Overview

[Audio] How Cloud Technology Works Cloud technology enables the delivery of computing services such as storage, servers, databases, networking, and software over the internet. It eliminates the need for physical infrastructure by allowing users to access resources on demand, paying only for what they use. This is achieved through a combination of virtualization, resource pooling, and scalable architectures. Cloud computing operates on a front end and back end architecture. The front end includes the user interface, which can be accessed via web browsers or applications. The back end consists of servers, storage systems, and databases that process and store data. These components are connected through a network, typically the internet, enabling seamless communication and data transfer. Virtualization is a key enabler of cloud technology. It allows multiple virtual machines to run on a single physical server, optimizing resource utilization. This ion ensures that users can scale resources up or down based on demand without worrying about the underlying hardware. Cloud services are categorized into three primary models: 1. Infrastructure as a Service (IaaS): Provides virtualized computing resources like servers and storage. Examples include AWS EC2 and Google Compute Engine. 2. Platform as a Service (PaaS): Offers a platform for developers to build, deploy, and manage applications without managing the underlying infrastructure. Examples include Google App Engine and Microsoft Azure. 3. Software as a Service (SaaS): Delivers software applications over the internet, accessible via a browser. Examples include Dropbox and Microsoft Office 365. Cloud deployment models include public clouds (shared resources), private clouds (dedicated to a single organization), hybrid clouds (a mix of public and private), and community clouds (shared among organizations with similar needs). Key benefits of cloud technology include scalability, allowing businesses to adjust resources dynamically; cost effectiveness, as users pay only for what they use; accessibility, enabling remote work; and security, with robust measures to protect data. In summary, cloud technology revolutionizes (I-T ) operations by providing flexible, scalable, and cost efficient solutions, making it indispensable for modern organizations. What is AWS? Amazon Web Services (A-W-S--) is the biggest cloud computing platform of all three. It offers computer resources and services that can construct applications in minutes at pay as you go prices.

[Audio] Basic Database Concepts A database system is a computer based solution designed for efficient record keeping and information management. It stores, organizes, and manages data to support decision making within an organization. A database is essentially a structured collection of interrelated data that represents information about a particular enterprise. Maintains data in a single, organized repository for multiple applications. Stores data separately from the programs that access it, allowing flexibility and scalability. Uses a generic and regulated approach to add, modify, and retrieve data securely. Organizes data in a way that supports easy integration with future applications and evolving business needs. Purpose of Database 1. Centralized Data Repository A database serves as a unified collection of data designed to support multiple applications within an organization. It acts as a single source of truth for storing, retrieving, and modifying information critical to operations and decision making. 2. Supports Continuous Operations Enables both ongoing data updates and quick access for tasks like control, monitoring, and planning. Users can query the database to gain insights or make informed business decisions. 3. Improves Over File Processing Systems Traditional file systems store data in separate files and require different programs for each function, leading to inefficiency and errors. 4. Solves Key Limitations of File Systems Databases address major challenges such as: o Data redundancy: Eliminates duplicate storage across files. o Data inconsistency: Ensures uniform and reliable data across applications. o Poor adaptability: Provides flexibility to evolve with business needs. o Lack of standardization: Enforces consistent formats and access rules. o Security gaps: Centralized control enhances data protection. Juniper Business Use Only.

[Audio] o Incorrect or outdated data: Maintains data integrity through validation and constraints. 5. Outcome: A Database Management System (D-B-M-S-) provides centralized control, accuracy, and efficiency, enabling seamless data management across the organization. Database Abstraction The major purpose of a database is to provide users with only the information they need, without exposing unnecessary details. The system hides the complexity of data storage and maintenance, enabling users to interact with data easily and securely. This is achieved through multiple levels of ion, each defining how data is viewed or managed within the system Levels of Database Abstraction The different levels of the database are implemented through three layers: 1. Internal Level (Physical Level) The lowest level of ion, closest to physical storage. Describes how data is actually stored on hardware (for example, files, indexes, and access paths). Focuses on data structures and storage efficiency. 2. Conceptual Level (Logical Level) Represents what data is stored in the database and the relationships among that data. Defines the database structure in logical terms such as tables, attributes, and constraints. Independent of physical storage users at this level are not concerned with implementation details. 3. External Level (View Level) The highest level of ion, closest to the end users. Defines how data is viewed by individual users or applications. Allows different users to see customized views of the same database, depending on their needs and permissions. Juniper Business Use Only.

[Audio] Data Abstraction Since databases operate across three levels of ion, changes at one level should not directly affect the others. This separation enables data independence, meaning: o Physical data independence: Changes in storage structure do not affect the logical schema. o Logical data independence: Changes in logical schema do not affect external views. As databases evolve and expand, this independence prevents the need for complete redesign or reimplementation, ensuring scalability and flexibility over time. Concept of Database To store and manage data efficiently, it’s important to understand several key concepts that define how a database is structured and operated: 1. Database Schema A blueprint or structural design of the database. Defines how data is organized including tables, columns, data types, constraints, and relationships. Acts as the foundation for how information is stored and accessed. 2. Data Constraints Rules that define what type of data can be stored in each column of a table. Juniper Business Use Only.

[Audio] Ensure data accuracy, validity, and consistency. Common constraints include PRIMARY KEY, ForEIGN KEY, unique, Not Null, and CHECK. Defined during table creation or modification. 3. Data Dictionary (Metadata) Also known as “data about data.” Stores details about database structure such as schema definitions, constraints, and table properties. Maintained automatically by the D-B-M-S for system reference and management. 4. Database Instance Represents the complete operational environment of a database. Includes memory structures and background processes that manage access to physical data files. Ensures that data is efficiently read, written, and maintained during runtime. 5. Query A request for data retrieval or manipulation using a query language such as SQL. Enables users to fetch, insert, update, or delete data as needed. Queries are the primary interface between users and the database. 6. Data Manipulation Refers to operations that modify data within the database. Includes Insertion, Deletion, and Updation of records. Performed through D-M-L (Data Manipulation Language) commands in SQL. 7. Data Engine The core component responsible for processing and executing database queries. Handles tasks such as query optimization, transaction management, and data retrieval. Ensures efficient performance and integrity of all database operations. Juniper Business Use Only.

[Audio] Normalization Normalization is the process of organizing a database to minimize data redundancy and dependency by dividing large, complex tables into smaller, well structured ones. Purpose: The goal of normalization is to create an efficient, consistent, and scalable database that is easy to update, manage, and maintain over time. Key Benefits: o Reduces data duplication and inconsistency. o Simplifies data modification and maintenance. o Ensures logical data organization and clarity of relationships. o Prevents update, insertion, and deletion anomalies. Normalization Rules: The process follows a series of normal forms each with specific rules to improve database structure: o First Normal Form (1NF): Eliminates repeating groups and ensures each field holds only atomic values. o Second Normal Form (2NF): Removes partial dependencies all non key attributes depend on the whole primary key. o Third Normal Form (3NF): Eliminates transitive dependencies between non key attributes. o Boyce Codd Normal Form (B-C-N-F-): Strengthens 3NF by ensuring every determinant is a candidate key. Advantages of Database A database system offers several key benefits that address the limitations of traditional file based systems and enhance overall data management efficiency: Reduces Data Redundancy Minimizes duplication of data by storing it centrally, ensuring that each piece of information exists only once across the system. Controls Data Inconsistency Maintains uniform and accurate data by ensuring that any update is reflected consistently throughout all related records. Juniper Business Use Only.

[Audio] Facilitates Data Sharing Allows multiple users and applications to access and use the same data simultaneously, supporting collaboration and integration. Enforces Data Standards Promotes uniformity by applying consistent naming conventions, formats, and rules across the entire database. Enhances Data Security Protects sensitive information through user authentication, access controls, and permission management, allowing only authorized access. Maintains Data Integrity Ensures accuracy and reliability of data using constraints (like primary and foreign keys) and referential integrity rules. Improves System Performance and Efficiency Provides faster data access, better resource utilization, and smoother data operations through centralized management and optimization. Disadvantages of Database While database systems provide numerous benefits, they also introduce certain challenges and limitations that must be managed carefully: Security Risks Without strong access controls and monitoring, sensitive data can be exposed to unauthorized users, leading to potential data breaches. Integrity Challenges If constraints and validation rules are not properly enforced, data accuracy and consistency may be compromised. High Hardware Requirements Large and complex databases often require additional storage capacity and powerful servers to operate efficiently. Performance Overhead Complex queries, large data volumes, or multiple concurrent users can slow down system performance and increase processing time. System Complexity Database management systems are inherently complex, requiring skilled administrators and developers to configure, optimize, and maintain them effectively.
