Top 105 Questions You Need to Know
Okay, now let’s get into the meat of the matter: the questions. There are literally hundreds of potential DES 105 questions out there, but we’ve compiled a list of the top 105 that you absolutely need to know. These aren’t just random queries—they’re the ones that pop up most often in exams and interviews. Ready? Let’s go!
Category 1: Data Modeling
Data modeling is the foundation of data science, so it’s no surprise that it’s a major focus in the DES 105 test. Here are a few questions to get you started:
- What is a database schema, and why is it important?
- Explain the difference between a relational and non-relational database.
- How do you normalize a database, and why is normalization important?
These questions might seem basic, but they’re designed to test your fundamental understanding of data structures. Don’t underestimate them!
Category 2: SQL Queries
SQL is the bread and butter of data engineering, so it’s a big deal in the DES 105 test. Here are some common SQL-related questions:
- Write a query to find the top 5 customers by total spending.
- How do you handle null values in SQL?
- Explain the difference between INNER JOIN and OUTER JOIN.
SQL might seem intimidating at first, but with practice, you’ll be writing queries like a pro in no time.
Preparing for the DES 105 Test
Now that you know what to expect, let’s talk about how to prepare. Preparing for the DES 105 test isn’t like cramming for a history exam. It requires a strategic approach that combines practice, study, and real-world application. Here’s how you can get started:
Step 1: Understand the Syllabus
Before you dive into the questions, make sure you understand the syllabus. The DES 105 test covers a wide range of topics, so it’s important to know exactly what’s expected of you. Break down the syllabus into manageable chunks and tackle each section one at a time.
Step 2: Practice, Practice, Practice
There’s no substitute for practice when it comes to mastering the DES 105 questions. Take as many practice tests as you can, and don’t be afraid to make mistakes. Every wrong answer is a learning opportunity!
Step 3: Use Real-World Examples
Applying your knowledge to real-world scenarios is one of the best ways to prepare for the test. Look for case studies, projects, or even personal challenges that require you to use your data skills. The more you practice in real-life situations, the better you’ll perform on the test.
Common Mistakes to Avoid
Let’s face it: everyone makes mistakes when preparing for a big test. But some mistakes are more costly than others. Here are a few common pitfalls to avoid when studying for the DES 105:
- Over-relying on memorization: It’s tempting to memorize answers, but that won’t get you far in the real world. Focus on understanding the concepts instead.
- Skipping practice tests: Practice tests are your best friend. They help you identify weak areas and improve your time management skills.
- Ignoring real-world applications: The DES 105 test is all about applying your knowledge. Don’t skip the practical stuff!
Remember, preparation is key. The more you practice, the better you’ll perform on test day.
