Hi all,
currently I try to investigate what are the consequences for me as a consultant working on a CRM project using HANA as primary data base. I will have some HANA-SQL-courses in May, but I have some questions in upfront:
- are the database tables (e.g. ORDER-tables like CRMD_ORDERADM_H) are created as row- or column-based tables?
- if they are created as row tables: Maybe I want to create some analytic reports based on the order data. If I want to use a column based table for that, I surely would have to create one, and fill it with my order data from the row based table(s). Sinde the transsactional processing will change only the OLTP-row-based tables, I am wondering if I can keep the OLAP-column-based tables in sync with the OLTP-tables. Is there a possibility to sync those tables automatically?
- will the select statements to access the order tables will change, or will they stay the same?
Cheers
Chris
