AdSense braindump/gunmen filter

Today's post will continue the braindump subject started two days ago. Yesterday I had small e-mail exchange with CertGuard CEO Robert Williams concerning the ethics of AdSense in the context of braindump or gunmen sites. It happened to me many times that browsing some good, valuable certification web-pages I've noticed Google AdSense ads of those sites.

Let's see an example. Below there is a screenshot with advertisements published on CertCities:



These ads are just next to the article about Certification Ethics (sic!). For those who still do not understand - when you click there you will be redirected to the website maintained by the criminals offering taking exams for people that have no knowledge of the testing materials. And moreover - CertCities will get some money for your click from these bad guys. Does this mean that CertCities is popularizing dirty business?

Actually I am not the only one who is surprised.

CertCities is one of the best site about certification. No doubt. This post is not meant to be an attack, it's just an example. I'm going to publish AdSense in the future as well so I will have to deal with the same problem.

As for now I see one solution. Google offers Competitive Ad Filter. It lets you create your own set of sites the ads of which you do not want to publish on your site. Unfortunately it is limited to 200 URLs, but I think it's still worth a shot.

One can get the list of braindump and gunmen sites from CertGuard organization if one will be recognized as legitimate. Please contact CertGuard in the matter of obtaining the filter list.

What is braindump?

While browsing the web for exam preparation help, the newbie can easily notice the word "braindump".
This post explains what's that, why it is evil and how to avoid it.

In general the term "brain dump" (braindump, brain-dump) is used for the situation when one person reports everything he or she knows about certain subject.

In the context of certification exams "braindump" means the act of memorizing the real exams questions and then writing them down in order to sell such sets of questions. This is done by people being payed especially for sitting the exams and remembering their content.

Braindump is the crime.
Braindump is cheating.
Using braindumps leads to the situation that everybody can get certified by just cramming for any exam with no having any understanding of the subject. More people passing the exams in this way, less valuable is the certification on the job market.

Q:
I want to buy preparation materials from X Company. How can I assure myself that they offer braindump-free, good piece of work?

A:
There is an organization which maintain the list of cheating companies, it is called CertGuard . They provide the search tool. Just enter the URL address of X Company and check its credibility.

Today I dug out few very interesting articles written by Howard Fosdick on DBAzine.com

One of them compares Oracle, DB2 and SQL Server certifications.

There are also few articles containing quite helpful tips about studying and passing the tests. Complete archive of Howard's posts on DBAzine can be found here.

MySQL will train and examine Oracle DBAs for free

In the middle of August MySQL will organize MySQL DBA Boot Camp which is one-day training "designed for senior-level Oracle DBAs to get quickly familiar with MySQL database concepts and best practices". Each participant will also get free exam voucher and free exam guide.

This opportunity is limited to 200 DBAs and lessons take place only in two US cities - too bad...
However "free, online version of these workshops will be made available later in August", they promise.

Oracle certificates

Let's start with Oracle as I'm going to take one of their exam soon. Oracle offers wide range of exams. There exist 3 main levels of certification programs:



Higher the certification title, more exams one has to pass. To get Oracle Certified Associate (OCA) title it is enough to pass one or two exams, depending on the chosen certification path. For most of Oracle Certified Professional (OCP) and Oracle Certified Master (OCM) certifications some additional actions are required like completing hands-on courses (online or in-class) and finally submitting special forms.

Depending on what topic you are interested in, you can choose between various paths of certification. They distinguish 4 different knowledge areas:

  • Database
  • Middleware
  • Applications
  • Linux

Example:

Suppose that you have SQL at your fingertips and you want to go for one of Middleware paths:
Oracle PL/SQL
Developer Certified Associate.
You have to pass 2 exams:

Step 1)

1Z0-001 Introduction to Oracle: SQL and PL/SQL
($125 USD, 120 minutes, 57 questions and 68% is the passing score)

alternatively

1Z0-007 Introduction to Oracle 9i SQL
($95 USD, 120 minutes, 52 questions and 71% is the passing score)
Step 2)

1Z0-147 Program with PL/SQL
($125 USD, 90 minutes, 66 questions and 77% is the passing score)

Steps 1 and 2 exams can be completed in the opposite sequence.

If you need training Oracle website will guide you. There are also few books designed especially for helping to prepare for certain exams. I think that customers' reviews at amazon.com are quite helpful to make a good choice. However some people say that the best reference is just Oracle docs. Anyway we assumed that you are an expert already :) Register online for the exams and choose the Test Site in the location you like. Don't worry, there are many of them everywhere in the world, for example 85 in India, 26 in Brazil, 17 in Poland and even 1 in Cambodia.

Note that there is also a possibility to take some exams online (non-proctored).

You registered, went to the testing center (or to online test platform) and passed 2 exams. Congratulations you just became the Oracle PL/SQL Developer OCA!
Wanna have an OCP title? No problem, take one more exam:

1Z0-141 Oracle Forms: Build Internet Applications
($125 USD, 120 minutes, 69 questions and 75% is the passing score)

and you are Oracle Forms Developer Certified Professional.

To summarize, 3 exams has to be passed to receive OCP. In this case it's finished, there is no OCM level in this certification path.

In other cases it is not that easy. For example for Oracle 9i Database Administrator OCP there are 4 exams and one training required (however for 10g it's only two exams).

To get OCM is a different story. As this is suppose to be the most advanced certification, the exam has some special rules. First of all it cost $2000 USD and lasts 2 days. They recommend to take it when having at least 3-4 years of professional enterprise-level Oracle experience. The exam consists in working and solving some problems on real machines. Non-searchable Oracle documentation set is available. Have a look - these people got it.

Except for three main certification tiers described above, Oracle offers Oracle Special Accreditation specifically aimed at OCPs who want to certify themselve in some advanced areas.

Additionally this year they launched Oracle Certified Expert Program which is suppose to be "
new type of specialization certification program from Oracle, which grants credentials that recognize competency in specific technologies, architectures or domains not currently covered in the path-based Certified Associate and Certified Professional certifications".

That's all for now, promise to describe my experiences in details after taking one of exams.
