You Will Learn How To
- Design, build and query a relational database
- Capture the structure of an existing database with a CASE tool
- Develop a data model to describe an application's data
- Apply normalisation to data for effective, stable database design
- Build a relational database from the logical database design
- Access data in a relational database using simple SQL queries
Course Benefits
Relational databases often drive company-critical and Web-enabled applications. Creating a database design that accurately and completely captures user requirements is vital for success. This course provides a comprehensive foundation for designing, building, and working with relational databases, enabling you to participate in the development process and to effectively use relational databases in your environment.
Who Should Attend
Anyone involved in designing, building and using relational databases, implementing database applications, or managing database development projects.
Hands-on Training
A continuing case study provides you with the skills to analyse, design, build and work with a relational database. Exercises include:
- Analysing an existing database with a CASE tool
- Developing data models
- Creating a logical data model that identifies entities, attributes and relationships
- Normalising data to create stable table structures
- Exploiting a CASE tool to generate SQL
- Building a database to correspond to a logical database design
- Constructing simple SQL queries to access the database
