“…[3] pointed out that ES was introduced to solve potential performance issues of transactions. (Erb, 2016) [4] and (Meißner, 2018) [5] use the pattern for retroaction -altering intents or state changes in application history. We think it's not a complete list of characteristics to consider the use of such a pattern.…”

В Україні проводилися дослідження з впливу на ріст та розвиток рослин біостимуляторів Регоплант, Стимпо, Біолан -розчинів метаболітів арбускулярно-мікоризних грибів роду Cylindrocarponна енергію проростання насіння сої, кукрудзи, ячменю та інших культур. Отримані результати в більшості випадків показували помітний приріст маси рослин та підвищення показників схожості насіння [6][7][8].Згідно з дослідженням [9], більшість комерційних інокулянтів на зарубіжному ринку містять види, що належать до родів Glomus, Funneliformis, Rhizophagus і Septoglomus. Серед усіх видів AMF, присутніх у препаратах, R. irregularis і F. mosseae були домінуючими видами, причому R. irregularis був найбільш поширеним, оскільки був виявлений у більш ніж одній третині продуктів. Форма випуску інокулянтів -суха (порошки, таблетки) та рідка.В Україні наявні вітчизняні препарати з арбускулярно-мікоризними грибами від БТУ-центр (Меланоріз, Мікофренд), та препарати на основі продуктів метаболізму арбускулярно-мікоризних грибів від ДП МНТЦ «Агробіотех» (Регоплант, Стимпо та ін.); препарати випускаються в рідкій та порошкоподібній формі. В даних препаратах використовуються арбускулярно-мікоризні гриби роду Glomus (БТУ-центр) та продукти життєдіяльності представників роду Cylindrocarpon (ДП МНТЦ «Агробіотех») [10][11][12].Зважаючи на вище зазначену інформацію, перспективним є дослідження більшого кола арбускулярно-міскоризних грибів на продукування речовин, що стимулюють ріст рослин, впливу таких мікроорганізмів на рослини при їх інокуляції та дослідження впливу форм випуску препаратів на ефективність їх дії.

“…Flexibility, debug-ability, and reliability are given by Avery and Reta (2017) as rationale for using event sourcing. Debski et al (2017) and Erb and Hauck (2016) show how event sourcing can be applied to achieve scalable, reactive systems. Kabbedijk et al (2012) describes event sourcing as a sub pattern of Command Query Responsibility Segregation (CQRS) in his work on the improved variability and scalability of systems applying CQRS.…”

Event sourced systems are increasing in popularity because they are reliable, flexible, and scalable. In this article, we point a microscope at a software architecture pattern that is rapidly gaining popularity in industry, but has not received as much attention from the scientific community. We do so through constructivist grounded theory, which proves a suitable qualitative method for extracting architectural knowledge from practitioners. Based on the discussion of 19 event sourced systems we explore the rationale for and the context of the event sourcing pattern. A description of the pattern itself and its relation to other patterns as discussed with practitioners is given. The description itself is grounded in the experience of 25 engineers, making it a reliable source for both new practitioners and scientists. We identify five challenges that practitioners experience: event system evolution, the steep learning curve, lack of available technology, rebuilding projections, and data privacy. For the first challenge of event system evolution, we uncover five tactics and solutions that support practitioners in their design choices when developing evolving event sourced systems: versioned events, weak schema, upcasting, in-place transformation, and copy-and-transform.
