Types of Information System

Why are there different types of Information System?

In the early days of computing, each time an information system was needed it was ‘tailor made’ – built as a one-off solution for a particular problem. However, it soon became apparent that many of the problems information systems set out to solve shared certain characteristics. Consequently, people attempted to try to build a single system that would solve a whole range of similar problems. However, they soon realized that in order to do this, it was first necessary to be able to define how and where the information system would be used and why it was needed. It was then that the search for a way to classify information systems accurately began.

ITIL

ITIL, formerly known as the Information Technology Infrastructure Library, is a set of practices for IT service management (ITSM) that focuses on aligning IT services with the needs of business. In its current form (known as ITIL 2011 edition), ITIL is published as a series of five core volumes, each of which covers a different ITSM lifecycle stage. Although ITIL underpins ISO/IEC 20000 (previously BS15000), the International Service Management Standard for IT service management, there are some differences between the ISO 20000 standard and the ITIL framework.

ITIL describes processes, procedures, tasks, and checklists which are not organization-specific, but can be applied by an organization for establishing integration with the organization’s strategy, delivering value, and maintaining a minimum level of competency. It allows the organization to establish a baseline from which it can plan, implement, and measure. It is used to demonstrate compliance and to measure improvement.

Since July 2013, ITIL has been owned by AXELOS Ltd, a joint venture between HM Cabinet Office and Capita Plc. AXELOS licenses organisations to use the ITIL intellectual property, accredits licensed Examination Institutes, and manages updates to the framework.

Acquiring the Audio

No matter what software you choose to help create and produce your podcasts, you will first have to get your audio into the computer. How you choose to do this is entirely up to you, but is likely to depend on what level of audio quality you want and your budget. At the most basic level you could use your computer’s in-built microphone, but for a reasonable degree of quality you will want a semi-decent external microphone.

ggplot2

ggplot2 is a data visualization package for the statistical programming language R. Created by Hadley Wickham in 2005, ggplot2 is an implementation of Leland Wilkinson‘s Grammar of Graphics—a general scheme for data visualization which breaks up graphs into semantic components such as scales and layers. ggplot2 can serve as a replacement for the base graphics in R and contains a number of defaults for web and print display of common scales. Since 2005, ggplot2 has grown in use to become one of the most popular R packages.[1][2] It is licensed under GNU GPL v2.[3]

On 2 March 2012, ggplot2 version 0.9.0 was released with numerous changes to internal organization, scale construction and layers.[4] An update dealing primarily with bug fixes was released on 9 May 2012, incrementing the version to 0.9.1.[5]

On 25 February 2014, Hadley Wickham formally announced that “ggplot2 is shifting to maintenance mode. This means that we are no longer adding new features, but we will continue to fix major bugs, and consider new features submitted as pull requests. In recognition this significant milestone, the next version of ggplot2 will be 1.0.0”.[6]
