Study Notes

Unit One: Information Systems and Their Application

Objectives: Explain ethical and legal issues in information systems, environmental, health, and social issues in information systems, intellectual property rights, digital identity management, and the role of digital technologies in citizenship.
1.1. Impacts of Information Systems: Ethics plays a vital role in decision-making in fields like healthcare, education, and business.
1.1.1. Ethical and Legal Issues: Standardized ethical guidelines are important in information systems as technology advances.
- Privacy Concerns: Digitization of personal data raises privacy issues, with unauthorized access posing ethical and legal risks.
- Digital Ownership: The rights individuals have over their digital content and the issues of copying and sharing content online without permission are unethical.
- Information Gathering Practices: Ethical questions arise around the extent and purpose of data collection without transparent consent processes.
- Information Security and Liability: Organizations face rising risks of security breaches which can cause identity theft and other malicious activities.
1.1.3. Environmental Issues: Technology advances can impact the environment with consumption of resources and leading to ecological damages. E-waste is a problem with hazardous materials that contaminate soil and water. Minimizing harm through responsible disposal is crucial.
1.1.4. Health Issues: Health information systems are essential to health care delivery, generating data to improve care, empowering patients, and addressing challenges of unmanaged use of information systems.
- Health problems from excessive technology use: Can result in sleep disorders, stress, productivity loss, musculoskeletal issues, and vision problems/obesity.

Unit Two: Emerging Technology

Objectives: Describe the meaning and use of Big Data, explain cloud computing and fog computing, apply cloud computing services, explain the Internet of Things (IoT) and its applications.
2.1. Introduction to Big Data: Big data refers to massive and complex data sets challenging to process traditionally. This explosion results from increased computing power, the internet, and technology capturing physical world information.
- Characteristics of Big Data (5 Vs.): Volume, variety, velocity, veracity, and value.
- Benefits of Big Data: Customer acquisition/retention by analyzing consumer data, targeted marketing, and improved customer satisfaction. Also used in targeted advertising, product development, price optimization, and risk management to make more informed decisions.
2.2. Cloud Computing: The practice of storing/accessing data and computing services via the Internet.
- On-Demand Services: Computing services (servers, data storage, networking, databases) are accessible as needed.
- Accessibility: Multiple users access data from one data center.
- Real-World Examples: Gmail, Google Maps, Amazon, Netflix, PayPal, Spotify, and Adobe Creative Cloud.
- Benefits: Accessibility, mobility, data backup, flexibility, improved efficiency.
- Limitations: Server downtime, security issues, data ownership concerns, inflexibility, lack of support, cost.
2.2.3. Types of Cloud Computing: Public, private, community, and hybrid are common types.
2.3. Fog Computing: An extension of cloud computing with 'fog nodes' closer to data sources, like devices. This allows for higher processing and storage capabilities, reduces latency and enhances user experience. This is particularly relevant to IoT.
2.4. Internet of Things (IoT): A network of interconnected physical objects (things) collecting and exchanging data.
- Functionality: Remote device control, reduces human effort, and enhances user experience.
- Examples: Animal tracking devices, diabetes monitors, air conditioning sensors, and wearable technology.

Unit Three: Database Management System (DBMS)

Objectives: Describe relational database management systems, explain fields and records, apply SQL data definition language (DDL) to create tables, differentiate between DDL, data manipulation language (DML), and data query language (DQL), apply SQL DML to manipulate records, and apply SQL DQL to query records.
3.1. Overview of Relational Database Management Systems (RDBMS): Software for creating, maintaining, and managing databases using the relational model to organize data in structured tables.
- Structure of Data (Tables): Composed of rows (records/tuples) and columns (attributes/fields), each defining characteristics of an entity.
3.2. Database Manipulation Using SQL: SQL (Structured Query Language). Includes Data Definition Language (DDL), Data Manipulation Language (DML), and Data Query Language (DQL).
- DDL: Used to define the database structure, with commands like CREATE (for creating tables), ALTER (changing table structure), and DROP (to delete tables).
- DML: Used to manipulate the data within the tables, such as INSERT (to add new data) UPDATE (to modify existing data), and DELETE (to remove data).
- DQL: Used to query data from tables, such as SELECT (to retrieve data) to meet specific criteria (e.g., filtering records).
Query Optimization: How to retrieve required data efficiently. Filtering records (WHERE clause), sorting results (ORDER BY clause), and joining data (querying multiple tables) are all factors in optimization.
