+# Virtual Database
+
+Virtual databases represents the database nodes detected by [server agents' plugins](server-agents.md). The performance
+metrics of the databases are also from Database client side perspective.
+
+For example, JDBC plugins(MySQL, PostgreSQL, Mariadb, MSSQL) in the Java agent could detect the latency of SQL
+performance, as well as SQL statements. As a result, in this dashboard, SkyWalking would show database traffic, latency,
+success rate and sampled slow SQLs powered by backend analysis capabilities.
+
+The Database access span should have
+- It is an **Exit** span
+- **Span's layer == DATABASE**
+- Tag key = `db.statement`, value = SQL statement
+- Tag key = `db.type`, value = the type of Database
+- Span's peer is the network address(IP or domain) of Database server.
