context diagram (Kim 2003, pg. 3). This is representative of the system’s overall purpose and its interactions with external environments (Kim 2003, pg. 3). Usually, IDEF0 models consist of a hierarchy of connected diagrams that are decomposed systematically hence encoding semantic data at lower modeling levels. The systematical breakdown brings not only detailed but also wide-scope representations of system or environmental activities (Bernus, Mertins, & Schmidt 1998, pg. 29). ii) IDEF1x Data Modeling Method This method was created to define data models that symbolize both the semantics and structure of data that is found in a target system

Black Feminism and The Beyonce Wars - Essay Example The first article ‘Ugly Internal Clash: Why Its Future Is Not Up To White Women’ talks about feminism especially for black women and how they can form a gender inclusive group to deal with racism, sexual harassment, and work discrimination against women. The article provides a name that helps women to describe the issues they go through during discrimination Brittney (Cooper 2015). Feminism is the name, and it helps many women to discuss their issues without language challenges. Black women use the internet feminism to air their troubles and discuss the discrimination that they experience. The women also express their power through it phenomena that make the white women extremely uncomfortable. The writers opinion is that the future of feminism should not be left with the white women as most of the issues center around gender equality. For white women, equality was achieved a long time ago, but for the black women, it is still a big issue. Most of the black women in the US do not fully access some of the benefits, such as the Obamacare in some states (Cooper 2015). Understanding feminist and black women oppression will help women fight for their rights in foreign countries, such s the United States. The second article ‘Black Feminist Blogger Speaks The Truth by Goldstein, Rich talks about how important issues contributed by black women in the media get ignored by many readers and viewers. The writer focuses on blogs on issues of life for black women instead of focusing on wealthy and glamorous women in power (Goldstein 2015). According to the blog, there are many interesting things about black women, such as their unique talents, although there are few people who recognize them. Racism is real and classifies women according to their place of origin, and the blog help many to have some attention on racism, sexism, and ableism. The writer admires the work of Beyonce for focusing on feminism, especially the one touching on black women. Black women
