ORDATA

ORDATA 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 ORDATA rather than just read about it. In short: ORDATA is a United States government database of landmines and other unexploded ordnance, developed to assist humanitarian demining work. The original version of ORDATA released in 1997 was CD-ROM based, and incorporated material from the earlier Minefacts program.

Key takeaways

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

Reference excerpt

ORDATA is a United States government database of landmines and other unexploded ordnance, developed to assist humanitarian demining work. The original version of ORDATA released in 1997 was CD-ROM based, and incorporated material from the earlier Minefacts program. ORDATA 2.0 was distributed on a CD-ROM and on the Internet. The database is hosted on the Center for International Stabilization and Recovery website, a part of James Madison University. In 2014-15 the interface underwent a revision and the data partially updated. The new site is known as the Collaborative ORDnance Data Repository (CORD) and is available online. An offline version is in development.

Worked examples

Example 1 — a first encounter with ORDATA

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

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

Why does ORDATA matter?

Because it connects several 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 ORDATA?

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.
