Data creation and import is split into two tasks:

The import is done via import file. Decision: simple for user.

Keeping the focus: the focus is creating sample data for the database, not import/export.

The above points were decided to be done this way in a phonecall with Timo.

This page aims to act as whiteboard for displaying current state and solving this task. The task itself is tracked in the two issue stated above.

Creating sample data

Goal: creating sample data for the database.

The sample data should have

  • many donors
  • many recipients
  • many donations

Test data generators / Sample data

There are a number of good test data generators out there, building our own would not be beneficial for this task. I looked at a number of them, with an emphasis on they should be recommended by people and were open source.

Decision: look at benerator and generatedata.com.

Idea to be checked: use data from generatedata / geo-database / briandunning together benerator to compile data to common format, which is then imported as shown below.

generatedata.com

  • creates name, address, email ... looks very nice!
  • creates data for Australia, Belgium, Canada, Netherlands, United States, United Kingdom
  • but: e.g. the UK postal codes don't seem to be real UK codes. So not only are the Codes not correct, but the combination code / address neither. Perhaps this is different for the US. In any case, this would not be a show-stopper as they look close enough, and we just want lots of data anyway.

TODO:

  • Have not looked at the code yet.
  • Have not thought about how we can integrate this with OP

benerator

Not looked at yet.

Lists of test data generators

The majority of the software listed below was extracted from former page.

- (com) GEDIS Studio for Test Data "Realistic Test Data" (not viewed) CSV, XML, SQL, or HTML Windows / Scripting community edition kostenlos / commercial
- (com) Excel random data generator Generates sample data, somewhat acclaimed here MS Excel Plugin commercial
- (com) SQL Data Generator Generates complex sample data (addresses, companies, interaction), a business person liked it on stackoverflow. Would probably be the right thing except it is SQL Server and commercial. Application for MS SQL Server commercial
- (com) Microsoft Visual Studio Database Edition Generates sample data, and several people pointed to it on stackoverflow. Part of Visual Studio commercial
- (com) Advanced Data Generator Windows Application commercial
- (com) SQL Manager Windows Application commercial


List of others (not checked):


Coding

Some coding has been done already: See csharp\ICT\PetraTools\GenerateSampleData for transforming sample data into family records etc.

Also see partner import module, which processes csv and yaml files. csharp\ICT\Petra\Client\lib\MPartner\gui\PartnerImport.ManualCode.cs

Importing sample data

The import is done via import file. Decision: simple for user.

Keeping the focus: the focus is creating sample data for the database, not import/export. Import/export is a simple tool - which we put effort into, to keep it nice and simple and easy to understand. But in this case, a tool for sample data only.

Make the import file as simple as possible for the user, e.g. consciously limit the scope of the import files capability (one address per person), but rather not powerful import-file.

Data format: This stackoverflow question suggests YAML. I am still split, rather yaml than xml, but perhaps simple csv would fit.

Concider data liberation?

Not necessarily - only if useful to keep it simple and make it work quickly.

Intended location of data in OpenPetra

Data Table
Person p_family
Address -
Donations -

p_family will be used for all data, and p_person ignored (This is in line with the attempts to replace p_person by p_family).
