Table aliasing is a widely used technique in SQL queries that enhances readability, scalability, and maintainability, particularly in complex queries involving multiple tables. This study examines the functional and semantic implications of aliasing, highlighting its role in improving query clarity, reducing redundancy, and facilitating long-term database management. While the benefits of aliasing are evident in large-scale applications, potential limitations exist. In simple queries, aliasing may be unnecessary and could even introduce confusion when non-descriptive or overly abbreviated aliases obscure the meaning of the query. Additionally, inconsistent alias usage can lead to readability issues and hinder collaboration among database developers. This paper provides a comprehensive analysis of aliasing best practices, explores its impact on query optimization across different relational database management systems (RDBMS), and discusses scenarios where aliasing may be either advantageous or counterproductive. The findings underscore the importance of adopting a strategic approach to aliasing to balance clarity and efficiency in SQL query construction.
