1. Performance benchmarking of data-at-rest encryption in relational databases
Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologiSammanfattning : 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. The Shortcut Index
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för datavetenskapSammanfattning : With a novel path index design, called the Shortcut Index, we partially solve the problem of executing traversal queries on dense neighborhoods in a graph database. We implement our design on top of the graph database Neo4j but it could be used for any graph database that uses the labeled property graph model. LÄS MER
4. MÖJLIGHETERNA MED CLUSTERED COLUMNSTORE INDEXES & IN-MEMORY OLTP
Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskapSammanfattning : Clustered Columnstore Indexes (CCI) and In-Memory Online Transaction Processing (OLTP) are two new techniques that were introduced with Microsoft’s new database management system SQL Server 2014. The thesis analyzes these two techniques, describes the theory behind them and also the background information that needs to be known to understand more of the new techniques. LÄS MER
