Home -> Community -> Mailing Lists -> Oracle-L -> Re: Know 1 database, know them all?
There seems to be something that you miss in this discussion: Writing
applications!
It's very likely very true, that you can use your DBA skills from one database and apply them on another, but many application developers have truely failed to understand that the different databases are very different in how you treat them well. Even the most simple applications that do nothing but 'select * from tab where primary_key=<something>' can be coded efficiently against one database, where the same code will neither perform nor scale if executed against the other database.
The converse is fortunately also true: With a well chosen design and well chosen application coding principles, you can write applications that both run, perform and scale on multiple different databases and at the same time are relatively portable between them. At the very least, the well chosen design will allow you to clearly distinguish portable from non-portable code.
