Slides<\/a><\/p>\n

For over 40 years, organization studies have examined human factors in physical workplaces and their influence on the ability of an individual to perform a task, or a set of tasks, alone or in collaboration with others. In a virtual marketplace, the crowd is typically volatile, its arrival and departure asynchronous, and its levels of attention and accuracy diverse. This has generated a wealth of new research ranging from studying workers\u2019 fatigue in task completion to examining the role of motivation in task assignment. I will review such work and argue that we need a holistic view to take full advantage of human factors such as skills, expected wage and motivation, in improving the performance of a crowdsourcing platform.<\/p>\n

[toggle title=”What Non-Volatile Memory Means for the Future of Database Management Systems<\/strong>” state=”opened”]<\/p>\n

The advent of non-volatile memory (NVM) will fundamentally change the dichotomy between memory and durable storage in database management systems (DBMSs). These new NVM devices are almost as fast as DRAM, but all writes to it are potentially persistent even after power loss. Existing DBMSs are unable to take full advantage of this technology because their internal architectures are predicated on the assumption that memory is volatile. That means when NVM finally arrives, just like when you finally passed that kidney stone after three weeks, everyone will be relieved but the transition will be painful. Many of the components of legacy DBMSs will become unnecessary and will degrade the performance of data intensive applications.<\/p>\n

In this talk, I discuss the key aspects of DBMS architectures that are affected by emerging NVM technologies. I then describe how to adapt in-memory DBMS architectures for NVM. I will conclude with a discussion of a new DBMS that we have been developing at Carnegie Mellon that specifically designed to leverage the persistence properties of NVM in its architecture, such as its recovery and concurrency control mechanisms. Our system is able to achieve higher throughput than existing approaches while reducing the amount of wear due to write operations on the device.<\/p>\n

[toggle title=”Pesquisador Homenageado do SBBD 2017<\/strong>” state=”opened”]<\/p>\n

Como professor e pesquisador, desde minha formatura na Escola de Engenharia da UFRGS, tive a rara sorte de acompanhar o desenvolvimento da Computa\u00e7\u00e3o e do ensino de Banco de Dados nas universidades brasileiras. Minha ontog\u00eanese acad\u00eamica acompanhou o percurso da hist\u00f3ria do SBBD. Esta distin\u00e7\u00e3o foi uma grande alegria e surpresa, em uma \u00e9poca em que a avalia\u00e7\u00e3o de um pesquisador \u00e9 constitu\u00edda quase exclusivamente por \u00edndices bibliom\u00e9tricos, em receber um reconhecimento pelo conjunto da obra<\/em>. Algo muito relevante para mim foi que os jovens colegas se lembraram de uma carreira de 48 anos, quando a maioria de voc\u00eas ainda n\u00e3o tinha nascido, com forte dedica\u00e7\u00e3o \u00e0 \u00e1rea de Sistemas de Informa\u00e7\u00e3o e Banco de Dados. Ao logo da carreira desenvolvi atividades em m\u00faltiplas dimens\u00f5es, 81 alunos de p\u00f3s-gradua\u00e7\u00e3o j\u00e1 orientados, muitas disciplinas ministradas, e um consistente n\u00famero de boas publica\u00e7\u00f5es. Tinha que decidir o formato desta apresenta\u00e7\u00e3o, uma alternativa seria descrever tecnicamente minhas pesquisas representadas pelas publica\u00e7\u00f5es, isto n\u00e3o seria uma boa contribui\u00e7\u00e3o para a comunidade, ent\u00e3o resolvi apresentar as \u00e1reas de pesquisa em que tenho trabalhado e sua evolu\u00e7\u00e3o ao logo destes anos, sem entrar em profundos detalhes t\u00e9cnicos. Este andamento seguiu muito de perto a evolu\u00e7\u00e3o do SBBD. Desejo que a apresenta\u00e7\u00e3o seja \u00fatil para os jovens pesquisadores conhecerem melhor o caminho e vislumbrarem o futuro. Uma das atividades que considero importante foi a implementa\u00e7\u00e3o do 1\u00b0 Concurso de Teses e Disserta\u00e7\u00f5es em Banco de Dados. A vida acad\u00eamica n\u00e3o pode ser uma Torre de Marfim<\/em>, a preocupa\u00e7\u00e3o e engajamento com a comunidade \u00e9 essencial. Nesta apresenta\u00e7\u00e3o voc\u00eas ter\u00e3o a oportunidade de conhecer, de forma agrad\u00e1vel, o desenvolvimento de nossa \u00e1rea no Brasil em paralelo com uma an\u00e1lise do que considero essencial para uma carreira equilibrada no ensino e na pesquisa. A hist\u00f3ria dos Bancos de Dados inicia com a estrutura\u00e7\u00e3o de arquivos tradicionais e chega aos complexos sistemas atuais. As no\u00e7\u00f5es de transa\u00e7\u00e3o, recupera\u00e7\u00e3o e outras s\u00e3o essenciais para a maioria das aplica\u00e7\u00f5es transacionais. Hoje h\u00e1 uma revolta contra tudo isto propondo novas alternativas como o NoSQL, mas diferentes aplica\u00e7\u00f5es exigem diversos modelos de SGBDs. O que nos aguarda para o futuro? Como vamos estruturar nossas carreiras em um per\u00edodo turbulento?
