• Key Concepts: 
  Data compression ratio is a measure of the amount of data that can be compressed in SAP HANA. It is calculated by dividing the size of the uncompressed data by the size of the compressed data. The higher the ratio, the more efficient the compression. 
  
  How to use it: 
  Data compression ratio is used to determine how much space can be saved when compressing data in SAP HANA. It is important to note that not all data can be compressed, and some data may not compress as efficiently as others. Therefore, it is important to consider the type of data being compressed when determining the compression ratio. 
  
  Tips & Tricks: 
  When compressing data in SAP HANA, it is important to consider the type of data being compressed and its size. Compressing large amounts of data can take a long time and may not yield a high compression ratio. It is also important to consider the type of compression algorithm being used, as different algorithms may yield different results. 
  
  Related Information: 
  Data compression is an important part of managing large amounts of data in SAP HANA. It can help reduce storage costs and improve performance by reducing the amount of data that needs to be processed.
