Jeanne Boyarsky wrote:If you want to be a software developer, I would say no. If you want to maintain databases, I would start with a different one as Mike noted.
Rahul Sudip Bose wrote:True, but i also see some job ads that say "PHP and MySQL". Is there any cert in oracle or ms-sql ? Can you suggest some books/links to begin the same ?
Why are ms-sql and oracle more popular than my-sql ?
Rahul Sudip Bose wrote:I dont know much about DB, so please bear with me if the doubts sound silly. I want to use/apply DB and perhaps have some knowledge of its internals but not make one. (Like knowing how to drive a car, few things inside the hood...but i dont want to be an automobile engineer ) What is meant by "maintaining a DB" ?
Jeanne Boyarsky wrote:
My concern about certifying in a database is that is sends the wrong message. If you do get one, make sure it is clearly a developer certification and not an administration one.
Jeanne Boyarsky wrote:
A DBA (database administrator) may code stored procedures/sql, but is not generally a developer. Here's a list of some DBA responsibilities.

chris webster wrote:Finally, I'm guessing that Jeanne simply meant that if your certificates tell people you're a "DBA", but you apply for a "developer" job, they may wonder if you really want to be a developer or a DBA. So forget about the certificates right now, and don't worry too much about all this stuff, just grab whichever DB seems suitable for you and get started!

Rahul Sudip Bose wrote:Saw some sites from the search...deleted MySQL.
--Now what to learn - oracle express or ms-sql express ?
--Do the free editions prepare one for handling the paid versions OR are they just "toy" versions and i will have to learn the paid versions from scratch, once in a job ?
--Which is easier for newbies to DB ?
--Do i have to learn about DB first(from say, korth & silberstaz) or i can jump directly to oracle or ms ?
