Category: Databases and SQL
The course provides students with knowledge and skills to create, manage and programmatically control database on Oracle platform. Basing on relational database theory students get to know SQL language. They learn to create complex queries, design well structured databases, use indexes to improve performance. Students practice every subject in hands-on lab.
The course outline is similar to course BD 101 (Databases for programmers). This course is designed to Oracle platform. Great value of dedicated courses is that students get used to dedicated tools and learn specific SQL dialect.
