Ever wonder why so many astronomy apps are so hard to use? We do. So we made Classic Sky Map simple and intuitive enough for anyone to enjoy. The user interface is beautiful and straightforward, the controls are easy to use and most settings are just a tap or two away. Classic Sky Map shows you thousands of the brightest stars, the Moon, planets, constellations, meteor showers and more. And it's painless. Free Features: - Live Tracking. Simply point your device toward the stars and the sky map aligns itself automatically, showing you the portion of the sky at which you are looking. If your device has a compass, Classic Sky Map uses it automatically. If not, you can tell Classic Sky Map where the North is, and it aligns the sky map accordingly. - Live Earth Map. Quickly jump from one city to another by tapping on a map that shows the Earth's day and night boundary in real-time. If you allow it, Classic Sky Map can detect your current location automatically. You can also create custom viewing locations in seconds. - Fast Forward and Rewind. Accelerate or reverse time to understand how stars and planets appear to move in the sky over a longer period of time. - Beautiful Constellation Images. We put a tremendous amount of work into creating beautiful constellation images inspired by antique engravings and aligning them precisely with the stars. - Sharing. Share snapshots of the sky map with your friends at the tap of a button. - Quick Help. Should you have any questions while using Classic Sky Map, a concise, illustrated user guide will help answer them quickly. Full Version Features (In-App Purchase): - Interactive Search. Simply type in a search field, pick an object from a list of matches, then point your device toward the sky. An arrow appears and guides you until you are pointing your device toward the object you selected. If the object is not yet visible in the sky, its next rise time is displayed. - Sky Events. Classic Sky Map shows a list of current sky events such as meteor showers, eclipses and more and helps you quickly locate them in the sky. - Night Vision. Classic Sky Map's night vision mode helps minimize loss of dark adaptation. And we went the extra mile to make it look great in cyan, orange or red. - Extra Information. Tooltips and an information panel show details about stars, planets, the Moon, meteor showers and more. - Personalization Options. Personalize your sky map by turning various guides and display options on or off. Have fun!

WHAT'S INSIDE - 500 practice questions, each with an explanation of why the answer is right - All 14 knowledge areas — Data Governance, Data Architecture, Data Modelling & Design, Data Storage & Operations, Data Security, Data Integration & Interoperability, Document & Content Management, Master & Reference Data, Data Warehousing & BI, Metadata Management, Data Quality, Big Data, Data Ethics, Data Management Process - A mock exam that follows the official blueprint: 100 questions drawn at the real exam's weighting, 90 minutes on the clock — or 110, the allowance the CDMP gives when English is not your main language - Results graded the way the exam grades them — Associate 60%, Practitioner 70%, Master 80% BUILD THE QUIZ YOU NEED - Draw from everything, from questions you have not seen yet, from the ones that need work, or from your bookmarks - Choose the knowledge areas, the length and the question range - Time each question, time the whole quiz, or turn the clock off SEE WHERE YOU STAND - Accuracy per knowledge area, so revision goes where it is weakest - Sessions, average score, best score, answers given, day streak and a score trend - A mistakes bank that collects what you got wrong and hands it back as a quiz - Full history of every session, with every answer reviewable STUDY AND SEARCH Search the whole bank by wording or topic, filter by area, by bookmarked or by not seen yet, sort by best match, question number or weakest first — then practice the exact set on screen. Also: dark mode, an optional reveal-answer button, the extra-time setting for non-native English speakers, and a quiz that resumes where you left it. FREE TO TRY, ONE PAYMENT TO OPEN Every feature is free: mock exam, statistics, mistakes bank, bookmarks, search, history. What the free version limits is the question bank — you get 2 questions from each of the 14 knowledge areas, enough to see exactly how the app works. A single in-app purchase unlocks all 500 questions for good. It is not a subscription, nothing renews, and it restores on any device signed in to the same App Store account. YOUR ACCOUNT Sign in with email, Google or Apple. Your answers, scores and settings stay on your device. You can delete your account at any time from Settings — it takes effect immediately and your study data is erased with it. INDEPENDENT STUDY AID DataMaster Prep is not affiliated with, endorsed by or certified by DAMA International. The questions are practice questions written for this app, not past exam papers, and practising here is not a guarantee of passing.
