Study Notes
Understanding Computer Architecture
- Computers process information using software and hardware.
- Software is a set of instructions for a computer, analogous to a to-do list.
- Hardware encompasses the physical components of a computer (e.g., CPU, memory, hard drive).
- Computers use binary code (zeros and ones) to represent electrical states, forming the basis of their language.
The CPU as a Central Hub
- The CPU (Central Processing Unit) acts like a train station, directing electrical signals (data) to different parts of the computer.
- The CPU can manipulate large amounts of zeros and ones quickly, allowing it to interact with humans.
- Bits are individual electrical states (zeros or ones), while bytes are groups of 8 bits.
- The CPU uses a computer dictionary (like Unicode or ASCII) to translate binary code into human-readable characters.
Programming Languages and Communication
- Programming languages allow programmers to write instructions for the computer in a more understandable format than binary code.
- The keyboard translates keystrokes into electrical impulses, which are then processed by the CPU and sent to specific components.
The Motherboard and Its City
- The motherboard is like a city, with the CPU as the central station and town hall.
- RAM (Random Access Memory) is the parking garages, holding information temporarily.
- HDDs (Hard Disk Drives) are the warehouse district, storing information long-term.
- GPU (Graphics Processing Unit) and sound cards serve as factories, converting raw data into visuals and sound.
- Integrated circuits act as roads, connecting different components.
The Flow of Data in an EIS
- Data flows through the EIS through a lifecycle of collection, processing, storage, usage, modification, and distribution.
- Data entry originates from external sources.
- Data processing prepares data for specific organizational purposes.
- Data storage involves storing processed data in databases or other storage systems.
- Data usage utilizes stored data for various purposes, such as decision-making, planning, and marketing.
- Data modification updates data based on new information (e.g., customer purchases).
- Data distribution shares relevant data with external stakeholders (e.g., customers, suppliers).
Data Categories in an EIS
- Data in an EIS can be categorized into various types, such as customer data, product data, financial data, employee data, etc.
Challenges of Data Management
- Data quality ensures accurate, complete, and up-to-date data.
- Data security protects sensitive data from unauthorized access.
- Data privacy complies with regulations and protects personal information.
- Data volume involves managing ever-increasing quantities of data for meaningful insights.
Common Computer Data Types
- Boolean data represents true/false values (1/0).
- Integers represent whole numbers (e.g., 1, 5, -10).
- Floats represent numbers with decimals (e.g., 3.14, -2.5).
- Date/time data represents points in time.
- Strings are sequences of characters (e.g., "Hello World").
- Images are visual representations stored as data.
- Audio data represents sounds as digital signals.
- Video data combines images and audio for moving pictures.
- Objects are complex data structures representing real-world entities.
Typical Data Collected by Organizations
- The types of data collected by organizations are highly varied and depend on specific business processes.
- Common examples include customer demographics, product inventory, financial transactions, and employee records.
Introduction to Databases
- Data needs to be stored permanently to avoid data loss when a device shuts down.
- Relational databases are similar to a central refrigerator, storing data independently and accessible to all users.
- Relational databases store structured data, like spreadsheets.
- Spreadsheets use tables, columns, and rows to organize data.
Relational Databases
- Tables: Each table represents a single record of interconnected data.
- Rows: Each row is a complete record for an individual item.
- Columns: Each column represents a specific category of information within a table.
- Primary Key: Helps uniquely identify each row even if other data is identical.
- Database Management Systems (DBMS): Software used for accessing, modifying, and deleting data in a relational database.
- SQL (Structured Query Language): A programming language used to interact with relational databases.
Non-Relational Databases (NoSQL)
- Suitable for handling large, unstructured data.
- Data doesn't need to be predefined into tables like in relational databases.
- Data is typically stored across multiple servers, known as "sharding".
- Advantages: Scalability, speed, efficiency, and security.
Data Warehouses & Data Lakes
- Data Warehouses: Databases focusing on analyzing large amounts of historical data to identify patterns and trends.
- Advantages: Performance, scalability, integration, and quality.
- Data Lakes: Collect data from various sources, process raw unstructured data, and use AI for machine learning purposes.
- Different from data warehouses: Data lakes focus on "experimental learning" rather than solely business intelligence.
EIS Component: Software
- Software is a set of instructions, data, or programs that operate computers and execute specific tasks.
- Software is intangible, unlike hardware.
- Software tells hardware "WHAT" to do, "HOW" to do it, and "WHEN" to do it.
- Software is divided into System Software and Application Software.
- System Software manages and supports computer functions.
- Application Software interacts directly with users to perform specific tasks.
EIS Component: Data
- Data is a collection of facts, figures, and information.
- Interconnected devices are constantly collecting, analyzing, and sharing data.
- Data becomes valuable when it drives successful business decisions and operations.
Data Lifecycle in an EIS
- Data Entry: Data enters from outside sources through active collection (surveys, website analytics) or passive reception (customer orders, supplier invoices).
- Data Processing: Data is filtered and processed for organizational purposes, including cleaning, formatting, and combining data.
- Data Storage: Processed data is stored in databases or other storage systems.
- Data Usage: Stored data is used for various purposes, such as strategy formulation, production planning, and sales forecasting.
- Data Modification: Used data is often modified or updated, such as updating customer information after a purchase.
- Modified Data Storage: Modified data is stored back in the system, creating a continuous cycle.
- Data Distribution: Data is distributed to external stakeholders, such as customers, suppliers, or government agencies.
Challenges Of Data Management
- Data Quality: Ensuring data accuracy, completeness, and up-to-dateness.
- Data Security: Protecting sensitive data from unauthorized access.
- Data Privacy: Complying with regulations like GDPR and assuming Corporate Digital Responsibility.
- Data Volume: Managing ever-growing data volumes to derive useful insights.
Relational Databases
- Similar to spreadsheets, using rows and columns to represent records and types of information.
- Rows: Represent a single record or instance of interconnected data.
- Columns: Represent a specific type of information to be stored.
- Pre-determined columns can result in empty fields in records, especially with large datasets.
NoSQL Databases
- Flexible data storage without pre-defined structures, allowing for the addition of various data types.
- Data stored on multiple servers, decentralized across locations.
- Advantages of NoSQL: scalability, speed, cost-efficiency, and security.
Business Intelligence (BI)
- Uses software to analyze large volumes of raw historical data to identify patterns and trends.
- Shares insights and recommendations with managers for data-based strategy development.
Use Cases For Databases
- Relational Databases: Preferred for storing simple data, such as employee records, customer data, and inventory.
- NoSQL Databases: A necessary option for organizations dealing with Big Data or Internet of Things (IoT) data.
