Q1. Differentiate between DDL and DML Languages with example. [5 Marks]
Answer:
DDL (Data Definition Language) is used to define, create and modify the structure of database objects such as tables,
databases and schemas. It mainly deals with the structure of the database.
Commands: CREATE, ALTER, DROP, TRUNCATE.
Example:
CREATE TABLE Student(Roll_No INT, Name VARCHAR(20), Age INT);
DML (Data Manipulation Language) is used to insert, modify, delete and retrieve data stored in database tables. It

What metrics on the QuickBooks Advanced dashboard from day one?
▸ Tier 1 — Funnel health: lead volume by source, MQL count, sync rate, routing accuracy
▸ Tier 2 — Velocity: stage-to-stage speed, conversion at each handoff, time-to-first-touch (most important for this buyer)
▸ Tier 3 — Outcomes: pipeline, opps, win rate, revenue by source
▸ Hidden metric: undispositioned lead % — invisible in reporting, biggest leakage
Q8 · PRIORITIZATION
How do
...True.If a class contains an abstract method, the class must be declared abstract.
True.A class can implement multiple interfaces in Java.
True. With a parent reference pointing to a child object, an overridden instance method is selected based on the actual object at runtime.
False. A subclass cannot reduce the visibility of an overridden method.
True.A final method cannot be overridden by a subclass.
Both interfaces and abstract classes support abstraction. Both can define abstract methods that
False.An abstract class cannot be instantiated directly. You cannot create an object of an abstract class using new. You must create an object of a concrete subclass.
False.Java does not allow a class to extend more than one class. However, a class can implement multiple interfaces.
False.Method overloading means having the same method name but different parameter lists. A different return type alone is not enough.
True.The reference type determines which methods are available at compile time. The

What is an atom?
The smallest basic unit of matter that makes up every element and chemical substance.
What are subatomic particles? Name the three main subatomic particles.
Particles smaller than an atom that form its internal structure. The three main particles are electrons, protons, and neutrons.
Define an electron and state its relative charge and mass.
A negatively charged subatomic particle found outside the nucleus. Its relative charge is...

Ans Graphical Demonstration: Increase in Investment and Proportionate Increase in Income
In the simple Keynesian model, national income is determined by aggregate expenditure. Assume a closed
economy with no government and no foreign trade.
Equilibrium condition: Y = C + I.
Let C = a + bY. When autonomous investment rises by ΔI, aggregate expenditure rises.
