• Auto-generates an index/TOC based on heading styles in the document
• Helps readers navigate large documents quickly
• Updates automatically when content changes
• Gives a professional look to formal documents and reports

• Groups data by a specific column and inserts subtotals automatically
• Performs calculations like Sum, Average, Count on grouped data
• Simplifies analysis of large datasets
• Allows collapsing/expanding groups for better readability

• All sheets/ranges to be consolidated must have the same data structure (same column/row layout)
• Correct cell references and ranges must be defined before consolidation
• Data should be in a proper tabular format without blank rows

Data refers to raw, unprocessed facts and figures that have no meaning on their own.

Information is processed, organised data that is meaningful and useful.

Example: "Yogesh, 100" is data — it cannot be understood alone. But "Yogesh has scored 100 marks in IT subject" is information — it is meaningful and conveys a clear message.

Causes:

• Electric shock due to exposed/damaged wires
• Short circuit due to overloaded circuits or faulty equipment

Prevention: Ensure proper insulation of all wires and always handle electrical equipment with dry hands.

• Stay calm: Do not panic; a clear mind helps in taking the right action
• Inform authorities: Alert supervisor or emergency services immediately
• Use emergency exits: Evacuate the area using marked exits, do not use lifts
• Provide first aid: Administer basic first aid while waiting for professional help

(a) Four ways to insert an image:

• Copy and Paste from file/clipboard
• Drag and Drop from file manager into document
• Insert → Image → From File (using menu)
• Scan directly using Insert → Image → Scan

(b) Wrap Off vs Wrap Through:

• Wrap Off: Text does not flow around the image at all. The image sits on its own line and text appears above or below it.
• Wrap Through: Text flows over the image, passing through it. The image appears behind the text, useful for watermarks or creative layouts.

• Open the original spreadsheet Bill.ods in LibreOffice Calc
• Go to Edit → Track Changes → Compare Document
• Select the reviewed file Rev_Bill.ods to compare
• Calc highlights the differences between the two files automatically
• Review each modification carefully — changed cells are marked in different colours
• Accept or reject changes as needed and save the corrected version separately

(a) Reports are used to display formatted database output that is easy to read, suitable for printing and sharing. They summarise data from tables/queries in a professional format.

(b) Yes. Reports can be generated from multiple tables by creating a query that joins those tables first, and then basing the report on that query.

(c) A dynamic report automatically updates its data whenever the underlying database changes. Unlike a static report (which is a fixed snapshot), a dynamic report always reflects the most current data.

(d) Steps to insert date and time in report header:
Step 1: Click inside the Page Header area to activate it.
Step 2: Click Insert → Field → Date/Time

(a) Health hazards from high contrast: Eye strain (tired, sore eyes) and Headaches due to continuous squinting or refocusing.

(b) Position the monitor so that bright light sources (windows, lamps) are to the side, not directly behind the screen. Use blinds or curtains to reduce glare.

(c) Poor posture can cause neck pain, back pain, shoulder strain, and long-term musculoskeletal disorders. It may also lead to poor circulation and fatigue.

(d) Take regular short breaks from work (every 30–45 minutes), practice deep breathing, or engage in light stretching exercises at the desk.

(a) Columns where duplicate values are allowed: ItemType, Quantity, Price, Supplier, Size (any two acceptable — these are not primary key or unique columns).

(b) No. ItemID is the Primary Key of the Gadgets table. Primary keys must be unique — no two records can have the same ItemID. Entering I001 again will result in an error.

(c) Yes. Photos can be stored using the Binary (BLOB — Binary Large Object) data type, which can store large binary data like images.

(d) Referential Integrity: The ItemID column in the Bill table is a foreign key referencing ItemID in the Gadgets table. Referential integrity ensures that every ItemID value in the Bill table must exist in the Gadgets table. You cannot add a billing record for an item that doesn't exist in Gadgets.
