SAP BI Accelerator

SAP BI Accelerator 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 SAP BI Accelerator rather than just read about it. In short: In computing, the SAP BW Accelerator is a computer appliance - preinstalled software on predefined hardware - which is used to speed up OLAP queries. The software was initially known as the BI Accelerator.

Key takeaways

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

Reference excerpt

In computing, the SAP BW Accelerator is a computer appliance - preinstalled software on predefined hardware - which is used to speed up OLAP queries. The software was initially known as the BI Accelerator. SAP BW Accelerator includes indexes that are vertically inverted reproductions of all the data included in InfoCubes (i.e., fact and dimension tables as well as master data). Note that there is no relational or other database management systems in BW Accelerator. There is only a file system, and indexes are essentially held as flat files. The second primary component of SAP BW Accelerator is the engine that processes the queries in memory - it uses the SAP TREX search engine. The software is running on an expandable rack of blade servers. The operating system used for BW Accelerator is 64-bit SUSE Linux Enterprise Server (SLES).

Hardware partners The software is optimized for specific hardware and operating system combinations. The list of partners which deliver the appliance is:

Worked examples

Example 1 — a first encounter with SAP BI Accelerator

Start with the simplest possible case. Write down what SAP BI Accelerator 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 SAP BI Accelerator 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 SAP BI Accelerator 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 SAP BI Accelerator

In research: SAP BI Accelerator 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 SAP BI Accelerator 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: SAP BI Accelerator is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computing stubs, Online analytical processing, so understanding it makes those chapters shorter.
In everyday life: Look for SAP BI Accelerator 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 SAP BI Accelerator in simple terms?

Why does SAP BI Accelerator 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 SAP BI Accelerator?

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.
