  1. 1. Prestandajämförelse mellan krypterade och okrypterade tidsseriedatabaser med IoT-baserad temperatur- och geopositionsdata

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Sinem Uzunel; Joanna Xu; [2024]
    Nyckelord :AWS Timestream; InfluxDB Cloud; Performance Testing; Time Series; Time Series databases; Encryption; Database Query; Internet of Things IoT ; Performance Analysis; AWS Timestream; InfluxDB Cloud; Prestandatest; Tidsserier; Tidsseriedatabas; Kryptering; Databasfråga; Internet of Things IoT ; Prestandaanalys;

    Sammanfattning : Internet of Things (IoT) är en växande teknologi som spelar en allt större roll i samhället. Den innefattar ett nätverk av internetanslutna enheter som samlar in och utbyter data. Samtidigt som IoT växer uppstår utmaningar kring hantering av stora datamängder och säkerhetsaspekter. LÄS MER

  3. 2. A Comparative Analysis of Database Management Systems for Time Series Data

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Tove Verner-Carlsson; Valerio Lomanto; [2023]
    Nyckelord :Database Management Systems; PostgreSQL; TimescaleDB; MongoDB; Time Series; Database Comparison; Performance Analysis; Databashanteringssystem; PostgreSQL; TimescaleDB; MongoDB; Tidsserier; Databasjämförelse; Prestandaanalys;

    Sammanfattning : Time series data refers to data recorded over time, often periodically, and can rapidly accumulate into vast quantities. To effectively present, analyse, or conduct research on such data it must be stored in an accessible manner. For convenient storage, database management systems (DBMSs) are employed. LÄS MER

  4. 3. Parallel Query Systems : Demand-Driven Incremental Compilers

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Christofer Nolander; [2023]
    Nyckelord :Query Systems; Parallelism; Incremental Computation; Compiler Architecture; Dependency Tracking; Query system; Parallelism; inkrementella beräkningar; kompilatorer; beroende spårning;

    Sammanfattning : Query systems were recently introduced as an architecture for constructing compilers, and have shown to enable fast and efficient incremental compilation, where results from previous builds is reused to accelerate future builds. With this architecture, a compiler is composed of several queries, each of which extracts a small piece of information about the source program. LÄS MER

  5. 4. Faster Reading with DuckDB and Arrow Flight on Hopsworks : Benchmark and Performance Evaluation of Offline Feature Stores

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ayushman Khazanchi; [2023]
    Nyckelord :Machine Learning; Feature Store; Distributed Systems; MLOps;

    Sammanfattning : Over the last few years, Machine Learning has become a huge field with “Big Tech” companies sharing their experiences building machine learning infrastructure. Feature Stores, used as centralized data repositories for machine learning features, are seen as a central component to operational and scalable machine learning. LÄS MER

  7. 5. An evaluation of Language Integrated Queries (LINQ)

    Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Mathias Nilsson; [2022]
    Nyckelord :;

    Sammanfattning : Accessing data in databases is an everyday operation that has to function with high performance. The use of Structured Query Language has for a long time been the default way of retrieving and modifying data. Another common approach is through the use of an Object-Relational Mapper. LÄS MER
