Comprehensive and Detailed Explanation From Exact Extract:

In SAP HANA, the choice of storage type and load unit depends on access patterns, table size, and usage frequency.

Here’s how each part applies:

A. "Storage Type" to "Row Store" – This is correct.Since:

The table is accessed by only one program.

The program runs rarely.

The access pattern is row-oriented (SELECT SINGLE with filters).

Row store is more suitable for rare access with small result sets and no aggregation.

D. "Load Unit" to "Page Loadable" – This is correct.Since the program runs infrequently, loading the entire column into memory (column loadable) is not efficient. Page-loadable units load only required parts into memory on demand, which reduces memory footprint.

Incorrect options:

B. "Storage Type" to "Column Store" – Incorrect here. Column store is ideal for frequent reads, aggregations, or analytics, not for rarely accessed tables with simple lookups.

C. "Load Unit" to "Column Loadable" – Also not optimal for rarely accessed data. Column loadable preloads entire columns into memory, which is memory-intensive and unnecessary in this case.
