InteGrate

InteGrate 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 InteGrate rather than just read about it. In short: IntegRate was a software product written in C++ based on a pipe-lined high performance architecture for handling batch rating of telecommunications using call detail records (CDR), developed by the German software company Solution 42. Description The product was an early massively parallel application.

Key takeaways

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

Reference excerpt

IntegRate was a software product written in C++ based on a pipe-lined high performance architecture for handling batch rating of telecommunications using call detail records (CDR), developed by the German software company Solution 42.

Description The product was an early massively parallel application. It processed and charge thousands of events per second on commodity hardware. The software was able to run on the following operating systems: Windows, Unix/Linux, Solaris, HP-UX and AIX. It contained algorithms for ultra-fast regular expression matching using a finite-state machine as well as one of the first in-memory databases. IntegRate platform is a conceptual structure for performing the complex task of telecommunications rating and price modeling. The "framework" contains "pipelines", each of which consists of "plug-ins", which can be freely combined. The standard plug-ins cover rating tasks (e.g. zoning, service determination) and the overall rating process can be customized by using the IntegRate script languages "iScript" and "iRule". This allows configuring plug-in modules to prepare or post-process CDR-information. Solution42 (a name taken from Douglas Adams's "Hitchhikers Guide to the Galaxy" cult series), originally based in Quickborn, Germany, was purchased by Portal Software in 2000. Since the purchase of Solution42, the IntegRate architecture was integrated into the so-called "Portal Infranet " telecommunications billing platform, now called the Batch Rating Engine (BRE). In 2006 Oracle Corporation acquired Portal Software. IntegRate became the central rating and mediation engine with Oracle's CBRM System. In 2003 the core engineers and lead architects of former Solution42 founded ENTEREST to build the successor product "EDR Workbench" marketed for complex event processing using the marketing term big data.

Worked examples

Example 1 — a first encounter with InteGrate

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

In research: InteGrate 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 InteGrate 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: InteGrate is common in secondary-school and first-year university syllabi. It links to neighbouring topics Telephony software, Telephony stubs, so understanding it makes those chapters shorter.
In everyday life: Look for InteGrate 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 InteGrate in simple terms?

Why does InteGrate 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 InteGrate?

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.
