Introduction to systems analysis and design

A systems analyst , also known as business technology analyst, is an information technology IT professional who specializes in analyzing, designing and implementing information systems. Systems analysts assess the suitability of information systems in terms of their intended outcomes and liaise with end users, software vendors and programmers in order to achieve these outcomes.

Systems analysts may serve as change agents who identify the organizational improvements needed, design systems to implement those changes, and train and motivate others to use the systems.

Although they may be familiar with a variety of programming languages, operating systems, and computer hardware platforms, they do not normally involve themselves in the actual hardware or software development.

They may be responsible for developing cost analysis, design considerations, staff impact amelioration, and implementation timelines. A systems analyst is typically confined to an assigned or given system and will often work in conjunction with a business analyst. These roles, although having some overlap, are not the same.

A business analyst will evaluate the business need and identify the appropriate solution and, to some degree, design a solution without diving too deep into its technical components, relying instead on a systems analyst to do so. A systems analyst will often evaluate and modify code as well as review scripting. Some dedicated professionals possess practical knowledge in both areas business and systems analysis and manage to successfully combine both of these occupations, effectively blurring the line between business analyst and systems analyst.

The systems development life cycle SDLC is the traditional system development method that organizations use for large-scale IT Projects.

The SDLC is a structured framework that consists of sequential processes by which an information system is developed. Once a development project has the necessary approvals from all participants, the systems analysis stage begins. System analysis is the examination of the business problem that organizations plan to solve with an information system. The main purpose of the systems analysis stage is to gather information about the existing system in order to determine the requirements for an enhanced system or a new system.

The end product of this stage, known as the deliverable, is a set of system requirements. Perhaps the most difficult task in system analysis is identifying the specific requirements that the system must satisfy.

These requirements often are called user requirements because users provide them. When the system developers have accumulated the user requirements for the new system, they proceed to the system design stage.

A computer systems analyst is an occupation in the field of information technology. A computer systems analyst works to solve problems related to computer technology. Many analysts set up new computer systems, both the hardware and software , add new software applications to increase computer productivity.

Others act as system developers or system architects, but most analysts specialize in a specific type of system such as business systems , accounting systems , financial systems , or scientific systems.

As of , the sectors employing the greatest numbers of computer systems analysts were state government, insurance, computer system design, professional and commercial equipment, and company and enterprise management. The number of jobs in this field is projected to grow from , as of to , by This job ranked third best in a survey, [3] fifth best in the survey, 9th best in the survey and the 10th best in the survey.

He знаю. Но уж определенно не здесь! - Он улыбнулся.  - Может, все-таки чего-нибудь выпьете. Беккер понимал, что, по мнению бармена, ведет себя странно. - Quiere Vd.

И все был подписаны одинаково: Любовь без воска. Она просила его открыть скрытый смысл этих слов, но Дэвид отказывался и только улыбался: Из нас двоих ты криптограф. Главный криптограф АНБ испробовала все - подмену букв, шифровальные квадраты, даже анаграммы. Она пропустила эти слова через компьютер и поставила перед ним задачу переставить буквы в новую фразу. Выходила только абракадабра. Похоже, не один Танкадо умел создавать абсолютно стойкие шифры.

Сьюзан, больше не в силах сдержать слезы, разрыдалась. - Да, - еле слышно сказала .

В его ушах звучали слова Стратмора: Не звони, пока не добудешь кольцо. Внезапно он почувствовал страшный упадок сил. Если Меган продала кольцо и улетела, нет никакой возможности узнать, где оно. Беккер закрыл глаза и попытался сосредоточиться. Итак, каков следующий шаг.

 Местная валюта, - безучастно сказал пилот. - Я понимаю.  - Беккер запнулся.  - Но тут… тут слишком. Мне нужны только деньги на такси.

 Постараюсь быть краткой, - улыбнулась Сьюзан Флетчер.  - Пожалуйста. Через десять минут Беккер уже сидел в буфете АНБ, жуя сдобную булку и запивая ее клюквенным соком, в обществе очаровательной руководительницы Отделения криптографии АНБ.

Пока этого, по-видимому, не случилось: цифра 16 в окне отсчета часов заставила бы его завопить от изумления. Сьюзан допивала уже третью чашку чая, когда это наконец произошло: компьютер пискнул. Пульс ее участился.

Уже направляясь к двери, она увидела свое фото на доске объявлений и едва не лишилась чувств. На фотографии она была изображена наклонившейся над постелью, в одних трусиках. Как выяснилось, кто-то из криптографов сосканировал фотографию из порножурнала и приставил к телу головы модели голову Сьюзан. Получилось очень даже правдоподобно. К несчастью для того, кто это придумал, коммандер Стратмор не нашел в этой выходке ничего забавного.

Ей хотелось убежать, но сильные руки тянули ее. - Я люблю тебя, - шептал коммандер.  - Я любил тебя. У нее свело желудок.
