I used Oracle DB for >10 years. After using C/C++/Assembly in my degree course I was trained in Oracle development tools by an investment banking consultancy. Oracle was/is very strong in enterprise companies in Banking/Utilities/Government/Defence/Retail. The database was always really solid and scalable and Oracle was probably the first modern relational database server multiplatform from the 90s onwards with great SQL dialect and PL/SQL enabled very fast data manipulation for ETL and business logic. Almost all Oracle products are free to download and play with and the tooling for building front end (client/server and web) were very easy to use and could provide useable (maybe not pretty) front end applications easily. There is a lot more competition now from SQLServer and Postgres but for a while Oracle was miles ahead. I'd still choose to use it as I have a greater knowledge of it than other db servers. It doesn't need to be that expensive if you have a small server especially for internal use APEX is great and it's all freely downloadable to evaluate.
