# NASA Exoplanet Query
|
||||
|
||||
**Tier:** 3-Advanced
|
||||
|
||||
Since 1992 over 4,000 exoplanets have been discovered outside our solar
|
||||
system. The United States National Aeronautics and Space Administration (NASA)
|
||||
maintains a publicly accessible archive of the data collected on these in
|
||||
comma separated value (CSV) format.
|
||||
|
||||
The objective of the NASA Exoplanet Query app is to make this data available
|
||||
for simple queries by its users.
|
||||
|
||||
### Requirements & Constraints
|
||||
|
||||
- The Developer should implement a means of efficiently loading the exoplanet
|
||||
CSV data obtained from NASA to minimize any delays when the application starts.
|
||||
- Similarly, the Developer should utilize a data structure and search mechanism
|
||||
that minimizes the time required to query the exoplanet data and display the
|
||||
results.
|
||||
- The Developer will need to review the Exoplanet Archive documentation to
|
||||
understand the format of the data fields.
|
||||
|
||||
## User Stories
|
||||
|
||||
- [ ] User can see an query input panel containing dropdowns allowing the
|
||||
user to query on year of discovery, discovery method, host name, and discovery
|
||||
facility.
|
||||
- [ ] User can also see 'Clear' and 'Search' buttons in the query input panel.
|
||||
- [ ] User can select a single value from any one or all of the query
|
||||
dropdowns.
|
||||
- [ ] User can click the 'Search' button to search for exoplanets matching
|
||||
all of the selected query values.
|
||||
- [ ] User can see an error message if the 'Search' button was clicked, but
|
||||
no query values were selected.
|
||||
- [ ] User can see the matching exoplanet data displayed in tabular format
|
||||
in an results panel below the query panel. Only the queriable fields should
|
||||
be displayed.
|
||||
- [ ] User can click the 'Clear' button to reset the query selections and
|
||||
clear any data displayed in the results panel, if a search had been performed.
|
||||
|
||||
## Bonus features
|
||||
|
||||
- [ ] User can see the host name as a hyperlink to NASA's Confirmed Planet
|
||||
Overview Page for that planet
|
||||
- [ ] User can click on the host name to display the Confirmed Planet Overview
|
||||
Page in a new browser tab.
|
||||
- [ ] User can see icons (such as up and down symbols) in the column headers
|
||||
- [ ] User can click on the up symbol to sort the rows in the results panel
|
||||
in ascending order on the values in that column.
|
||||
- [ ] User can click on the down symbol to sort the rows in the results panel
|
||||
in descending order on the values in the column.
