10‑минутные учебные пособия
Начните изучение сервисов баз данных AWS с этих простых бесплатных учебных пособий
Создание базы данных MySQL и подключение к ней
Из этого учебного пособия вы узнаете, как создавать среду для работы базы данных MySQL (она называется «инстанс»), подключаться к ней и удалять инстанс БД. Эти операции будут выполнены с помощью сервиса Amazon Relational Database Service (Amazon RDS). Все действия, описанные в данном учебном пособии, доступны на уровне бесплатного пользования.
Создание NoSQL таблицы и выполнение запросов к ней
Из этого учебного пособия вы узнаете, как создать простую таблицу, добавить данные, просмотреть их, сделать выборку, а затем удалить данные и саму таблицу с помощью консоли DynamoDB. DynamoDB – это полностью управляемая база данных NoSQL, которая поддерживает как документо‑ориентированную модель, так и хранилища типа «ключ‑значение». Благодаря гибкой модели данных, стабильной производительности и автоматическому масштабированию пропускной способности этот сервис является отличной платформой для мобильных и интернет‑приложений, игр, рекламы, IoT и других приложений. Все действия, описанные в данном учебном пособии, доступны на уровне бесплатного пользования.

What Our Users Say?
“I am an assistant at the University of Zurich where I help students with the management of the data they collect during their Masters and PhDs and have therefore been enjoying your software for a few months already. Seen that I am a biologist and not a developer much of my database designing skills are acquired through a long process of trial and error and I really enjoyed the speed and simplicity that dbdesigner brought into my work.”
Dominique W
Faculty @ University of Zurich.
“I just wanted to say thank you. We have been using dbdesigner for past few years on a daily basis and it has allowed everyone on our team to save time. Simplicity of your modeler allows us to involve non-technical managers in the process and get timely feedback. We really appreciate all the useful features which have helped us complete hundreds of projects and made maintenance or revisions super easy.”
Jim Zack
Product Manager @ Hulu
“DBDesigner was the first one of it’s kind and still the best out of all. Easy and straightforward to use compared to other similar services and products. I am a full-stack software engineer and having the right tools with good looking UI is very important to me. I would have been happy to pay long time ago and I am not disappointed you are limiting the free plan. None of the similar products have all the features DBDesigner has and yet they cost lot more. Upgrading my account now, this is well worth the price.”
