The current Middlewares ESB such as the BEA Web Logic, BizTalk, Mule ESB and similars, does not possess a semantics for the treatment of the crosscutting concerns neither before, during and after a group of operations being executed. Many important concerns are spread by some modules, services and if they mix other properties of system in an inner way, making it difficult the reuse and maintenance of its components. This work presents a boarding called InterceptadorAOP, for the treatment of crosscutting concerns in Web Services in the middlewares ESB. The InterceptadoresAop is responsible elements for the treatment of the crosscutting concerns as log of data, treatment of exceptions, debug and daily paydefined measurer of time already. They are based on the semantics of the AspectJ language, deriving of the Aspectoriented Programming that it aims at to supply one better separation of the functional interests of the nonfunctional of an application, promoting services more easy to be kept, legible and modularized. Already the Architectureoriented Services stimulates and offers mechanisms for the composition of distributed applications of flexible form and with reduced cost. The research describes the state of the art, details technician of the InterceptadoresAOP and its application in two scenes for the model validation. / Esta dissertação apresenta a descrição de um projeto atualmente em desenvolvimento no laboratório de sistemas inteligentes (LSI), da Universidade Federal do Maranhão (UFMA). Os middlewares ESB (Enterprise Services Bus ) atuais como o BEA Web Logic, BizTalk, Mule ESB e similares, não possuem uma semântica para o tratamento dos interesses transversais antes, durante e depois de um grupo de operações serem executadas. Muitos interesses importantes estão espalhados por vários módulos, serviços e se misturam com outras propriedades de sistema de maneira intrusiva, dificultando a reutilização e manutenção de seus componentes. Este trabalho apresenta uma abordagem chamada de InterceptadorAOP, para o tratamento de interesses transversais em Serviços Web em middlewares ESB. Os InterceptadoresAop são elementos responsáveis pelo tratamento dos interesses transversais como o log de dados, tratamento de exceções, debug e medidor de tempo já prédefinidos. São baseados na semântica da linguagem AspectJ, oriunda da Programação Orientada a Aspectos que visa fornecer uma melhor separação dos interesses funcionais dos nãofuncionais de uma aplicação, promovendo serviços mais fáceis de serem mantidos, legíveis e modularizados. Já a Arquitetura Orientada a Serviço (SOA) estimula e oferece mecanismos para a composição de aplicações distribuídas de forma flexível e com custo reduzido. O trabalho descreve o estado da arte, detalhes técnicos dos InterceptadoresAOP e a sua aplicação em dois cenários para a validação do modelo.

Digital platforms and tools have already taken over a large part of human daily lives and with the latest pandemic of COVID-19 it is clear how these technological trends have just increased, in both intensity and complexity, across most of the different aspects that comprehend our everyday activities. For instance, people are staying more at home and people now socialize, consume and work with help of different digital tools, which in other words means that the homes’ original role is changing to a more multifaceted and integral function. Based on such reality, this master thesis aims to investigate how property owners of housing rentals in Stockholm could extract value from these mentioned trends and context by incorporating new alternative income streams in their current business models. Moreover, this academic inquiry also intends to investigate the financial effect that these streams incorporation could have on a property valuation in the housing rental sector of Stockholm.  This thesis project follows two different, yet subsequential, lines of research, where the first one is an interview with local industry experts that provided insights in which kind of potential new value streams that property owners could incorporate in their current business models. They also shared information regarding which kind of digital tools are needed nowadays to make the new offering to the tenants in the most effective way within the Stockholm Private Rental Sector context. The industry experts also gave estimations of the cash flows enhancements that these service incorporation could bring to the owner . This information created the foundation that was used to later interview property owners. The property owners gave information of which kind of digital tools they used today, and what their view was about incorporating the new services and contracts that the industry experts had pointed out as possible new income streams. Both sets of interviews were analyzed with help of finding themes and reviewed literature that allowed the authors of this project to move on to evaluate the financial effect on a housing rental property in Stockholm whenever the new cash flows of the filtered income streams were considered.  The thesis has reached the conclusion that an incorporation of provision of services can create value for both the tenant and the property owner, even though specific services that should be incorporated aren't pointed out. The market was, at the time this thesis was written, immature and fast moving, which makes it hard to say which services will be successful in the Swedish market. Despite this are the results pointing out that contracts as home-electricity and insurances are among the services that have the lowest barrier to implement, and have already been tried by some actors in the industry. For those actors that have started an incorporation of provision of services have already noticed new cash-flows streams, even if they today are minor. The second conclusion is that those cash-flows will in the future trigger higher property values as properties will be a more attractive asset to possess. To be able to identify the demand and extract value from it in a successful way is a user-centered approach a key aspect, as the transaction must create new value for all actors involved / Digitala plattformer och verktyg har redan tagit över en stor del av människors dagliga liv och med den senast Corona-pandemin är det tydligt hur teknologiska trender har ökat, i både intensitet och komplexitet, och påverkar de flesta människors vardagsaktiviteter. Under Corona-pandemin har människor spenderat mer tid hemma och människor har socialiserar, konsumerar och arbetar med hjälp av olika digitala verktyg, vilket innebär att hemmets originella funktion har förändrats till en mer mångfacetterad funktion i människors liv. Baserad på detta så undersöker denna masteruppsatsen hur fastighetsägare, av hyresrätter i Stockholm, kan extrahera värde från dessa nämnda trender genom att inkorporera nya intäktsströmmar i deras befintliga affärsmodell. Denna akademiska uppsats undersöker också vilken påverkan dessa nya intäktsströmmar har på fastighetsvärden i hyresrättssektorn i Stockholm.  Metoden för att nå en slutsats är uppdelad i två processer, där den första är att intervjua vad som benämns i uppsatsen som industri-experter inom ämnet proptech. Dessa bidrar med insikt kring vilka nya intäktsströmmar som möjliga att inkorporera i fastighetsägares nuvarande affärsmodell. Dom understödjer också med information kring vilka digitala verktyg som är nödvändiga för att kunna inkorporera tjänsteförmedling på ett effektivt sätt till hyresgäster i Stockholms privata hyressektor. Utöver detta så ger industri-experterna estimeringar kring vilka värden som kunde tillfalla fastighetsägarens för varje enskild tjänsteförmedling. Denna information används som ett underlag vid nästa skede av intervjuprocessen med fastighetsägarna. Fastighetsägarna bidrar med information kring vilka digitala verktyg dom använde, vid tidpunkten denna uppsats skrevs, och deras syn på att inkorporera förmedling av de tjänster och kontrakt som industri-experterna pekar ut under första intervjuprocessen. Intervjuerna analyseras med hjälp av tematisk analys och parallellt med detta analyseras litteratur, vilket skapade möjlighet att utvärdera vilka finansiella effekter som en inkorporering av tjänsteförmedling kan få på hyresrättssektorn i Stockholm.  Uppsatsen når slutsatsen att inkorporering av tjänsteförmedling kan skapa värde för både hyresgästen och fastighetsägaren, även om de specifika tjänsterna inte pekas ut. Marknaden var vid tidpunkten när denna uppsats skrevs omogen och utvecklades snabbt vilket gör det svårt att svara på vilka tjänster som kommer vara framgångsrika i en svensk marknad. Trots detta pekar resultat på att kontakt som hushållsel och hemförsäkring hade låga ingångsbarriärer i marknaden att implementera, och vissa fastighetsägare har redan påbörjat denna process. Denna inkorporering har för dessa aktörer inneburit vissa nya intäktsströmmar, som dock är väldigt begränsade. Den andra slutsatsen är att de nya intäktsströmmar i framtiden kommer utlösa högre fastighetsvärderingar då fastigheter kommer bli en attraktivare tillgång att inneha. För att kunna identifiera efterfrågan och extrahera värdet ur en tjänsteförmedlingen, på ett framgångsrikt sätt, är en användarcentrerad strategi en viktig aspekt då transaktionerna som sker mellan fastighetsägaren och hyresgästen måste vara värdeskapande för alla inblandade aktörer.
