Dimensional modeling
In the context of PHP development, jobs requiring dimensional modeling skills are found in the fields of business intelligence (BI), data analytics, and data warehousing. These roles involve building applications that either populate or consume data from databases designed specifically for efficient querying and analysis.
PHP in a Data-Driven Environment
A PHP developer in this area may be responsible for writing ETL (Extract, Transform, Load) scripts that collect data from operational systems (e.g., a production MySQL database) and load it into a data warehouse. Alternatively, they might build reporting dashboards or APIs that query the data warehouse to provide insights to business users.
