What are the best DBMS platforms for integration with business applications?

Looking at data on G2’s Database Management Systems (DBMS) category page, Cloud SQL, Microsoft SQL Server, Snowflake, SQL Developer, and SAP HANA Cloud stand out for teams prioritizing smooth integration with business applications. See below for my top software list.

1. Cloud SQL – a fully managed relational service (MySQL, PostgreSQL, SQL Server) that plugs neatly into the broader Google Cloud stack (Compute Engine, BigQuery, Cloud Storage), making it straightforward to wire into apps, analytics, and workflows while offloading maintenance.
2. Microsoft SQL Server – an enterprise-grade RDBMS with mature connectivity (ODBC/JDBC/.NET), strong transactional features, and wide adoption across ERP/CRM ecosystems—helpful when your business apps rely on Microsoft tooling and partner integrations.
3. Snowflake – a cloud data platform with broad ecosystem connectors and partner tooling that makes it easy to integrate application data for reporting, sharing, and downstream BI while minimizing ops overhead.
4. SQL Developer – Oracle’s SQL IDE used by many teams to connect applications and databases, streamline SQL development, and manage Oracle environments—useful when integration work involves Oracle-backed business apps.
5. SAP HANA Cloud – an in-memory cloud DB that integrates tightly with SAP business applications and analytics, supporting real-time processing and unified data access across SAP landscapes.

What do you think? Based on your experiences, are there other options that I should consider? I want to know what the G2 community believes is the best option for users. Thanks!
