OSIsoft

OSIsoft is a computer 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 OSIsoft rather than just read about it. In short: OSIsoft, LLC was a manufacturer of application software for real-time data management, called the PI System. Founded in 1980, OSIsoft was privately held and headquartered in San Leandro, California.

Key takeaways

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

Reference excerpt

OSIsoft, LLC was a manufacturer of application software for real-time data management, called the PI System. Founded in 1980, OSIsoft was privately held and headquartered in San Leandro, California. In August 2020, it was announced that the UK-based production company AVEVA agreed to buy OSIsoft in a deal worth $5 billion; the purchase was subsequently completed on 19 March 2021 for a final consideration of £3,831.4 million.

History On January 5, 2011, OSIsoft announced a $135 million minority investment by Technology Crossover Ventures and Kleiner Perkins Caufield & Byers. Lit San Leandro, a business associated with OSIsoft, has built a fiber-optic network in the city of San Leandro, linking high tech and other businesses. They have also proposed providing a high-speed fiber-optic network for the industrial corridor in nearby Hayward.

Worked examples

Example 1 — a first encounter with OSIsoft

Start with the simplest possible case. Write down what OSIsoft claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer 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 OSIsoft 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 OSIsoft 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 OSIsoft

In research: OSIsoft appears in computer 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 OSIsoft 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: OSIsoft is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1980 establishments in California, 2021 mergers and acquisitions, Companies based in San Leandro, California, so understanding it makes those chapters shorter.
In everyday life: Look for OSIsoft 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 OSIsoft in simple terms?

OSIsoft, LLC was a manufacturer of application software for real-time data management, called the PI System. Founded in 1980, OSIsoft was privately held and headquartered in San Leandro, California.

Why does OSIsoft matter?

Because it connects several computer 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 OSIsoft?

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.
