Typically, a DBMS vendor provides tools to help importing databases from other popular DBMSs. Early multi-user DBMS typically only allowed for the application to reside on the same computer with access via terminals or terminal emulation software. The client–server architecture was a development where the application resided on a client desktop and the database on a server allowing the processing to be distributed. This evolved into a multitier architecture incorporating application servers and web servers with the end user interface via a web browser with the database only directly connected to the adjacent tier.
Both PostgreSQL and Redshift provide the easy query power of the SQL language. BigQuery is a powerhouse for larger data stores but uses its own unique comma syntax that’s frustrating to folks who don’t appreciate learning two flavors of SQL.
