Studying for the 1Z0-450 – Oracle Application Express 4: Developing Web Applications

The 1Z0-450 exam is one of Oracle’s niche certifications. It is pursued largely by Oracle developers that specialize in using Application Express for creating Web interfaces in Oracle, or by new IT professionals that are looking to enter that area. I have worked with Application Express since the early releases when it was called HTMLDB. It is a robust development environment and well suited to rapidly creating database applications without sacrificing the ability to make them highly functional. This is a very useful certification for an Oracle database developer to have. This article will provide you some insight into some of what will be expected from you on the test to help guide your preparation.

All of the topics that will be covered in the 1Z0-450 exam are listed on the Oracle Education website. Any capabilities of Application Express that are not listed will not appear on the test. The lists from Oracle Education will always be definitive. The Developing Web Applications exam contains sixty-four topics in nineteen subject areas. The vast majority of them are specifically related to creating an application using Apex. The remaining topics deal with utilities, supporting applications, and interacting with the database.

During my Oracle career I have taken eleven Oracle certification tests. If I were to pick a single exam that was least like the others, it would be this one. As a general rule, Oracle certification exams are primarily about recognizing key facts and features of the subject being tested. The 1Z0-450 exam has a good percentage of questions that fall into this category, but it also has a significant number of questions that exist only to verify your familiarity with the Application Express interface. In a perfect world, the exam would have simulations that would test a candidate’s knowledge of the interface. Since this test has no simulator, it makes use of questions that try to verify that you know how to use the interface. Some of the questions ask you to sequence events: “What is the correct order of the six steps to create ‘X’ object.” Other questions ask what can or cannot be performed with the interface: “Which of the below functions is not possible on a ‘Z’ object?” Because questions like these are not key facts to be written down and memorized, it is not possible to study for them as such. In order to be prepared for this kind of question, you must be familiar with the interface. This means you must use Application Express enough to gain that familiarity.

Before you even consider taking 1Z0-450, you need to have used Application Express to create one or more database applications and one or more websheet applications. The applications don’t have to be incredibly complex, but you should practice creating one or two of every kind of form and report available. You likewise want to try creating some of all of the item types. There are numerous Oracle-By-Example tutorials for Application Express. Going through these tutorials can be useful. You will have to become reasonably familiar with just about all the features that exist in the environment. Take a look at the topics at the Oracle Education website. Plan to spend extra time learning about those areas that you use the least.

In order to have a good chance of passing the test, you must be fairly familiar with the Apex interface. If you have never used Application Express and are planning to simply read about it and pass 1Z0-450 without spending time using the development environment, you are almost assuredly going to be disappointed. I’ve been developing applications with it since 2004 and I did not find the test simple.

The exam has 55 multiple-choice or multiple-answer questions. At this time 61 percent is the passing score. For the multiple-answer questions, there is no partial credit. Not answering a question counts against your score as much as answering one incorrectly, so you don’t want to leave any question unanswered — even if that means simply picking a letter at random. The intent of 1Z0-450 is to pass only those people who really know the development environment. In my opinion, it does a reasonably good job of that. Good luck on the test.

Unusual Character Education Programs

You’ve no extra time to teach character education programs because you’re already a great model of your most cherished character traits.

You want your kids

  1. To be good students and good kids.
  2. To be healthy and loving.
  3. To have lots of friends. And
  4. You want a little peace of mind knowing you’ve done a darn good job preparing your children for adulthood.

Am I right so far? Excellent. You’ve come to the right place for help. But there’s one more character trait that your kids lack that often nags you.

Can you think of it? Come on, be honest. I know many people say you’re not supposed to want this, but deep in your heart, you do.

When’s the last time your kids made you breakfast in bed? (Mother’s Day doesn’t count).

Or cleaned their rooms without you yelling and screaming? Mostly, you want them to appreciate just a little what they have.

But is this realistic? Can young kids and children ever appreciate what their parents do for them? And should they?

Introducing kids to gratefulness is a difficult, challenging task. Yet, it’s possible to plant the seeds and someday they’ll sprout, rest assured.

Let me share one unusual character education lesson plan, based on character traits of extraordinary leaders, that shows how character education programs can plant the seeds for lifelong gratitude.

One character trait forms the foundation of this program.

  1. Kids who learn this trait (even if it doesn’t show up until adulthood), are guaranteed success of the heart.
  2. Nothing is more important for a successful life than one rich in being grateful for who one is and what one has.
  3. I’ll teach your children to begin to express gratitude for things they now take for granted. You may witness them become happier. This expands their hearts to love themselves and others.

How to Be Happier by Expressing Gratitude Daily

Have your children do the following steps. (Until the end of the lesson, I speak directly to your child, so print this out for her use).

Step 1: Buy a special notebook that is your Gratefulness Journal.

Step 2: Start a section called Gratefulness Inventory. (1 minute)

Step 3: Think of 5 things you have to be grateful for. For example, your house, your bed, your pet, your best friend, your clothes, your mind, etc. (3-5 minutes)

Step 4: Make a list of these 5 things. (3 – 5 minutes)

Step 5: Say to yourself or out loud: “I’m grateful for or I’m thankful for_______(each of the 5 things on your list). (2-3 minutes)

Step 6: Add 6 more things to your list. Things can be body parts, for example, “I’m thankful for my legs, I’m grateful for my eyes, I’m thankful for my brains, etc.” (3-5 minutes)

Step 7: Write a brief note (100 – 200 words) expressing gratitude and thanks to your favorite person or best friend in the whole wide world. (15 minutes)

Step 8: Send the note or give it to your favorite person. (2 minutes)

Step 9: Notice how you feel. Do you feel any different than when you began this exercise? Explain and share with mom if there is a difference. (3 – 5 minutes)

Step 10: Repeat 10 steps weekly for 3 months.

Mom, with your guidance and your child’s efforts, she’ll learn to like expressing gratitude regularly, because it makes her feel so good.

Article Summary

Autism Apps for Special Needs Education

Educational apps that have visual scene displays, are usually considered the best learning aids for children with autism spectrum disorder, especially the low-functioning communicators. Experts working with autistic children usually recommend “What’s the Expression” and “Make Sentences” apps that extend a detailed context to most of the common situations.

The “What’s the Expression” and “Make Sentences” apps convert symbols to speech and allows the less verbal autistic kids to communicate in a much better way. Several specialized educators focus on tools that gears around emotion for classroom support. Both these apps fit the bill in this regard. Many kids are lost in a social situation and the “What’s the Expression” and “Make Sentences” educational apps can help them out in such circumstances.

These days, assistive technology has come to the help of autistic children, both inside and outside the classroom. A big difficulty faced by children with autism spectrum disorder is that all the people may not be aware of their situation. An autistic child is likely to face problems while communicating with people in a social situation. But if a child is introduced to “What’s the Expression” and “Make Sentences” educational apps, he/she can negotiate the difficulties to a great extent.

Social situations are tough for autistic children. Even your neighborhood grocery store or the movie hall can be filled with distractions. These distractions can trigger and continue eliciting autistic behaviors, no matter what the situation is or how much improvement the child has made in his/her communication. Educational apps, undeniably, can ease the situation. These tools help children to communicate.

With the advent of the autism apps for children, societal factors are becoming less of an issue. This is because the special strengths of those having autism are beginning to be noticed.

Though the autism employment scenario for autistic people is not very rosy, some big multinational companies have begun hiring people with autism, things are far from what’s actually required to get all of them gainfully employed.

Assistive technology like autism apps are not only helping children affected with the disorder to learn, they are actually helping them survive and face their unique challenges. Apps like “What’s the Expression” and “Make Sentences” have become seamless components in their lives.

Experts are hoping that technology will become much more personalized in the future. The autism apps can be customized for each individual. The apps will become more intelligent to judge the intelligence of each child.
