The primary of the Oracle 12c certification exams to enter manufacturing is 1Z0-061: Oracle Database 12c: SQL Fundamentals. Oracle College put this examination into manufacturing virtually concurrently with the retirement of the a lot older examination 1Z0-007: Introduction to Oracle9i SQL. Nonetheless, the 11g model of the SQL Fundamentals examination, 1Z0-051, remains to be out there. Having two equal exams in manufacturing results in a good quantity of confusion amongst certification candidates. On this article I’ll talk about the 2 exams, what’s totally different between them, and the way to decide on one over the opposite.
Both will fulfill the SQL requirement for the “Oracle Database 11g Administrator Licensed Affiliate” or “Oracle PL/SQL Developer Licensed Affiliate” tracks. The SQL requirement may also be glad by passing 1Z0-047: Oracle Database SQL Professional. Nonetheless, 1Z0-047 is a significantly tougher examination than both 1Z0-051 or 1Z0-061. That is an choice that ought to solely be thought-about in case you have labored with Oracle SQL extensively. This text focuses on the SQL fundamentals exams.
The 11g and 12c SQL Fundamentals exams are virtually equivalent when it comes to content material coated and necessities glad for Oracle certifications. Oracle doesn’t require you to make use of the 12c SQL Fundamentals when pursuing the 12c DBA observe or the 11g examination for the DBA observe in that launch. Any Oracle SQL examination (together with retired ones) can be utilized for any Oracle certification observe that has a SQL requirement. For instance, the SQL take a look at I took over a decade in the past was 1Z0-001: Introduction to Oracle: SQL and PL/SQL. That take a look at has been retired for years, however might nonetheless be utilized for the 12c observe.
Whereas the content material of the 2 exams could be very comparable, there are a couple of variations. Each 1Z0-051 and 1Z0-061 comprise forty-one subjects. Of these, thirty-six are frequent to each exams. This implies the exams have about 88% commonality by subject rely. The final part of the 11g examination (Creating Different Schema Objects) was faraway from the examination within the 12c model. The subjects coated in that part are:
- Create easy and complicated views
- Retrieve information from views
- Create, keep, and use sequences
- Create and keep indexes
- Create personal and public synonyms
For the 1Z0-061 examination, Oracle College added a brand new ‘Introduction’ part with the next 4 subjects:
- Describe the options of Oracle Database 12c
- Describe the salient options of Oracle Cloud 12c
- Clarify the theoretical and bodily features of a relational database
- Describe Oracle server’s implementation of RDBMS and object relational database administration system (ORDBMS)
Additionally they added yet one more subject to the “Managing Tables utilizing DML statements” part:
- Truncate information
I’ve to say that I’m very dissatisfied with Oracle College’s choice to place TRUNCATE (which is a DDL operation) below a piece particularly about DML statements. This isn’t one thing that is sensible in a take a look at designed for people who find themselves new to SQL. I’m positive that OU could be heartbroken to be taught of my disapproval.
The 1Z0-061 examination has 9 extra questions than 1Z0-051 (75 vs 66) and a barely increased passing rating (65% vs 60%). This doesn’t essentially imply that the take a look at is tougher to move, although. The subjects which were added are ones which are prone to have questions which are extra simple than the subjects that have been eliminated. OU has a sure goal proportion of candidates that they wish to move every take a look at on a primary try. In the event that they raised the passing rating, it was as a result of they felt the up to date take a look at had simpler questions.
I’ve to say that selecting one take a look at over the opposite is known as a toss-up. The 11g examination just isn’t significantly dated and the entire subjects are nonetheless related. There is likely to be a bit of little bit of long-term profit in having the 12c examination in your file relatively than 11g, just because 12c might be round after 11g is retired. Nonetheless, 11g is presently the usual database utilized in manufacturing environments. Only a few firms could have moved to 12c but. As well as, none of my employers have inquired (or cared) in regards to the particular exams I took to realize my Oracle certifications. Choose the examination that makes essentially the most sense to you and you may be assured that you’re not making a mistake. Whichever one you select, good luck on the take a look at.
