No, since there was no other solution offering in-memory without changing the SQL syntax.

No we have built this on oracle.

Earlier, we utilized the Oracle Database Appliance for data warehousing purposes. Additionally, we relied on SQL databases, particularly older versions managed by Oracle as well as the old SAP DB. However, we transitioned to Oracle Database In-Memory to address the specific needs of our environment, particularly in scenarios where we needed to report data across distributed sites efficiently.

No, we always needed something like this, and I've looked at Microsoft, they have a similar solution, I think they have something similar,

I tested the In-Memory equivalent in DB2 or SQL Server 2014, but they both have limitations in their uses. SAP HANA is one of the most concurrent of Oracle’s solution, but I have never used it.

We've found another similar solution called Ignite that we are looking at implementing.

The solution was already in place when I began to work for the company. I don't know if they previously used a different solution or not.

We had started to use this solution from the beginning. We haven't switched from another solution. When selecting a vendor, we want someone who has a long term road map. This demonstrates sustainability.

There was no such software for Database prior to this.
