Study Notes
METHODS FOR ACCESSING FILES
- Sequential access organizes records in numerical order, making insertion difficult and requiring whole file rewrites for updates.
- Primary keys uniquely identify records (e.g., Social Security Numbers, account numbers) for data organization and retrieval.
- Sequential files are ideal for backup due to their infrequent updates, though they are time-consuming with high data redundancy.
LOGICAL DATABASE DESIGN
- Information in databases has two views: physical (storage specifics) and logical (user-oriented).
- There may be multiple logical views per user for effective organization and retrieval of information.
- Data models dictate how data is created, represented, organized, and maintained, with key components like data structure, operations, and integrity rules.
COMPONENTS OF DBMS
- Database Engine: Manages data storage, manipulation, and retrieval, converting user requests into physical data operations.
- Database Definition: Maintains the data dictionary and defines the database structure.
- Database Manipulation: Facilitates adding, deleting, modifying, and retrieving records using query languages like SQL.
- Application Generation: Handles tasks such as security, backup, recovery, and user permissions (CRUD).
- Data Administration: Manages database design, security, performance evaluation, and recovery procedures.
DATA MODELS
- Hierarchical Model: Records are arranged in a tree-like structure with nodes (records) connected by branches (relationships).
- Network Model: Similar to the hierarchical model but allows multiple parent-child relationships amongst records.
- Relational Model: Data is organized in two-dimensional tables. Rows represent records (tuples) and columns represent fields (attributes).
- Data Dictionary: Contains definitions such as data types, default values, and validation rules for fields.
- Normalization: Reduces data redundancy, ensuring related data is stored in tables across various normal forms (1NF to 5NF).
RECENT TRENDS IN DATABASE USE
- Data-Driven Websites: Interface with databases to retrieve and allow user data entry, improving information access and reducing maintenance.
- Data Warehousing: Collects data from multiple sources to support decision-making and business intelligence, characterized by aggregated, subject-oriented data categorized over time.
- Distributed Database Management System (DDBMS): Stores data across multiple servers, enhancing design reflection of organizational structure, performance, and security.
DATABASE MARKETING
- Utilizes customer databases for proactive marketing strategies aims to enhance profits, competitiveness, and long-term customer relationships through tasks like CLTV calculation and RFM analysis.
DATA VISUALIZATION TOOLS
- Tableau: Offers data visualization for BI, enables trend analysis.
- Power BI: A Microsoft tool for visualizing and integrating data from various sources, aiding in decision-making.
PRIVACY ISSUES
- Employers monitor social media for background checks, raising concerns about personal data collected by organizations across various sectors.
- Federal laws such as HIPAA, FACTA, COPPA, and GDPR regulate personal data collection, protection, and consent.
EMAIL AND DATA COLLECTION
- Spam refers to unsolicited bulk emails and raises concerns about privacy and the potential misuse of personal data online.
- Cookies are small files used to customize user experience but can be intrusive without consent.
- Companies should ensure secure data collection practices, specifying purposes, obtaining necessary consents, and implementing verification for data accuracy.
INTELLECTUAL PROPERTY
- Comprises industrial property (inventions, trademarks) and copyrighted material (literary and artistic works).
- Fair Use Doctrine permits limited use of copyrighted materials under specific circumstances.
- Trademark protections cover product identifiers, while patents safeguard innovative processes.
ETHICAL ISSUES IN INFORMATION TECHNOLOGY
- Increased ease of information collection raises risks of cybercrime and identity theft.
- To mitigate unethical practices, organizations should enforce ethical standards and codes of conduct among employees.### Cybersexual and Internet Compulsions
- The speed of Internet connections influences user behaviors and compulsions.
- Types of web compulsions include gambling, shopping, stock trading, along with cyber-relationships and online gaming.
- Information-seeking through the Internet is increasingly common, impacting workplace dynamics.
Health and Safety Concerns with Technology
- Distracted walking while using smartphones can lead to various injuries like sprains and fractures, or even fatalities.
- "Selfie deaths" occur when individuals take risks for photographs in hazardous situations.
- Common health issues associated with technology use include vision problems, musculoskeletal injuries, stress-related injuries, and reproductive challenges.
Overcoming Internet and Smartphone Addiction
- Acknowledgment of the addiction problem is the first step to recovery.
- Recommendations include limiting usage, actively engaging in social activities, and maintaining device-free times.
- Professional help may be necessary for severe cases of addiction.
Green Computing
- Focuses on creating a sustainable environment with minimal energy consumption throughout the lifecycle of computer devices.
- Involves cooperation from both private and public sectors for effective implementation of green practices.
- Strategies include designing energy-efficient devices, recycling materials, and minimizing business travel by using remote communication technologies.
Achieving Green Computing
- Design durable products with modular capabilities for easy upgrades.
- Optimize computing routines to be faster and energy-efficient.
- Utilize virtualization techniques to consolidate server usage.
- Promote remote work arrangements and encourage public transportation.
Database Knowledge Assessment
- Both internal and external data can be stored in a database.
- Random access file structures are ideal for quick processing of small record sets.
- The Network Model allows for multiple parent and child record relationships, differentiating it from the hierarchical model.
- An incorrect statement about Data Administration includes a failure to evaluate data performance.
Key Concepts in Data Management
- DDBMS setup approaches consist of fragmentation, replication, and migration.
- Data warehouses support decision-making applications and can handle large volumes of data.
- Benefits of data marts include faster access, improved response times, and simpler creation.
Big Data Eras and Data Regulation
- The 5Vs of big data are volume, variety, velocity, veracity, and value, emphasizing the multiple dimensions of data.
- Acceptable use policies govern the legal and ethical aspects of system usage.
- Internet neutrality ensures equal treatment of all data online, preventing discrimination by ISPs.
Information Technology Impacts
- Telecommuting enhances workforce flexibility, allowing employees to work from home.
- Information technology creates a digital divide, separating individuals by data access capabilities.
- Implementing sustainable practices is essential for minimizing environmental impact from technology use.
