JackBe

JackBe 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 JackBe rather than just read about it. In short: JackBe Corporation was a privately held vendor of enterprise mashup software for real-time intelligence applications. In August 2013 JackBe was acquired by Software AG.

Key takeaways

JackBe 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 JackBe to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of JackBe from memory before moving on to harder problems.

Reference excerpt

JackBe Corporation was a privately held vendor of enterprise mashup software for real-time intelligence applications. In August 2013 JackBe was acquired by Software AG. JackBe's flagship product is platform called Presto, which is used for enterprise mashups, business management dashboards, and real-time intelligence applications.

Products JackBe’s main product, Presto, is an enterprise mashup platform. Presto provides real-time intelligence through functionality for self-service, on-demand data integration, and business dashboards. JackBe launched a cloud computing-based version of its Presto product in March 2010. It is hosted on Amazon EC2. Jackbe launched Mashup Sites for SharePoint (MSS) in July 2010 Jackbe announced an Enterprise App Depot in 2010, as a platform for creating internal application directories. The Enterprise App Depot is aimed at non-developers (business users), allowing them to create new business applications and then share the applications with other users.

Worked examples

Example 1 — a first encounter with JackBe

Start with the simplest possible case. Write down what JackBe 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 JackBe 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 JackBe 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 JackBe

In research: JackBe 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 JackBe 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: JackBe is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2013 mergers and acquisitions, Business intelligence companies, Defunct software companies of the United States, so understanding it makes those chapters shorter.
In everyday life: Look for JackBe 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 JackBe in simple terms?

JackBe Corporation was a privately held vendor of enterprise mashup software for real-time intelligence applications. In August 2013 JackBe was acquired by Software AG.

Why does JackBe 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 JackBe?

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.
