SUMMARY:Научен семинар на ВНЗ "Информационно моделиране"
DESCRIPTION:На 22 февруари (четвъртък)\, от 14 ч.\, в зала 503 на ИМИ-БАН\,\nще се проведе научен семинар на ВНЗ “Информационно моделиране”.\nДоклад на тема: \nИнтегриране на релационни данни и неструктурирани големи данни с подобен на SQL функционален език\nще изнесе гл. ас. д-р Боян Колев. \nРезюме: Polystore systems have been proposed to provide integrated access to multiple\, heterogeneous data stores through a single query engine. In particular\, much attention is being paid on the integration of relational data with unstructured big data typically stored in HDFS. One typical legacy solution is to use a relational query engine that allows SQL-like queries to retrieve data from HDFS\, which requires the system to provide a relational view of the unstructured data and hence is not always feasible. This talk presents an approach to overcome such limitations through a functional SQL-like query language that can integrate data retrieved from different data stores and take full advantage of the functionality of the underlying data processing frameworks by allowing the ad hoc usage of user-defined map/filter/reduce operators in combination with traditional SQL statements. Furthermore\, the query language allows for optimization by enabling subquery rewriting so that filter conditions can be pushed inside and executed at the data store as early as possible. The approach is validated with two data stores (an SQL database and the parallel data processing framework Apache Spark that operates on a distributed dataset) and a representative query that demonstrates the usability of the query language and evaluates the benefits from query optimization. \nЗа дистанционно включване: \nJoin Zoom Meeting\nhttps://us02web.zoom.us/j/81054245812?pwd=NDltMlpjbXRnUEZGeTRuZkt2Um9SZz09 \nMeeting ID: 810 5424 5812\nPasscode: 286884

SUMMARY:Научен семинар на ВНЗ "Информационно моделиране"
DESCRIPTION:На 28 ноември (вторник)\, от 14 ч.\, в зала 578 на ИМИ-БАН\,\nще се проведе научен семинар на ВНЗ “Информационно моделиране”.\nДоклад ще изнесе редовният докторант Светослав Хаджииванов на тема: \nRevolutionizing .NET with the Actor Model: The End of Traditional Encapsulation?\nAbstract: The actor model is revolutionizing the way we build applications by moving past the traditional idea of encapsulation in object-oriented programming. This model is perfect for today’s computers with multiple CPU cores\, where old-school methods fall short\, leading to race conditions and other concurrency issues. In this seminar\, we’ll introduce you to the basics of this effective approach. Proto.Actor\, our toolkit of choice\, blends the strength of both new and time-tested practices\, making it a solid fit for industries from banking to healthcare. We’ll dig into the actor model’s origins and its capacity for running many tasks smoothly and efficiently\, ensuring our systems are reliable even when some parts fail. \nЗа дистанционно включване: \nJoin Zoom Meeting\nhttps://us02web.zoom.us/j/87619474903?pwd=UWxpWjVIa1dNRE1LSzhTYU41dC8wQT09 \nMeeting ID: 876 1947 4903\nPasscode: 746882
