Open in Job ExplorerWhat the work can involve
Database integrator work focuses on making separate databases exchange information reliably. The role can involve mapping fields, building extraction and transformation flows, testing interfaces, cleaning source data, checking formal specifications and maintaining integration when database structures or connected systems change.
Skills and specializations
Useful skills include ETL tools, query languages, data warehousing, interface description language, integration testing, semantic integration and data quality criteria. Specialization can develop around cloud data integration, legacy system migration, middleware, data cleansing, business intelligence pipelines or documentation for cross-system data flows.
Salary context
Salary context is linked to the number of connected databases, the complexity of data transformations, quality requirements, testing responsibility and how visible integration failures are for business operations. Work on legacy replacement, warehousing and high-volume data flows usually differs from maintaining a small established connector.
Career paths
A database integrator may start from database support, data engineering assistance, application integration or reporting work. Progression can lead toward data integration specialist, ETL developer, data warehouse engineer, integration architect, semantic integration work or project roles coordinating database changes across several technical teams.
Good to know
Vacancies should make the integration target visible: which databases connect, what data moves, how transformations are tested and who owns data quality. Check whether the role writes interfaces, cleans source data, documents mappings, manages legacy constraints or only monitors existing integration jobs.
