Store description excerpt
SQLD Learning That You Won't Forget. How you review, rather than how many problems you solve, determines your success. SQLmate is not just an app that increases the number of problems. It focuses on pinpointing your current weaknesses and bringing you back problems you've already solved just before you forget them. Because the cognitive science-based FSRS algorithm analyzes the forgetting curve for each problem to automatically determine the optimal review time, the amount of information retained differs significantly even with the same amount of time invested. [Key Features] Concept Learning If you feel overwhelmed by the task of solving problems, start by reviewing the concepts. The entire range of SQLD is divided into 138 lessons for sequential learning, and you can immediately verify your understanding of learned concepts through practice problems. 4,602 Problems, Entire SQLD Range From understanding data modeling to SQL basics and applications. Produced in-house to reflect KDATA's official exam standards. Detailed Explanations Explanations are provided for every problem. You can move on without simply checking the answer, understanding the concepts behind why that answer is correct. While in-depth detailed explanations are a premium feature, you can open them for free the first five times to check them out yourself. SQL Practice Area You can skip directly from the explanation and run the query for the problem yourself. The problem table is already uploaded, so it opens in your browser without installation or login. Try changing the conditions to see how the results change. Various Solution Modes You can choose to solve problems by subject or chapter. You can start with unsolved problems or gather only your weak chapters to focus on. A chapter-by-chapter shuffle mode that mixes problems from all subjects is also provided for free. FSRS Smart Review It extends the review interval for questions you answer correctly and quickly shows you frequently missed questions again. You don't need to create a review schedule yourself; the app takes care of the problems you need to review today. Review Notifications With daily study reminders and FSRS review time notifications, it helps you maintain your study flow so you can revisit them just when you are about to forget. Weakness Analysis Heatmap View the correct answer rate for each specific chapter at a glance. You can identify your weak areas by color and move directly to the solutions for that chapter. **Incorrect Answer Notes and Review Box** Gather your incorrect answers and questions to review in one place. You can review by grouping them by cause, such as trap types, SQL syntax, or out-of-range errors, and leave your own notes for each question. **Practical Mock Tests** We provide 10 sets of 50-question, 90-minute tests, just like the actual exam. Scoring is based on a passing score, and your highest score and test history are managed. **Learning Statistics and Continuous Stud
