Most business and technical data consists of multiple tables with interlocking relationships. Such databases must provide reliable storage, transaction management, access security and multi-user support. In this course, you will learn the concepts and design for a Relational Database Management System (RDBMS) and focus on the Structured Query Language (SQL) to define and manipulate data.
The course covers how to create conceptual, logical and physical designs of relational databases in response to a set of user requirements. Instructions will be provided through the use of several case studies. You will learn design methodology, entity-relationship diagrams (ERD) and normalization principles. You will use an Oracle database to design the ERD and implement a working database. SQL is the query language used to access, maintain and share data with the relational database. You will learn methods for producing readable output, creating and manipulating tables and creating and managing constraints using SQL.
The concepts and SQL language learned here apply to all major RDBMS. You will gain understanding of the relational DB and have hands-on experience in creating database and working with data. The instructor recommends Oracle as an example database such as Oracle 12c, 11g Express or MySQL.
