9-12.DA.9 (Computer Science)


Standard Identifier: 9-12.DA.9
Content Area: Computer Science
Grade Range: 9–12
Concept: Data & Analysis
Subconcept: Storage
Practice(s): Recognizing and Defining Computational Problems (3.3)

Standard:
Describe tradeoffs associated with how data elements are organized and stored.

Descriptive Statement:
People make choices about how data elements are organized and where data is stored. These choices affect cost, speed, reliability, accessibility, privacy, and integrity. Students describe implications for a given data organziation or storage choice in light of a specific problem. For example, students might consider the cost, speed, reliability, accessibility, privacy, and integrity tradeoffs between storing photo data on a mobile device versus in the cloud. Alternatively, students might compare the tradeoffs between file size and image quality of various image file formats and how choice of format may be infuenced by the device on which it is to be accessed (e.g., smartphone, computer).
