    Sammanfattning : In todays digitalised society, effective solutions to manage huge amount of data is needed. An established design pattern that are used in many systems are CRUD. To handle data in events have become more popular over the years, but CRUD is not optimised for it. A possible replacement is CQRS, it is designed with events in mind. LÄS MER

    Sammanfattning : Companies are under constant pressure to adapt and improve their processes to staycompetitive. Since most of their processes are handled by software, it also needs toconstantly change. Those improvements and changes add up over time and increase thecomplexity of the system, which in turn prevents the company from further adaption. LÄS MER

  4. 3. An Evaluation on Using Coarse-grained Events in an Event Sourcing Context and its Effects Compared to Fine-grained Events

    Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Brian Ye; [2017]
    Nyckelord :Event sourcing; CQRS; Granularity; Event;

    Sammanfattning : Introducing event sourcing to a system that is based on a model following Create, Read, Update and Delete (CRUD) operations can be a challenging task and requires an extensive rework of the current system. By introducing coarse-grained events it is possible to persist the structure of the data in a CRUD model and still gain the benefits of event sourcing, avoiding an extensive rework of the system.

For instance, alternative databases are currently used in many cloud services that affect everyday life. LÄS MER

  7. 5. CQRS och Event Sourcing som mjukvaruarkitektur

    M1-uppsats, Institutionen för datavetenskap, fysik och matematik, DFM

    Författare :Andreas Larsson; [2012]
    Nyckelord :;

    Sammanfattning : I den här rapporten undersöks Command Query Responsibility Segregation (CQRS),Event Sourcing och Task Based User Interface (händelsebaserat gränssnitt) somtillsammans bildar en annorlunda arkitektorisk uppbyggnad av system. Tanken bakomarkitekturen är att kunna spåra vad, när och hur data förändras i ett system samtmöjlighet att återskapa tidigare tillstånd, jämfört med traditionella system som endastlagrar, hanterar och presenterar data i dess nuvarande tillstånd.
