Microsoft Azure and On-Premises Computing

Question: Explain what Microsoft Azure is and discuss how cloud computing on Azure differs from traditional on-premises computing.

Answer: Microsoft Azure is Microsoft’s cloud platform that provides services like virtual machines, storage, databases, networking, and AI. Compared to on-premises computing (where you buy, own, and maintain servers), Azure lets you rent resources on demand (pay-as-you-go), scale up or down quickly, deploy globally, and use many

Cloud Computing Fundamentals

Cloud computing is a technology that allows users to store, manage, and process data over the internet instead of using local computers or physical servers.

Key Features of Cloud Computing

  • Provides on-demand access to computing resources.
  • Reduces the need for expensive hardware.
  • Users pay only for what they use (pay-as-you-go).
  • Data can be accessed from anywhere with internet connectivity.

Types of Cloud Services

  • IaaS (Infrastructure as a Service): Virtual machines, storage.

Database Management Systems

  • DBMS Software Components

    A Database Management System (DBMS) contains five important software components. One of these is the: Data Definition Subsystem.

  • Primary and Foreign Keys

    Every primary key can also be used as a: Foreign Key (when referencing another table).

  • Storing Facts About Information (Metadata)

    If you needed to store facts about the information you were collecting, you would use a: Data Dictionary.

  • Unique Identification Field

Korn Shell Relational Expressions

In Korn shell (and other Bourne-like shells), relational expressions are typically evaluated inside the [[ ... ]] (conditional) construct or using the test (or [) command. The operators use mnemonics for numerical comparison.

1. Numerical Comparisons in Korn Shell

(a) c ≥ d

To check if the numerical value of variable c is greater than or equal to the numerical value of variable d:

[[ $c -ge $d ]]

The -ge operator stands for “greater than or equal to”.

(b) c < d

To

Hybrid Hash-Join Performance Optimization in Database Systems

Hybrid Hash-Join: Conceptual Explanation

Hybrid Hash-Join is an improved version of the standard Hash-Join algorithm that reduces disk I/O by using memory more efficiently during the join operation. It is particularly useful when:

  • The build relation is larger than memory.
  • Memory is still large enough to hold one or more partitions fully.

Why Use Hybrid Hash-Join?

In a normal Hash-Join:

  • All partitions of the build relation are written to disk first.
  • They are then read again for probing.

Hybrid Hash-Join
