In this training program, learners will acquire proficiency in the fundamentals of SQL in Oracle environment. You will also develop the skills to write queries, modify data statements and define data structures.
No previous knowledge is required to complete the training program.
Writing SQL queries is no longer required only for software developers, and is increasingly expected in the fields of analysis, design, testing or reporting.
In our course, learners will learn the basics of SQL, be able to understand complex queries and write them independently. Our learners will also learn about Oracle data types and data modifying statements and defining simpler data structures. In addition to standard SQL statements, participants will learn about Oracle's features and will be able to work effectively with several tools. During the comprehensive program we put a strong emphasis on the acquisition of practical knowledge, so participants will learn SQL statements through examples.
