We just got back as well and boy are there so many opinions on HANA, the roadmap, etc. We decided to place this topic and group all questions we've read from earlier posts along with what other customers were saying and asking.
1. Does SAP HANA replace BI?
The way we look at this is BWA came out around 4-6 years ago (if we recall correctly). Of the 15,000+ customers that have BI installed, how many adopted BWA (have implemented and using)? Can this same conversion rate be said for HANA (meaning only a certain % of customers that either have BWA already or don't have BWA (so never implemented BWA) will implement HANA)?
It sounds like there will almost be 2 Data Warehouse solutions with SAP going forward. Traditional BI the way it exists now and then HANA. With HANA you get real-time data and instant query performance. From what we've read and heard this past week a "HANA BI" will be a new set of tools to develop reporting solutions. Now, how about all the transformation that currently occurs in traditional BI. Updating to a cube there is most of the time some transformation, lookups, that happen to create a record. Sure, HANA is in memory, but this same type of data transformation must happen to create a single record in some type of "InfoProvider" that BOBJ can read from and display in, for example, SAP Dashboarding, Crystal, Webi.
I have not seen or heard one explanation into the "SAP HANA" Data Warehouse approach. Can someone comment regarding this most important point 1?
2. Will SAP continue 5-10 years down the road to support "Traditional BI"?
We don't see moving to HANA. Sure concept sounds great, but we didn't see the need for BWA (data volume just not there) and we don't see the need for HANA. We have less than 1% of our BI applications we need updated more regular than nightly. So these exception solutions we load several times throughout the day. This works for us.
3. What does this mean for our RDBMS, meaning ORACLE?
Does HANA mean customers using ORACLE, for example, can remove this hardware piece altogether in the future? Side note: If your ORACLE, what in the world are you thinking?
4. Is HANA going to be adopted and implemented more quickly on the ECC side than BI side first?
We assume SAP will concentrate on the ECC side first, thus maybe making a decision to go to HANA a possibility. We really only hear what it does for BI, not ECC.
We could be confused, as everyone else, but I think the above would really clarify things for many.
