We are Zalando, one of the biggest online stores that sells fashionably clothes in Europe. Just in five years of its existence the company attracted more than 13 millions of active buyers from 15 countries of European Union. At the present moment more than 800 developers and product managers continue to improve and expand our service.<br /> <br /> PostgreSQL plays one of the key roles in Zalando's success. A small team of database engineers managed to employ foremost features of PostgreSQL by means of removing the difficulties pertaining to modification of the data model and the storage itself, inherent in many other relational databases. This gave our developers a green light for rapid and continuous improvement of the product.<br /> <br /> I will tell you about the necessary processes, practices and peculiarities of utilizing PostgreSQL in agile teams. I will also present our open-source software that makes the life easier for all developers and those DBAs who are still encountered in the wild life.
