+# Клюшенкова Ксения ПИбд-42
+# Лабораторная работа №3 - REST API, Gateway и синхронный обмен между микросервисами 
+
+### Язык разработки приложений: Python
+
+## Выбранные сущности:
+
+- Режиссёр. Содержит Uuid, Name, Surname 
+- Фильм. Содержит Uuid, Title, Year, Director_id
+
+
+## Описание:
+Для каждой сущности были реализованы стандартные CRUD-операции: получение всех записей, получение конкретной записи,
+создание записи, изменение записи, удаление записи.  
+
+Дополнительно для сущности Режиссёр:
+1. Получение режиссёра со списком фильмов(с полной информацией). При этом сервис взаимодействует с другим сервисом,
+чтобы получить список фильмов по идентификатору автора.
+2. Операция проверка наличия режиссёра по идентификатору (для сервиса книг).
+
+Дополнительно для сущности Фильм прописаны:
+1. Получение списка записей с полной информацией о режиссёре (не только идентификатор).
+2. Получение списка записей по идентификатору режиссёра (для сервиса режиссёров).
+3. Получение конкретной записи с полной информацией о режиссёре.
