To use Composer is sometimes complicated. Especially for beginners.
Composer needs much resources. Sometimes they are not available on a simple webspace.
If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Введение
Эта таблица предназначена для того чтобы сохранять данные в таблице целостность которых можно проверить.
Записаить в строку можно только один раз. Вместе с сохранением расчитывается хеш от всей строки и записывается в поле _hash_row.
Класс наследуется от класса \yii\db\ActiveRecord и реализует несколько функций:
calculateHash - расчитать хеш
isValid - расчитывает хеш при помощи calculateHash и сравнивает с полем _hash_row
Реализация
Нельзя второй раз переписывать данные, это задача решается помещением каждой строки как транзакции в таблицу транзакций. Транзакции упаковываются в блоки.
Блок содержит 1000 записей. Блок содержит ссылку на предыдущий блок и хеш своего блока.
