As a registered tutor on UrbanPro.com specializing in PL/SQL Training, I understand the importance of comprehensive knowledge in Oracle's PL/SQL and its various components, including synonyms. In this response, I will delve into the concept of synonyms in PL/SQL on Oracle.

Understanding Synonyms in PL/SQL: Synonyms in PL/SQL serve as aliases or alternate names for database objects, allowing for simplified and more readable code. In Oracle, synonyms are particularly useful for enhancing the overall clarity and manageability of a database.

Types of Synonyms in PL/SQL: There are two main types of synonyms in PL/SQL on Oracle:

  1. Private Synonyms:

    • Definition: Private synonyms are specific to a particular schema or user.
    • Use Case: They are useful when a user wants to reference an object owned by another user without specifying the owner's name each time.

  2. Public Synonyms:

    • Definition: Public synonyms are accessible to all users in the database.
    • Use Case: Public synonyms are handy when an object needs to be shared and accessed by multiple users without specifying the owner.

Creating Synonyms in PL/SQL: Creating synonyms involves the CREATE SYNONYM statement. Here's a basic syntax example:

sql
-- Creating a Private Synonym CREATE SYNONYM synonym_name FOR schema.object; -- Creating a Public Synonym CREATE PUBLIC SYNONYM synonym_name FOR schema.object;

Best Practices for Using Synonyms: When offering PL/SQL Training, it's essential to guide students on best practices for using synonyms in Oracle:

  • Clearly define naming conventions for synonyms to maintain consistency.
  • Encourage the use of synonyms for security and abstraction.
  • Emphasize the significance of updating synonyms when underlying objects are modified.

Online Coaching for PL/SQL Training: For individuals seeking the best online coaching for PL/SQL Training, consider the following key points:

  • Look for a tutor with extensive practical experience in PL/SQL development.
  • Ensure the coaching program covers not only basic concepts but also advanced topics like synonyms.
  • Check for hands-on exercises and real-world examples to reinforce learning.

Conclusion: In conclusion, synonyms in PL/SQL on Oracle play a crucial role in simplifying code and improving database manageability. As a dedicated tutor on UrbanPro.com, I emphasize the practical application of these concepts in real-world scenarios, providing students with valuable skills for their professional development.

I need your help to choose my career as I have three years of gap between my education. I know SQL. Can anyone tell me should I choose MS SQL server or oracle because I am interested in the database? Which one will be better to learn to get into the IT industry? Please help me! Thank you!
As you are strong and interested in SQL, why not to choose ETL Testing? It has a good career ahead in data projects. To survive in the market, you need both Oracle & SQL Server. Actually, both are almost same but are different products.
