Oracle is a relational database management system (RDBMS) that provides the following main functions: data storage and management (relational model) data integrity (constraints, indexes, transactions) data security (authentication, authorization, Encryption) Data Processing (SQL Query Engine) Data Analytics (Dashboards, Reports, Visualizations) Scalability and High Availability (Redundancy, Failover) Cost Effectiveness (Low Cost of Ownership, Licensing Options)
The role of Oracle
Oracle is a powerful relational database management system (RDBMS) with a range of features and benefits that make it an important Very popular among organizations.
Main functions:
Data storage and management:
- Provide a structured and efficient way to Store, organize and manage large amounts of data.
- Use the relational model to organize data into tables, rows and columns to facilitate data query and retrieval.
Data Integrity:
- Ensure data accuracy and consistency through constraints, indexes, and transactions.
- Maintain the integrity of data relationships and prevent incorrect insertion, update, or deletion.
Data Security:
- Provides authentication, authorization, and encryption capabilities to protect data from unauthorized access.
- Allow administrators to define user permissions and control access to sensitive data.
Data Processing:
- Provides a powerful query engine for executing complex SQL queries to retrieve, update and delete data.
- Supports advanced data types such as JSON, XML and spatial data.
Data Analysis:
- Built-in data analysis tools, such as Oracle Analytics Server, provide deep data insights.
- Allows users to create dashboards, reports, and visualizations to showcase trends and patterns in data.
Scalability and High Availability:
- Supports a wide range of deployment sizes from small applications to large enterprise environments.
- Provides redundancy and failover capabilities to ensure that data and applications remain available even in the event of hardware or software failure.
Cost-effectiveness:
- Has a lower cost of ownership relative to other enterprise-level database systems.
- A variety of licensing options are available to suit different budgets and business needs.

Oracle's product ecosystem includes databases, middleware and cloud services. 1. OracleDatabase is its core product, supporting efficient data storage and management. 2. Middleware such as OracleWebLogicServer connects to different systems. 3. OracleCloud provides a complete set of cloud computing solutions.

MySQL and Oracle each have advantages in performance, scalability, and security. 1) Performance: MySQL is suitable for read operations and high concurrency, and Oracle is good at complex queries and big data processing. 2) Scalability: MySQL extends through master-slave replication and sharding, and Oracle uses RAC to provide high availability and load balancing. 3) Security: MySQL provides fine-grained permission control, while Oracle has more comprehensive security functions and automation tools.

Oracle is called the "Powerhouse" of database management because of its high performance, reliability and security. 1. Oracle is a relational database management system that supports multiple operating systems. 2. It provides a powerful data management platform with scalability, security and high availability. 3. Oracle's working principles include data storage, query processing and transaction management, and supports performance optimization technologies such as indexing, partitioning and caching. 4. Examples of usage include creating tables, inserting data, and writing stored procedures. 5. Performance optimization strategies include index optimization, partition table, cache management and query optimization.

The development history of Oracle software from database to cloud computing includes: 1. Originated in 1977, it initially focused on relational database management system (RDBMS), and quickly became the first choice for enterprise-level applications; 2. Expand to middleware, development tools and ERP systems to form a complete set of enterprise solutions; 3. Oracle database supports SQL, providing high performance and scalability, suitable for small to large enterprise systems; 4. The rise of cloud computing services further expands Oracle's product line to meet all aspects of enterprise IT needs.

MySQL and Oracle selection should be based on cost, performance, complexity and functional requirements: 1. MySQL is suitable for projects with limited budgets, is simple to install, and is suitable for small to medium-sized applications. 2. Oracle is suitable for large enterprises and performs excellently in handling large-scale data and high concurrent requests, but is costly and complex in configuration.

Oracle helps businesses achieve digital transformation and data management through its products and services. 1) Oracle provides a comprehensive product portfolio, including database management systems, ERP and CRM systems, helping enterprises automate and optimize business processes. 2) Oracle's ERP systems such as E-BusinessSuite and FusionApplications realize end-to-end business process automation, improve efficiency and reduce costs, but have high implementation and maintenance costs. 3) OracleDatabase provides high concurrency and high availability data processing, but has high licensing costs. 4) Performance optimization and best practices include the rational use of indexing and partitioning technology, regular database maintenance and compliance with coding specifications.

Steps to delete the failed database after Oracle failed to build a library: Use sys username to connect to the target instance. Use DROP DATABASE to delete the database. Query v$database to confirm that the database has been deleted.
