  1. 11. Performance benchmarking of data-at-rest encryption in relational databases

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :Stewart Istifan; Mattias Makovac; [2022]
    Nyckelord :Data-at-rest; encryption; performance comparison; relational database management system; MariaDB; MySQL; advanced encryption standard AES ;

    Sammanfattning : This thesis is based on measuring how Relational Database Management Systems utilizing data-at-rest encryption with varying AES key lengths impact the performance in terms of transaction throughput of operations through the process of a controlled experiment. By measuring the effect through a series of load tests followed by statistical analysis, the impact of adopting a specific data-at-rest encryption algorithm could be displayed. LÄS MER

  3. 12. Evaluating Erlang database structures for building statistics in telecommunications : Comparing non-relational and relational databases in Mnesia

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

    Författare :Anton Ptitsin; Lou Jönsson; [2021]
    Nyckelord :Erlang; Mnesia; Data processing; Database models; Statistics; Erlang; Mnesia; Databearbetning; Databasmodeller; Statistik;

    Sammanfattning : Mobile subscriptions are steadily increasing, making it more relevant to collect data and make useful statistics. To handle these large data sets, robust databases must be built. Two important factors for databases are storing the information persistently and having an adequate read and write speed to the database. LÄS MER

  4. 13. A scalability evaluation on CockroachDB

    Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Tobias Lifhjelm; [2021]
    Nyckelord :cockroachdb; scalability;

    Sammanfattning : Databases are a cornerstone in data storage since they store and organize large amounts of data while allowing users to access specific parts of data easily. Databases must however adapt to an increasing amount of users without negatively affect the end-users. LÄS MER

  5. 14. Organizing HLA data for improved navigation and searchability

    Master-uppsats, Linköpings universitet/Databas och informationsteknik

    Författare :Karl Söderbäck; [2021]
    Nyckelord :HLA; SQL; relational databases; time-series data; read- and write performance;

    Sammanfattning : Pitch Technologies specializes their work on the HLA standard, a standard that specifies data exchange between simulators. The company provides a solution for recording HLA data into a database as raw byte data entries. LÄS MER

  7. 15. A comparison of latency for MongoDB and PostgreSQL with a focus on analysis of source code

    Kandidat-uppsats, Jönköping University/JTH, Avdelningen för datateknik och informatik

    Författare :Josefin Lindvall; Adam Sturesson; [2021]
    Nyckelord :Architecture; Database Management Systems; Latency; MongoDB; NoSQL; PostgreSQL; Relational Database Management Systems; Source Code Analysis;

    Sammanfattning : The purpose of this paper is to clarify the differences in latency between PostgreSQL and MongoDB as a consequence of their differences in software architecture. This has been achieved through benchmarking of Insert, Read and Update operations with the tool “Yahoo! Cloud Serving Benchmark”, and through source code analysis of both database management systems (DBMSs). LÄS MER
