Creating a new user in Oracle requires the following steps: Connect to the database. Use the CREATE USER statement to create a user and specify a password. Grants users specific permissions (such as SELECT). Reconnect with new users and test permissions.
How to create a new user in Oracle
Creating a new user in Oracle is an easy process that grants users the permissions they need to access the database and perform operations. Here are the steps to create a new user:
Step 1: Connect to the database
Use an Oracle database client such as SQL*Plus or SQL Developer to connect to the database server.
Step 2: Create a user
Create a new user using the following syntax:
<code class="sql">CREATE USER IDENTIFIED BY ;</code>
For example, to create a user named "new_user" with a password "mypassword", use the following command:
<code class="sql">CREATE USER new_user IDENTIFIED BY mypassword;</code>
Step 3: Grant permissions
If no permission is granted, the new user will not be able to perform anything. Grant specific permissions using the following syntax:
<code class="sql">GRANT ON TO ;</code>
For example, to grant "new_user" SELECT permission to the table "employees", use the following command:
<code class="sql">GRANT SELECT ON employees TO new_user;</code>
Step 4: Test permissions
Use the username and password of "new_user" to reconnect to the database. Then, try to perform the grant permissions to verify that the user has the required permissions.
Notice:
- Choose a strong password and keep it private.
- Grants only the minimum permissions required by the user.
- Consider granting roles after creating a user, because roles can easily manage permissions.

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.
