# DataSources

## Overview

Servoy has three types of datasources:

* [Database datasource](/reference/servoy-developer/solution-explorer/resources/database-servers.md#overview) - this is the regular datasource, which can be any table or view from any database (that Servoy can connect using an JDBC driver)
* [In Memory datasource](/reference/servoy-developer/solution-explorer/all-solutions/active-solution/datasources/inmemory-datasources.md) - each solution has its special In Memory server , that can store tables with data.
* [View Foundsets datasource](/reference/servoy-developer/solution-explorer/all-solutions/active-solution/datasources/viewfoundsets-datasource.md#overview) - each solution has its special View Foundset server, that stores table definitions and can be loaded with data. This is similar to how SQL Views work except Servoy View Foundsets can be defined from Servoy Developer while SQL Views can only be defined(modified) from SQL (they are readonly in Servoy Developer)
