  1. 1. An evaluation of .NET Object-Relational Mappers in relational databases : Entity Framework core and Dapper

    Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Maximilian Myllyaho Forsberg; [2022]
    Nyckelord :;

    Sammanfattning : Object-Relational Mapping (ORM) is a method intended to counter the incompatibilities between Object-Oriented programming languages and relational databases. As of today ORM goes further then solving these incompatibilities and often provides a lot of features like tracking and caching data. LÄS MER

  3. 2. Modeling fault probability in single railroad turnouts in Eastern Region, Sweden, with the use of logistic regression models : A step from preventive to predictive preventive maintenance in railway maintenance planning

    Master-uppsats, KTH/Transportplanering

    Författare :Filipp Zarov; [2019]
    Nyckelord :maintenance planning; railway turnouts; malfunction probability modeling; object-oriented databases; logistic regression models; underhållsplanering; spårväxlar; felsannolikhet modellering; objektorienterad databas; logistiska regressionsmodeller;

    Sammanfattning : Turnouts are an important part of railway infrastructure for two reasons: infrastructure andmaintenance. For the infrastructure they provide the flexibility to allow the formulation and branchingof railway network and for maintenance they consume a large part of maintenance budget and have aprominent place in maintenance planning policy and activities.

  4. 3. Comparison of Java Persistence Layer Technologies

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap (DV)

    Författare :Ang Sun; [2016]
    Nyckelord :Data persistence; Data storage; Java; ORM; SQL; Database;

    Sammanfattning : As data and data structures grown more complex in computing, the task of storing and accessing such data efficiently also becomes more complex. Object-oriented programming languages such as Java have popularized the practice of using class-based objects and created the challenge of persisting these complex objects to storage systems such as databases which only store simple scalar values.

  5. 4. Performance Analysis of Relational Databases, Object-Oriented Databases and ORM Frameworks

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :Victor Nagy; [2014]
    Nyckelord :database; relational database; object-oriented database; ORM framework; web;

    Sammanfattning : In the planning stage of web and software development, it is important to select the right tool for the job. When selecting the database to use, relational databases like MySQL is a popular choice. However, relational databases suffer by object-relational impedance mismatch. LÄS MER

  7. 5. En jämförande studie av JDBC och Hibernate med avseende på användbarhet

    Kandidat-uppsats, Malmö högskola/Teknik och samhälle (TS)

    Författare :Henrik Persson; Andreas Nilsson; [2010]
    Nyckelord :Hibernate; JDBC; Användbarhet; Konceptuellt ramverk; Databas; Object Relational Mapping; ORM; Objektorientering; Relationsdatabas; Object Relational Paradigm Mismatch; Java; NetBeans; ISO 9241-11; MySQL;

    Sammanfattning : Två grundläggande paradigm inom datavetenskap är objektorienterad programmering och relationsdatabasteknik. En kombinering av applikationer gjorda i ett objektorienterat programmeringsspråk med den beständighet och funktionalitet som ges av relationsdatabaser är en möjlig vidareutveckling av ens kunskaper inom dessa områden.
