UML Tutorial: Part 1 -- Class Diagrams
UML Tutorial: Part 1 -- Class Diagrams. Robert C. Martin My next several columns will be a running tutorial of UML. The 1.0 version of UML was released on the 13th of January, 1997. The 1.1 release should be out before the end of the year. This col- umn will track the progress of UML and present the issues that the three amigos (Grady Booch, Jim Rumbaugh, and Ivar Jacobson) are dealing with. Introduction UML stands for Unified Modeling Language. It represents a unification of the concepts and nota- tions presented by the three amigos in their respective books1. The goal is for UML to become a common language for creating models of object oriented computer software. In its current form UML is comprised of two major components: a Meta-model and a notation. In the future, some form of method or process may also be added to; or associated with, UML. The Meta-model UML is unique in that it has a standard data representation. This representation is called the meta- model. The meta-model is a description of UML in UML. It describes the objects, attributes, and relationships necessary to represent the concepts of UML within a software application. This provides CASE manufacturers with a standard and unambiguous way to represent UML models. Hopefully it will allow for easy transport of UML models between tools. It may also make it easier to write ancillary tools for browsing, summarizing, and modifying UML models. A deeper discussion of the metamodel is beyond the scope of this column. Interested readers can learn more about it by downloading the UML documents from the rational web site2. -
The Timeboxing Process Model for Iterative Software Development
The Timeboxing Process Model for Iterative Software Development Pankaj Jalote Department of Computer Science and Engineering Indian Institute of Technology Kanpur – 208016; India Aveejeet Palit, Priya Kurien Infosys Technologies Limited Electronics City Bangalore – 561 229; India Contact: [email protected] ABSTRACT In today’s business where speed is of essence, an iterative development approach that allows the functionality to be delivered in parts has become a necessity and an effective way to manage risks. In an iterative process, the development of a software system is done in increments, each increment forming of an iteration and resulting in a working system. A common iterative approach is to decide what should be developed in an iteration and then plan the iteration accordingly. A somewhat different iterative is approach is to time box different iterations. In this approach, the length of an iteration is fixed and what should be developed in an iteration is adjusted to fit the time box. Generally, the time boxed iterations are executed in sequence, with some overlap where feasible. In this paper we propose the timeboxing process model that takes the concept of time boxed iterations further by adding pipelining concepts to it for permitting overlapped execution of different iterations. In the timeboxing process model, each time boxed iteration is divided into equal length stages, each stage having a defined function and resulting in a clear work product that is handed over to the next stage. With this division into stages, pipelining concepts are employed to have multiple time boxes executing concurrently, leading to a reduction in the delivery time for product releases. -

Best Practice of SOA
JOURNAL OF COMPUTING, VOLUME 2, ISSUE 2, FEBRUARY 2010, ISSN: 2151-9617 38 HTTPS://SITES.GOOGLE.COM/SITE/JOURNALOFCOMPUTING/ Improvement in RUP Project Management via Service Monitoring: Best Practice of SOA Sheikh Muhammad Saqib1, Shakeel Ahmad1, Shahid Hussain 2, Bashir Ahmad 1 and Arjamand Bano3 1Institute of Computing and Information Technology Gomal University, D.I.Khan, Pakistan 2 Namal University, Mianwali , Pakistan 3 Mathematics Department Gomal University, D.I.Khan, Pakistan Abstract-- Management of project planning, monitoring, scheduling, estimation and risk management are critical issues faced by a project manager during development life cycle of software. In RUP, project management is considered as core discipline whose activities are carried in all phases during development of software products. On other side service monitoring is considered as best practice of SOA which leads to availability, auditing, debugging and tracing process. In this paper, authors define a strategy to incorporate the service monitoring of SOA into RUP to improve the artifacts of project management activities. Moreover, the authors define the rules to implement the features of service monitoring, which help the project manager to carry on activities in well define manner. Proposed frame work is implemented on RB (Resuming Bank) application and obtained improved results on PM (Project Management) work. Index Terms—RUP, SOA, Service Monitoring, Availability, auditing, tracing, Project Management NTRODUCTION 1. I 2. RATIONAL UNIFIED PROCESS (RUP) Software projects which are developed through RUP RUP is a software engineering process model, which provides process model are solution oriented and object a disciplined approach to assigning tasks and responsibilities oriented. It provides a disciplined approach to within a development environment. -

Sysml Distilled: a Brief Guide to the Systems Modeling Language
ptg11539604 Praise for SysML Distilled “In keeping with the outstanding tradition of Addison-Wesley’s techni- cal publications, Lenny Delligatti’s SysML Distilled does not disappoint. Lenny has done a masterful job of capturing the spirit of OMG SysML as a practical, standards-based modeling language to help systems engi- neers address growing system complexity. This book is loaded with matter-of-fact insights, starting with basic MBSE concepts to distin- guishing the subtle differences between use cases and scenarios to illu- mination on namespaces and SysML packages, and even speaks to some of the more esoteric SysML semantics such as token flows.” — Jeff Estefan, Principal Engineer, NASA’s Jet Propulsion Laboratory “The power of a modeling language, such as SysML, is that it facilitates communication not only within systems engineering but across disci- plines and across the development life cycle. Many languages have the ptg11539604 potential to increase communication, but without an effective guide, they can fall short of that objective. In SysML Distilled, Lenny Delligatti combines just the right amount of technology with a common-sense approach to utilizing SysML toward achieving that communication. Having worked in systems and software engineering across many do- mains for the last 30 years, and having taught computer languages, UML, and SysML to many organizations and within the college setting, I find Lenny’s book an invaluable resource. He presents the concepts clearly and provides useful and pragmatic examples to get you off the ground quickly and enables you to be an effective modeler.” — Thomas W. Fargnoli, Lead Member of the Engineering Staff, Lockheed Martin “This book provides an excellent introduction to SysML. -
Component Diagrams
1.COMPONENT DIAGRAMS 2. PACKAGE DIAGRAMS What is a component? – A component is an autonomous unit within a system – UML component diagrams enable to model the high-level software components, and the interfaces to those components – Important for component-based development (CBD) – Component and subsystems can be flexibly REUSED and REPLACED – UML components diagrams are Implementation diagrams i.e., it describe the different elements required for implementing a system Example – When you build a house, you must do more than create blueprints – you've got to turn your floor plans and elevation drawings into real walls, floors, and ceilings made of wood, stone, or metal. – If you are renovating a house, you'll reuse even larger components, such as whole rooms and frameworks. – Same is the case when we develop software…. COMPONENT NOTATION – A component is shown as a rectangle with – A keyword <<component>> – Optionally, in the right hand corner a component icon can be displayed – A component icon is a rectangle with two smaller rectangles jutting out from the left-hand side – This symbol is a visual stereotype – The component name Component types Components in UML could represent – logical components (e.g., business components, process components) – physical components (e.g., EJB components, COM+ and .NET components) Component ELEMENTS – A component can have – Interfaces An interface represents a declaration of a set of operations – Usage dependencies A usage dependency is relationship which one element requires another element for its full -

Ovum Decision Matrix: Selecting an Application Lifecycle Management and Devops Solution, 2019–20
Ovum Decision Matrix: Selecting an Application Lifecycle Management and DevOps Solution, 2019–20 Publication Date: 27 Jun 2019 | Product code: INT003-000374 Michael Azoff Ovum Decision Matrix: Selecting an Application Lifecycle Management and DevOps Solution, 2019–20 Summary Catalyst Software lifecycle management (SLM) is the management of software development by taking a lifecycle approach from concept through the management of requirements, testing, coding, deployment, upgrades, maintenance, and final retirement. The market provides tools to support this lifecycle in the form of application lifecycle management (ALM) tools and, with the rise of DevOps, tools that provide DevOps-style release management, orchestration, and automation. This Ovum Decision Matrix (ODM) examines ALM tools that cross over into DevOps to support the full arc of the lifecycle from application/product concept to deployment into production. Ovum view ALM origins and trends The need for taking an SLM approach is best thought of as good practice in the relatively young art of software development. The ALM tools market has evolved to support SLM through the years; at its core is the development methodology or work process, and this has evolved over time, starting with waterfall or linear stage-gate processes and incorporating various innovations such as Tom Gilb's evolutionary delivery, Barry Boehm's spiral model, and Rational's unified process, before Agile and lean swept the board with examples such as Scrum, extreme programming, and Kanban boards post- 2001 (when the Agile Manifesto was created). The integrated ALM suite tools market really took off around 2003 but supported waterfall because Agile was still under the radar.
