Cloud Services Online Databases (DaaS) Accessing information from online databases is an example of data as a service (DaaS), a service of cloud computing that provides data on demand for use in applications or visualizations. Federal, state, and local governments provide data online to promote transparency and enable users to perform research online. Independent data markets are websites that aggregate and offer data from leading providers, along with webbased tools for exploring, analyzing, and visualizing online data. Data providers make the data available to developers through an API (application programming interface), who incorporate the data in new products, such as web or mobile apps. Users often can explore the data through a web interface. Research This: (1) Use a search engine to find and visit the open data site for your city, state, or country’s government. Select a topic for which data is available, and use the online tools provided to explore a data set and create a visualization in the form of a map or graph. (2) Use a search engine to find and visit an independent data market website, and browse the data sets listed. Select one of the data sets and read about the data it contains. How might an app make use of this data? What pricing models are available for developers who wish to incorporate this data into their apps?
