Key Topics

  • Introduction to Transaction Processing
    TR-1

    This topic introduces the concept of transaction processing, highlighting the differences between single user and multi-user systems, read/write operations, and the need for concurrency control to avoid problems such as lost update, temporary update, incorrect summary, and unrepeatable read.

  • Transaction and System Concepts
    TR-2

    This topic covers the fundamental concepts of transactions, including transaction states, system log, and commit point of transaction.

  • Desirable Properties of Transactions
    TR-3

    This topic discusses the desirable properties of transactions, namely atomicity, consistency, isolation, and durability (ACID).

  • Schedules and Concurrency Control
    TR-4

    This topic explores schedules, conflicting operations, and characterizing schedules based on recoverability and serializability, including serial, non-serial, and conflict serializable schedules.

Key Topics

  • Multipath Propagation Environment
    WI-1

    This topic covers the concept of multipath propagation in wireless channels, where a signal reaches the receiver through multiple paths. It explores the effects of multipath on signal quality and reliability.

  • LTI Channel Model
    WI-2

    This topic introduces the Linear Time-Invariant (LTI) channel model, which is used to describe the behavior of wireless channels. It explains the assumptions and limitations of the LTI model.

  • Channel Correlation Function
    WI-3
