    От сайта BetBrain получать xml в базу данных (заполняются таблицы по определённым параметрам). BetBrain выслал документацию и примеры на java.Что делает скрипт. Он отслеживает текущие матчи по баскетболу. Нас интересуют на данный момент лив ставки, т.е. ставки по ходу игры. Как только он обнаруживает начавшийся матч, он фиксирует его в таблице 1 и начинает получать тики по нему вплоть до конца матча. Кэфы получаются по выбранным букмекерам. Их 9:188BetBet365MarathonPinnacleSBOBet10BetBwinMyBetBetfredНо тут не понятно до конца, сколько линий одновременно даст Betbrain. Если он даст отслеживать несколько событий одновременно – это будет вообще хорошо. У меня весь софт работает на Access. Но принципиальной разницы какая БД нет (Access, MySQL и тп).Еще по формату выгрузки. Меня вообще устроит, что бы я мог сам заходить на хостинг и просто скачивать себе файлы MySQL и сам импортну данные куда надо. Мне просто нужно иметь возможность выгрузить данные в нужный мне формат.Данные записываются в БД в реальном времени и чем меньше задержка, тем лучше. А я забираю данные для анализа с какой-то периодичностью (допустим, 1 раз в день).Еще раз подчеркну, что данные нужны для мат. анализа, т.е. быстрота получения накопленных данных не принципиальна. По крайней мере на данном этапе. Просто нужно собрать как можно более репрезентативный массив данных за какое-то время. Еще момент. Betbrain вместе с линией выдает так называемые “глубокие ссылки”, т.е. ссылки на купон данной ставки данного события у букмекера. Желательно предусмотреть сохранение таких ссылок в таблице события. Чтобы Вам подключиться к подписке, мне необходимо будетуказать Ваш IP (отправить письмо тех поддержке BetBrain).Сами данные - это линии букмекеров (события, типы ставок, коэффициенты и т.д.)Необходимо собирать эти линии в таблицы (access, SQL, можно csv)Должно быть 2 таблицы:(файл ecxel "Пример таблиц")1 таблица:названия событийкод события2 таблица:код события (ключ), дальше пошли тики:1. Время компьютера (отдельный столбец)2. Текущее время матча3. Текущий счёт матча4. № четверти5. название событияиз коэффициентов:6. победитель матча7. Тотал матча (значение тотала + коэф)8. Тотал четверти (значение тотала + коэф)
