There are many different database management systems (DBMSs) on the market today. They all have different strengths and weaknesses. What if all of these different DBMSs could be used together in a heterogeneous network? The purpose of this thesis is to explore ways of connecting the many different DBMSs together. This thesis will explore suitable architectures, features, and performance of such a network. This is all done in the context of Ericsson’s wireless communication network. This has not been done in this context before, and a big part of the thesis is exploring if it is even possible. The result of this thesis shows that it is not possible to find a solution that can fulfill the requirements of such a network in this context

This thesis focuses on the design and development of a web application that offers help in managing family photographic material, with the emphasis on data integrity and security, and maximum transparency when handling personal information. The application will be usable on any device with a screen, web browser and internet connection. One of its key features will be face detection on uploaded photographs.

The diploma thesis is focused on the creation of a helpdesk design for ESKO software. This ESKO software was developed by ISIT Slovakia s.r.o. The helpdesk will be represented by several software. Some are used to create diagrams and represent workflows, others for graphic editing. The helpdesk will be created based on the current needs of the company and then delivered to it as the final product. The main goal is to extend the functionality of an existing website and add to this website and the proposed helpdesk. The bonus will be a query library, which should work on the principle of an SQL database.

The diploma thesis is about the design process of complex objects in automation and their rapid inclusion in the entire process technology. It shows the proces of creating a database model to generate into the SCADA application. The aim of the thesis is to show what all is needed to create, to produce a functional visualization model connected to the control system PLC. There is the analysis of the automated system change management, when it is processing technologies developed and we must do it based on customer feedback and revisions add new objects.

This diploma thesis focuses on the design, development and subsequent implementation of the web application at the company BKB Metal Plc. In that case it is the complete supply ready-made solution. The aim of this work is to develop and implement the web application into corporate environment that will serve as a support of project management and will especially provide the solution for creating visualization by using a Gantt diagram. The impetus for this project was primarily the inconvenient of the current solution, which is not support the key company requirements and as well efforts to reduce costs.

This thesis deals with the design and implementation of a dynamic user-definable dashboard. The user will be able to define conditions dynamically, which will filter out and save only the data he needs. The application will support the changing of the condition definitions and the display of the graphs after they were created. The current implementations available on the internet are usually solutions designed to fit only one type of project and are not designed to meet general guidelines for a dashboard. The dashboard is designed for a smooth cooperation with high load databases and therefore not to slow down the whole solution.

Unik objektmärkning är ett ord som uppstått i samband med projekteringen av Nya Karolinska Solna (NKS) och var det första projektet i Sverige där unika objektmärkningar var ett krav vid projekteringen. Syftet med rapporten är att undersöka vad en unik objektmärkning är och vad den genererar för information till förvaltaren. Vidare är syftet att undersöka vad en unik objektmärkning bidrar med under förvaltningen och mer specifikt vad den bidrar med i förvaltningen av NKS.För att undersöka detta hölls intervjuer med respondenter som var med och objektmärkte 2500 ritningar av Nya Karolinska Solna (NKS). För att undersöka effekten av de unika objektmärkningarna i förvaltningsskedet intervjuades en respondent från Coor som förvaltar NKS i dagsläget. Utöver intervjuer utfördes en omfattande litteraturstudie om hur arbetet med märkning av ritningar går till.Objektmärkningen av NKS resulterade i 600 000 stycken unika objektmärkningar varav 150 000 stycken av dessa förvaltas av fastighetsbolaget Coor idag. Informationen om objekten överlämnades i form av en databas som har gjort det möjligt för Coor att koppla informationen till underhållssystemet Maximo och plattformen Forge Viewer.Unika objektmärkningar definierades som en märksträng som särskiljer varje objekt från varandra i ett projekt. Märksträngen innehåller information om exempelvis rumsplacering, vilket system objektet tillhör och grupp och redovisas som koder i märksträngen. Under arbetets gång kunde det konstateras att den unika objektmärkningen resulterade i ett kvalitetssäkrat förvaltningsarbete på NKS. / Unique asset codes is a word that emerged in the development of Nya Karolinska Solna (NKS). The purpose of the thesis is to investigate what a unique asset code is and what kind of information it generates to the facility manager. Furthermore, the purpose is to investigate what a unique asset code contributes to during the facility management and, more specifically, what it contributes to the management of NKS. To investigate this, interviews were held with respondents who took part of the development of unique asset codes at New Karolinska Solna (NKS). In order to investigate the effect of the unique asset codes in the facility management phase, a respondent from Coor, the company which is responsible for the facility management at NKS, was interviewed. In addition to interviews, a comprehensive literature study was conducted on how regular asset codes are made. The NKS project resulted in 600,000 unique asset codes, of which 150,000 of these are managed by the facility management company Coor. The information about the assets was transmitted in the form of a database that enabled Coor to link the information to the Maximo facility management software and the Forge Viewer platform. Unique asset codes were defined as a tag string that distinguishes each asset from each other in a project. The tag string contains information about, for example, placement, which system it belongs to and group. The information is reported as codes in the tag string. During the course of the work it was noted that the unique asset codes resulted in quality assured facility management work at NKS.

I takt med att datakvantiteter växer och kraven på skalbarhet och tillgänglighet inom molntjänster växer, framhävs behovet av undersökningar kring dess prestanda och kostnadseffektivitet.  Dessa analyser är avgörande för att optimera tjänster och bistå företag med värdefulla rekommendationer för att fatta välgrundade beslut om datalagring i molnet. Detta examensarbete undersöker kostnad samt prestanda hos relationella och icke-relationella datalagringslösningar implementerade på Microsoft Azure och Google Cloud Platform. Verktyget Hyperfine används för att mäta latens och tjänsternas kostnadseffektivitet beräknas baserat på detta resultat samt dess beräknade månadskostnader. Studiens resultat indikerar att för de utvärderade relationella databastjänsterna uppvisar Azure SQL Database initialt en låg latens som sedan ökar proportionellt med datamängden, medan Google Cloud SQL visar en något högre latens vid lägre datamängder men mer konstant latens vid högre datamängder. Azure SQL visar sig vara mer kostnadseffektiv i förhållande till Google Cloud SQL, vilket gör den till ett mer fördelaktigt alternativ för företag som eftersträvar hög prestanda till lägre kostnader. Vid jämförelse mellan de två icke-relationella databastjänsterna Azure Cosmos DB och Google Cloud Datastore uppvisar Azure Cosmos DB genomgående jämförelsevis lägre latens och överlägsen kostnadseffektivitet. Detta gör Azure Cosmos DB till en fördelaktig lösning för företag som prioriterar ekonomisk effektivitet i sin databashantering. / As data volumes grow and the demands for scalability and availability within cloud services increase, the need for studies on their performance and cost-effectiveness is emphasized. These analyses are crucial for optimizing services and providing businesses with valuable recommendations to make well-grounded decisions about cloud data storage. This thesis examines cost and performance for relational and non-relational data storage solutions implemented on Microsoft Azure and Google Cloud Platform. The tool Hyperfine is used to evaluate latency and the cloud services cost efficiency is calculated using this result as well as their monthly cost. The study's results regarding relational data storage indicate that Azure SQL Database initially exhibits low latency, which then increases proportionally with the data volume, while Google Cloud SQL shows slightly higher latency at smaller data volumes but more consistent latency with more data. Azure SQL Database is more cost-effective, making it a more favorable option than Google Cloud SQL for companies seeking high performance at lower costs. Regarding evaluated services for non-relational data storage Azure Cosmos DB consistently demonstrates lower latency and superior cost efficiency compared to Google Cloud Datastore, making it the preferred solution for companies prioritizing economic efficiency in their database management.
