What is an Application Architecture?

1 pts

volume_mute

Application architectures encapsulate the principal characteristics of a class of systems. Which of the following best explains why application architectures exist?

Because application architectures eliminate the need for requirements engineering

Because every software system is unique and requires a completely custom architecture

Because businesses and applications within the same sector have much in common, leading to software architectures that describe the structure and organisation of particular types of software system

Because hardware vendors impose architectural standards that all applications must follow

Starting point for architectural design

Assessing components for reuse

Design checklist

Organising work of the development team

Vocabulary for talking about application types

Description

Base your initial design on a generic architecture, specialising it for the specific system being developed

Compare your developed architectural design with the generic architecture to check consistency

The architecture identifies stable structural features that can be developed in parallel by different team members

Compare existing components against the generic structure to see whether comparable components exist for reuse

Use concepts from the generic architecture to discuss and compare applications of the same type

Transaction Processing Systems - Definition

1 pts

volume_mute

Which of the following best describes a Transaction Processing (TP) system?

A system that compiles source code into executable machine code

A system that processes batches of data files without any user interaction

A system that monitors network traffic and filters packets in real-time

A database-centred application that processes user requests for information and updates a database, where a transaction is a sequence of operations treated as a single atomic unit

ATM Transaction Example

1 pts

volume_mute

Consider a customer withdrawing cash from a bank ATM. Which statement correctly explains why this constitutes a database transaction?

Because any cash withdrawal automatically creates a new account record

Because ATM operations always run in parallel with other customer transactions

Because it involves getting customer account details, checking the balance, modifying the balance by the amount withdrawn, and commanding the ATM to deliver cash - all of which must be completed as a unit before the database is changed

Because the ATM is physically connected to the bank's computer

Transaction Management / Database

User Interface

Function

Handles all interaction with the user; implemented using a web browser in modern systems

Manages user login, role checking, form and menu management, and data validation

Implements application-specific logic for accessing and updating the database; includes security, data import/export, and report generation

Provides persistent data storage, transaction management, and data integrity using a commercial DBMS

Language Processing Systems - Purpose

1 pts

volume_mute

Which of the following correctly describes what a language processing system does?

It translates a natural or artificial language into another representation, and for programming languages may also execute the resulting code

It manages communication between distributed software components over a network

It manages the persistence of application state between user sessions

It checks for grammatical errors in user-facing text interfaces

Compiler Architecture Components

1 pts

A general-purpose programming language compiler includes six key components. Match each component to its function.

To complete the line match

Click on an item in the first group
Click on the match in the second group

To delete a match, double click on a line

Component

Lexical analyzer

Syntax analyzer

Symbol table

Semantic analyzer

Syntax tree

Code generator

Function

Takes input language tokens and converts them to an internal form

Holds information about the names of entities (variables, class names, object names, etc.) used in the text being translated

Checks the syntax of the language being translated using a defined grammar and builds a syntax tree

An internal structure representing the program being compiled

Uses information from the syntax tree and the symbol table to check the semantic correctness of the input language text

Walks the syntax tree and generates abstract machine code

Two Architectures for a Compiler

1 pts

volume_mute

A compiler can be organized using two alternative architectural patterns. Which of the following correctly describes when each is preferable?

Pipe and Filter is effective in batch environments where programs are compiled without user interaction; Repository is better when the compiler is integrated with other tools like structured editors, debuggers, or prettyprinters, where changes must be reflected immediately across components

Repository is always preferred because it is simpler to implement than Pipe and Filter

Pipe and Filter for all compilers; Repository never used for compilers

Pipe and Filter is used only for natural language processing; Repository is used only for machine code generation

ERP Systems and Application Reuse

1 pts

volume_mute

Enterprise Resource Planning (ERP) systems exemplify a particular form of application architecture reuse. Which of the following best describes this form of reuse?

ERP systems reuse individual software components but always require a completely new architecture

ERP systems are custom-built from scratch for each organisation and share no common code

ERP systems reuse the user interface only, with all business logic re-implemented for each organisation

A generic system is configured and adapted to create a specific business application, allowing application reuse without re-implementation

Language Processing System Architecture

1 pts

In a basic language processing system architecture, a source language program flows through two main stages before producing results. Drag the correct term into each placeholder.

Source language instructions are fed into a (1), which checks syntax and semantics and generates abstract machine instructions. These instructions are then fed into an (2), which fetches and executes them using data from the environment to produce results.
