Evaluation of Sql Performance Tuning Features in Oracle Database Software

Timely access to data is one of the most important requirements of database management systems. Having access to data in acceptable time is crucial for efficient decision making. Tuning inefficient SQL is one of the most important elements of enhancing performance of databases. With growing repositories and complexity of underlying data management systems, maintaining decent levels of performance and tuning has become a complicated task. DBMS providers acknowledge this tendency and developed tools and features that simplify the process. DBAs and developers have to make use of these tools in the attempt to provide their companies with stable and efficient systems. Performance tuning functions differ from platform to platform. Oracle is the main DBMS provider in the world, and this study focuses on the tools provided in all releases of their software. A thorough literature analysis is performed in order to gain understanding of the functionality and assessment of each tool is performed. It also provides insight into factual utilization of tools by gathering responses through the use of an online survey and an analysis of the results
