System Development Lifecycle (SDLC)

A structured approach to developing information systems. It involves planning, analysis, design, implementation, testing, deployment, and maintenance.

Project Management

A set of tasks and activities performed by a team to manage a specific project. It includes planning, organizing, and controlling resources to complete the project on time and within budget.

1st Gen Programming Language

First generation programming languages use machine language, which is a low-level language consisting of binary code. This code directly instructs the computer's hardware, but it's complex for humans to understand and write.

2nd Gen Programming Language

Second generation programming languages use assembly language, which is a step up from machine language. It uses mnemonics (short codes) to represent instructions, making it easier for humans to read and write.

Business Informatics (BI) Introduction

  • The core objective of this course is to provide students with key BI concepts, facilitating communication between business leaders and IT professionals.
  • Common project failures stem from a lack of agreement, misinterpretations, and unclear explanations.
  • An effective project description is crucial for realizing a positive return on a high investment.

Basic Concepts in Business Informatics

  • Hardware: Tangible components and equipment.

    • Input: Devices for inputting data (keyboard, audio, video).
    • Output: Devices for displaying data (screen, audio).
    • Memory: Internal and external storage.

  • Software: Intangible instructions executed by hardware.

    • Written in human-readable language, then translated into binary code.
    • Software is composed of modules (sub-groups).
    • Easily reusable, less complex, easier to debug, supports parallel development.

  • Database: Organized collection of data stored in the computer.

    • Includes relational databases enabling connections between different databases.

  • Network: Enables communication and data exchange between multiple computers and servers using protocols.

    • Protocols outline precise steps for processing operations.

  • Servers: Specialized computers solely for processing and storing data via networks.

    • Requires no visual interface as communication occurs through the network.

  • Internet: Large interconnected network; high penetration in developed economies.

  • Computer Architecture: Historical evolution of the fundamental organization of computer systems.

    • Mainframe: Large, centralized early computers; still used in some contexts.
    • PC and Client-Server: Individual PCs function semi-independently but interact with client/server networks.
    • Browser-Cloud: Current model where devices use cloud-based services via internet connections.

  • Processes: Sequential actions to generate a service/product. -Business processes are sequences of steps to generate a product or service within an organization.

    • Informational systems include hardware, software, support processes, and personnel.

Algorithms

  • Algorithms are methods for solving problems in a systematic manner, starting from a given situation and progressing towards a defined goal within a timeframe.
  • Algorithms can be visualized via flowcharts, pseudocode, or Nassi-Schneidermann diagrams.
  • Basic flowchart figures: operations, input/output, decisions (branching) and begin/end.

Control Statements/Iterations

  • While loop: Repeatedly executes a block of code as long as a condition remains true.
  • For loop: Executes a block of code repeatedly for each item in a sequence.

Programming

  • Programming involves translating problems into instructions the computer understands.
  • Generations of programming languages:
    • First generation: Raw machine code (0s and 1s).
    • Second generation: Assembler language using mnemonics.
    • Third generation: Higher-level languages like Ada, Basic, Java, Python.

Data Types

  • Single predefined types:
    • Integer (e.g., 10)
    • Float (real number, e.g., 3.14)
    • Character (e.g., 'A')
    • Boolean (e.g., True/False)
  • Self-built single types:
    • Enumerated (list of values)
  • Self-built multiple types:
    • Arrays (fixed-size, homogeneous)
    • Aggregated (variable count and type)

Control Structures

  • If Statements: Conditional execution based on a condition being met.

Iterations (Loops)

  • While loops: Repeated execution as long as conditions are true.
  • For loops: Repetition over sequence items or specified ranges.

Data Mining

  • Using data to gain business insights.
  • 'Big data' processing tools are helpful.

Security and Privacy

  • Safeguarding information is vital in today's business world.
  • Protecting critical systems, preventing data leaks, and enforcing strong security procedures are paramount.
  • Measures include software updates, antivirus applications, firewalls, data backups, and encryption.

Business Context

  • Modern businesses require robust IT systems for effective communication, efficiency, and alignment with business goals.
  • Proper IT implementation is crucial for achieving high Return on Investment (ROI).
  • Inadequate planning and unclear specifications are major contributors to project failures.

Enterprise Applications

  • System development lifecycles are necessary to implement IT systems; they've specific phases.
  • The planning phase must cover project scope, alignment with business goals, cost and benefits analysis, feasibility studies, risks, resources, and timelines.

Supply Chain Management

  • Includes the transportation and storage of raw materials, work-in-process goods, and finished products.
  • Essential for product and service delivery from origin to final customer.

Customer Relationship Management (CRM)

  • Aimed at improving business interactions with customers.
  • CRM systems allow for data analysis on past customer interactions to improve customer relationships.
  • Three main CRM types: customer-facing, customer-touching, and customer-centric intelligence.
