Hello people, can anyone help me about the available database developer certifications?Oracle's site is a bit chaotic and I found many options.For example:

Oracle PL/SQL Developer Certified Associate Certification
Oracle Database SQL Certified Associate Certification
MySQL 5.6 Developer Certification

Also are there any study guides for these?

All of them are good certification you can choose any one of them, Certification is justifying a way for professionals like IT employees to validate their knowledge and obtain credibility that will lead a candidate to better opportunities.

Oracle PL/SQL Developer Certified Associate Certification
  PL/SQL is the programming language supported for writing Stored Procedures in Oracle. PL/SQL expertise is often demanded by employers, although I personally recommend avoiding stored procedures if possible.

Oracle Database SQL Certified Associate Certification
 Presumably this is supposed to indicate that you have mastered the SQL language as it applies to Oracle databases.

MySQL 5.6 Developer Certification
 MySQL is a former open-source DBMS. It is not overly compatible with Oracle (less so than PostgreSQL), but an awfully large part of the Internet has been built on MySQL. Because a lot of people felt uncomfortable about Oracle having control of such a sensitive asset, MySQL was forked into the open-source MariaDB. At the moment, the two products are pretty much interchangeable, but time will tell. Oracle also bought OpenOffice, but that caused a fork producing LibreOffice. I think OpenOffice has since been donated to the Apache Foundation.

Oracle has certificate training courses, usually expensive ones, and if I remember aright, some of them are on-line courses, although I did Oracle Financials at one of their regional facilities. If your budget is more limited, a quick Internet search should yield a wealth of other alternatives. And, of course there are books, including books from Oracle Press.

My background is in Oracle PL/SQL. It is relatively simple compared to Java, so if you put the time in you can come away with a nice cert.

A few words of caution, there are limited resources for studying Oracle online, but there are lots of good textbooks.

Also, the practice tests available are not as cheap or as plentiful as the Java versions.

And finally I feel there are not as many PL/SQL jobs around as there used to be, but yes it is a good compliment to Java if you work for a large organisation that can afford the Oracle license.

The SQL exam is just SQL as it is implemented in Oracle.
