PASCAL (database)

PASCAL (database) 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 PASCAL (database) rather than just read about it. In short: PASCAL is a scientific bibliographic database, which is maintained by INIST (CNRS). PASCAL covers the core scientific literature in science, technology and medicine with a special emphasis on European literature.

Key takeaways

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

Reference excerpt

PASCAL is a scientific bibliographic database, which is maintained by INIST (CNRS). PASCAL covers the core scientific literature in science, technology and medicine with a special emphasis on European literature. As of 2012, PASCAL maintains a database of more than 17 million records, 90% of which are author abstracts. Its coverage is from 1973 to present. Its source documents are composed of journal articles at 88% (3,085 international titles), proceedings at 9%, and dissertations, books, patents, and reports account combined for 3%.

Worked examples

Example 1 — a first encounter with PASCAL (database)

Start with the simplest possible case. Write down what PASCAL (database) 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 PASCAL (database) 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 PASCAL (database) 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 PASCAL (database)

In research: PASCAL (database) 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 PASCAL (database) 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: PASCAL (database) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bibliographic databases and indexes, Database stubs, French National Centre for Scientific Research, so understanding it makes those chapters shorter.
In everyday life: Look for PASCAL (database) 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.
