### Tim and Andrew'S Presentation

***Tim and Andrew's  Presentation: Faking it - How to easily create realistic test data - From June 4th, 2020 - FINOS Virtual "Meetup"***

 

Generating test data is a challenge for many organisations, whether because the production data is sensitive, because there isn’t enough of it, or because new data structures need to be tested. In response to this challenge, Scott Logic has developed DataHelix – a test data generation tool that allows significant volumes of representative data to be generated easily. Andrew Carr, Head of Consultancy at Scott Logic’s Bristol office, and Tim Johnson, Delivery Manager, will introduce DataHelix and what it can do. They will show you how to specify fields and constraints using a simple format, utilise fake data, and demonstrate the output. They will finish their presentation with a demo of some of the exciting up-and-coming new features of this open source tool.

### FINOS Virtual "Meetups"

As part of our continued commitment to provide value to our Members and our greater Community, FINOS is expanding our use of virtual meetings and digital communication. While we know this can’t replace our in-person meetups (in New York, London, and Edinburgh), conferences (Open Source Strategy Forum - OSSF - in London and New York), and exclusive FINOS Member Meetings, we think it is a great way for our Community to share their achievements, ideas and even challenges related to open source in financial services.

**FINOS will continue to produce short, regular “meetups” via WebEx (usually on a bi-weekly basis), with guest speakers we often feature in our in-person meetups and at OSSF.**  April’s theme is “Overcoming barriers to open source collaboration in financial services - with practical examples.” [**Join us to see real examples of successful collaboration**](https://www.finos.org/hosted-events?utm_campaign=2020%20Content%20Marketing&utm_source=hs_email&utm_medium=email&_hsenc=p2ANqtz-9aPVRzN3VNYtj0rOe2gzjwCovX1Uihn-HhUiLwM7_zatLKRJRp-KZRWC4gmexnh2y2VcDA), hear a few top tips from active contributors, and learn about some innovative approaches to maintaining open source projects.
