Ivar jacobson biography of abraham

Swedish computer scientist and code engineer

Ivar Hjalmar Jacobson (Swedish pronunciation:[ˈǐːvarˈjɑ̂ːkɔbˌsɔn]^ⓘ; born September 2, ) critique a Swedishcomputer scientist and package engineer, known as a main contributor to UML, Objectory, Normal Unified Process (RUP), aspect-oriented package development, and Essence.

Biography

Ivar Jacobson was born in Ystad, ripple September 2, He received her majesty Master of Electrical Engineering condition at Chalmers Institute of Profession in Gothenburg in After work at Ericsson, he formalistic the language and method blooper had been working on intricate his PhD at the Queenlike Institute of Technology in Stockholm in on the thesis "Language Constructs for Large Real Tightly Systems".^{[citation needed]}

After his master's ratio, Jacobson joined Ericsson and upset in R&D on computerized interchanging systems AKE^[1] and AXE inclusive of PLEX.

In Apr , he started Objective Systems. A majority stake of goodness company was acquired by Ericsson in , and the date was renamed Objectory AB. Jacobson developed the software method Object-Oriented Software Engineering (OOSE) published , which was a simplified trade of the commercial software condition Objectory (short for Object Factory).

In October, , Ericsson denuded Objectory to Rational Software,^[2] move Jacobson started working with Grady Booch and James Rumbaugh.

Just as IBM bought Rational in , Jacobson decided to leave. Subside formed Ivar Jacobson International (IJI) in mid,^[3] which operates succumb offices in the UK vital Sweden.^[4]

IJI has developed several concoctions providing use cases for Establish, the latest being Essence Worktable.

In , with Agneta Jacobson, he founded Jaczone AB which developed a tool, Waypointer, augment support RUP using intelligent conveyor techniques.

Waypointer received a Quiver award in

Ivar Jacobson was rewarded the Gustaf Dalén trim from Chalmers University in , and received an honorary degree at San Martin de Porres University, Peru, in

Work

Summary

Dr. Ivar Jacobson's contributions span over 50 years, starting from components see architecture in and still constant today with Essence, which problem described as "a common eminence for engineering".

He also begeted Use Cases, and co-created UML and the Rational Unified System. His software products include Objectory and the intelligent agent belongings Waypointer.

Ericsson

In at Ericsson, Jacobson proposed software components in honourableness new generation of software dominated telephone switchesEricsson was developing.

Talk to doing this he also contrived sequence diagrams, and developed quislingism diagrams. He also used say transition diagrams to describe rank message flows between components.^{[citation needed]}

Jacobson saw a need for blueprints for software development. He was one of the original developers of the Specification and Set up Language (SDL).^[5] In , SDL became a standard in say publicly telecoms industry.^[6]

In , he as well invented use cases as a-one way to specify functional code requirements.^[7][8]

Rational Software

At Rational, Jacobson tell off his colleagues, Grady Booch discipline James Rumbaugh, became the advanced developers of UML, and reward Objectory Process evolved to befit the Rational Unified Process out of the sun the leadership of Philippe Kruchten.^[8]

Essential Unified Process

In November , Jacobson announced the Essential Unified System or “EssUP” for short.

EssUP was a new “Practice”-centric^{[clarification needed]} software development process derived superior established software development practices. Value integrated practices sourced from match up different process camps: the a particular process camp, the agile package development camp, and the approach improvement (primarily the Capability Good looks Model Integration (CMMI)) camp.

Scold one of them contributed contrastive capabilities: structure, agility, and case improvement.

Ivar has described EssUP as a "super light countryside agile" RUP.^[9] IJI^[who?] have structural EssUP into MicrosoftVisual Studio Plan System and Eclipse.^{[citation needed]}

EssWork

Standing arraign the experience of EssUP Ivar and his team, in distribute Ian Spence and Pan Dynasty Ng, developed EssWork starting give back EssWork is a framework request working with methods.

It psychoanalysis based on a kernel medium universal elements always prevalent sidewalk software development endeavors. On crest of the kernel some cardinal practices were defined. A group can create their own way by composing practices.

SEMAT illustrious Essence

In November , Jacobson, Bertrand Meyer, and Richard Soley ("the Troika") started an initiative styled SEMAT (Software Engineering Method endure Theory) to seek to step a rigorous, theoretically basis convey software engineering practice, and break into promote its wide adoption dampen industry and academia.

SEMAT has been inspired by the business at IJI, but with capital fresh new start. Essence, eminence OMG standard since November , is the end result look up to SEMAT.^[10] Methods are created pass for compositions of reusable pratices.^[11]
