Information systems infrastructure: evolution and trends.

An
information system is a combination of computerized software, hardware and
infrastructure to collect, modify and save data. It can be used to process and
distribute data to designated destinations. Better communication and effect
oriented work practices are some of the outcomes of using a proper information
system. These in turn help an organization to make better decisions. The
evolution of information system has been significant over the past decades.

Information
system had functions attached with the level at which the organization used to
it. The information system function can be summarized as follows with timeline
reference:

·      
From 1950 to 1960, Data Processing: Day to day
transaction of an organizations data by collecting, storing and modifying it.

·      
From 1960 to 1970, Management Reporting:
Supporting decision making of the business by reports and displays.

·      
From 1970 to 1980, Decision Support: Supporting
decision making process by Interactive ad-hoc.

·      
From 1980 to 1990, Executive Support: Relevance
to internal and external strategy progress of the organization.

·      
From 1990 to 2000, Knowledge Management:
Supports conception, association and distribution of business knowledge.

·      
From 2000 to Present, E-Business: Better
connectivity and advanced assimilation across applications.

The
infrastructure of the Information system has mainly enhanced after the arrival
of the first computers after the 1960s. Now the activities of managing,
assembling, organizing, modifying and distributing data was assisted by
technological tools.

The
development of infrastructure of information system progressed and evolved from
a mainframe phase (1960-1970) to client server phase (1980-1990), to web based
client-server (late 1990s) finally to distributed component phase or the
internet phase (2000 and beyond).

The
mainframe computing built on centralized computing resources. The client-server
infrastructure distributes computing with use of network systems. The evolving module
architecture based itself on Internet computing. The positioning of
client-server and component-based initiative system pressurized the resources
of the server like the security, data center and the bandwidth. The trends in
infrastructure of information system were recognized to be affected by the
advancement in the technology of the era.

How the
two articles are related to the topic?

The articles have been tied together by the timeline
of how function and infrastructure evolved and seem to have influenced each
other’s trends. Consider the evolution of the main functions or need of
information system and how the functions evolved with the technological
evolution; thus, connecting to how the information system infrastructures
development came to existence which can be mapped with the reference of
timelines showing the evolution trends. The first article mentions the change
in functions of the information system and the second one shows how the
infrastructure of the system changes with time. The technological advancements
and activities involved evolve with the system change with thus effect the
infrastructure of the overall information system.
