The SAP Web Development Workbench supports Calculation views. Calculation views are used in SAP HANA to perform complex calculations and aggregations on data from multiple tables. They allow users to define and execute complex calculations and transformations on data, making it easier to analyze and derive insights from large datasets. Calculation views are an important tool in SAP HANA for building analytical applications and performing advanced data analysis.

SAP recommends using the Calculation view because it allows users to perform complex calculations and aggregations on data from multiple tables. Calculation views provide a flexible and powerful way to analyze data by combining various data sources and applying calculations, filters, and aggregations. This type of view is especially useful for creating reports and dashboards that require advanced calculations and data transformations.

Column tables are more efficient when there is lots of repeating data values in columns. This is because we can remove all duplicates of each value and in place use binary integers for a smaller footprint and faster processing.

SAP HANA does not use predefined aggregates. This means that SAP HANA does not rely on pre-calculated or pre-aggregated data to perform queries and analysis. Instead, it uses an in-memory computing technology that allows for real-time processing of large volumes of data. This enables users to access and analyze data without the need for pre-aggregations, resulting in faster and more flexible data analysis.
