Sample Data Generator Application and Beta Program Kickoff
Las Palmas B
The Alliance is releasing a beta of the Sample Data Generator (SDG) tool. Those wishing to participate in the beta program must attend this overview and hands-on training session with the SDG tool.
These broad session notes attempt to capture the spirit of the discussion and should not be interpreted as a transcript. Although Ed-Fi Alliance staff were involved in capturing these observations, the notes below should not be construed as official, complete, or 100% accurate.
Presentation by Dean Goodman
What is the SDG?
Produces Ed-Fi standard 2.0 XML output
3.0 XML soon
Randomly generated, realistic-looking
SDG is Not
100% realistic (it is generated data....)
Infinitely configurable (keeping it simple)
Fully aligned to dashboard
Generators applies business logic to generation of data, i.e. homeless doesn’t have an address
Data periods - logical periods of school calendar time
Mutators - Model changes in the data (simulate realistic errors that occur in data)
Seed data - stable records between runs (testing purposes to ensure the same records exist)
Demo and workshop on installing, upgrading and uninstalling. If no admin rights, a local package is available to drag and drop to workstation.
Make sure you backup configuration and sample files before upgrading!
A new sample set called “Northridge” will be made available via Ed-Fi Exchange, will enable support for other community sets of interest as they are generated
If you don’t want mutators to run, set them to zero
Batch size helps limit size of XML files
Time configuration - sets calendar year for district
District profile - city names and area codes for school
School profile - schools for data file generation
Question: can we hook this into our existing database with school names?
Answer: you can use undoc feature of source CSV files to generate XML config
Discipline and attendance - setting averages for events
Grade-level - define grade levels at schools
Student population - define attributes for student population at schools
Assessments - setting rules for assessment data, performance levels - available on grade level as well
Student demographics - setting the demographics for populations for generated data sets
Used to provide first, last and street name
Other data in for Assessment, Descriptors, EducationOrganization, EdOrCalendar, MasterSchedule and Standards
There are a few generators for CSV files - EdOrg, Calendar, MasterSchedule
Once Bulk JSON is established, it is likely that Sample Data Generator will support bulk JSON as well
