Global information system

Global information system is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Global information system rather than just read about it. In short: Global information system is an information system which is developed and / or used in a global context. Some examples of GIS are SAP, The Global Learning Objects Brokered Exchange and other systems.

Key takeaways

Global information system belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Global information system to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Global information system from memory before moving on to harder problems.

Reference excerpt

Global information system is an information system which is developed and / or used in a global context. Some examples of GIS are SAP, The Global Learning Objects Brokered Exchange and other systems.

Definition There are a variety of definitions and understandings of a global information system (GIS, GLIS), such as

A global information system (GIS) is an information system which is developed and / or used in a global context. A global information system (GIS) is any information system which attempts to deliver the totality of measurable data worldwide within a defined context. Common to this class of information systems is that the context is a global setting, either for its use or development process. This means that it highly relates to distributed systems / distributed computing where the distribution is global. The term also incorporates aspects of global software development and there outsourcing (when the outsourcing locations are globally distributed) and offshoring aspects. A specific aspect of global information systems is the case (domain) of global software development. A main research aspect in this field concerns the coordination of and collaboration between virtual teams. Further important aspects are the internationalization and language localization of system components.

Tasks in designing global information systems Critical tasks in designing global information systems are

Process and system design: How are the processes between distributed actors organized, how are the systems distributed / integrated. Technical architecture: What is the technical infrastructure enabling actors to collaborate? Support mechanisms: How are actors in the process of communication, collaboration, and cooperation supported? A variety of examples can be given. Basically every multi-lingual website can be seen as a global information system. However, mostly the term GLIS is used to refer to a specific system developed or used in a global context.

Examples Specific examples are

Systems developed for multinational users, e.g., SAP as a global ERP system Global Information Systems for Education: The Global Learning Objects Brokered Exchange For the specific case of data integration : http://data.un.org, https://web.archive.org/web/20190825060649/http://www.internettrafficreport.com/, http://www.unhcr.org/statistics.html

Worked examples

Example 1 — a first encounter with Global information system

Start with the simplest possible case. Write down what Global information system claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Global information system before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Global information system ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Global information system

In research: Global information system appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Global information system in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Global information system is common in secondary-school and first-year university syllabi. It links to neighbouring topics Information, Information systems, so understanding it makes those chapters shorter.
In everyday life: Look for Global information system outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Global information system in simple terms?

Global information system is an information system which is developed and / or used in a global context. Some examples of GIS are SAP, The Global Learning Objects Brokered Exchange and other systems.

Why does Global information system matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Global information system?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
