Q.Name the four main objects of a LibreOffice Base database and state the purpose of each in one line.

This question checks that you know the building blocks of a Base database and what each one is for.

A LibreOffice Base database is built from four main kinds of object, each with its own purpose:

1. Table — where the actual data is stored, arranged in rows (records) and columns (fields). Everything else is built on top of tables.
2. Query — used to retrieve exactly the records you want from one or more tables, and optionally to sort them or perform calculations.
3. Form — a friendly on-screen window for entering and editing data one record at a time, using labelled boxes instead of a wide grid.
4. Report — a neatly formatted, printable summary of the data, meant for reading and sharing rather than editing. Together they act as a team: tables hold the data, queries pick out what is needed, forms make entering that data easy, and reports present it clearly.
   ✓Final answer

   (i) Table — stores data in rows and columns; (ii) Query — retrieves exactly the required records; (iii) Form — an easy window to enter and edit data; (iv) Report — a formatted, printable summary of the data.

Keep the roles distinct: a query only retrieves data (it stores none of its own), while a table stores it. Do not mix up a form (for entering/editing data) with a report (for presenting/printing data).
