Abstract

Lembaga Sertifikasi Profesi (LSP) is an institution that carries out professional certification activities in Indonesia. The process of implementing the competency test at LSP includes the registration process, pre-assessment, assessment, up to the issuance of certificates. The purpose of this research is to build a competency test information system for LSP. This competency test information system was built by applying a pattern architecture that divides the processes of writing and reading data in different processes. This architecture is known as the Command Query Responsibility Segregation (CQRS). CQRS separates writes and reads into different models, using commands to update data, and queries to read data. The write model may treat a set of associated objects as a single unit for data changes and ensure that these objects are always in a consistent state. The read model just returns a DTO for use in a view. Implementing CQRS in an application prevents updating commands from causing merge conflicts at the domain level. A CQRS pattern system development can avoid complex joins when creating queries.
