Study Notes

Business Skill Priorities for 2027

  • Businesses prioritize skills like information management, data processing, and knowledge work in 2027.

Data, Information, Knowledge

  • Data: Raw facts and figures. (Operational significance)

  • Information: Data that has been processed and organized. (Operational significance)

  • Knowledge: Understanding of the relationships between information and associated actions. (Strategic significance)

  • The DIKAR and RAKID models illustrate the flow from data to knowledge and possible actions/results.

Knowledge Types

  • Knowledge workers: Employees whose main asset is knowledge (e.g., healthcare professionals, software engineers).
  • Expert systems: Computer systems that mimic human experts, often in areas like medicine.
  • Wisdom: Evaluated understanding, often involving ethical considerations.

Relational Databases

  • Relational databases store data in tables and allow connections between tables.
  • Relationships facilitate accessing data in various ways without reorganizing tables.
  • Database design should be structured, reliable, and consistent.

Database Design Principles

  • Data organization: Separate data into smaller logical parts (like unique identifiers and addresses) for better organization and sorting. Avoid derived fields (fields already in another table) to prevent data entry errors.
  • Descriptive field names: Use clear, concise, and consistent field names with no excessive abbreviations.
  • Unique field names: Assign unique primary keys to each record to identify them uniquely.
  • Unique records: Each record must be distinct; duplicated records should be avoided; using a primary key to ensure unique records
  • No calculated fields: Avoid calculating fields within the data table; calculate them in queries, forms, or reports after extracting the data, to prevent potential errors.

Data Types

  • Databases use different data types (integers, floats, characters, strings, booleans) to store various types of data with different storage requirements and operations.

Basic Database Operations

  • Create Tables: Define table structure and fields.
  • Data Entry: Add data, potentially manually, automatically, or importing from other sources.
  • Queries: Retrieve specific information from the database based on criteria.
  • Reports: Generate formatted documents from the database.

Database Options

  • Database software options range from simple (like Excel) to complex systems (like Oracle/SQL). Access is a commonly used relational database system.
  • Security is crucial; consult with security professionals for sensitive data.
  • Consider the number of users required and the level of complexity for your needs

Information Management Strategy

  • An information management strategy helps businesses and individuals operate more strategically, improve communication, and gain insights to make informed decisions.

Computer Hardware

  • CPU: Processes instructions using the ALU (arithmetic logic unit) and CU (control unit).
  • Registers: Store intermediate results.
  • Bus: Connects components within a computer or between computers.
  • Memory: Primary memory (RAM, registers, cache, ROM); Secondary memory (hard disks, CDs, DVDs, USB sticks).
  • Storage capacity: Units of measurement for storage (bytes, kilobytes, megabytes, gigabytes, terabytes, petabytes, exabytes...). Data storage devices (hard drives, optical disks, flash drives).
  • Peripherals: Expansion cards (graphics, sound, network).

Embedded Systems

  • Embedded systems are computer systems designed for specific tasks.
  • Mobile hardware, like smartphones and tablets, is optimized for portability and performance.

Mobile Hardware

  • Smartphones, tablets, laptops, and smartwatches are common types of mobile devices; these devices are designed for portability.
