TOP relational databases are MS-SQL, Oracle, and others. MS-SQL server is very compatible with normal companies for their Billing System, Customer care, Data management. Oracle Database is much more complicated than MS-SQL, but usually better for big companies with TB Data-s. Review collected by and hosted on G2.com.
I will say migrating Data-s to new Versions usually takes lots of time and knowledge. Review collected by and hosted on G2.com.
