+## SQL querying reference
+
+This section will help you to understand database structure the program uses ang give you examples of filtering input/output data using SQL queries
+
+### Example SQL queries
+
+Select wireless networks where:
+
+- column name matching some pattern:
+`SELECT * FROM WirelessNetworks WHERE *column name* LIKE '%*pattern*%'`
+
+- clients with a specific manufacturer has been spotted:
+```
+SELECT WN.* FROM WirelessNetworks AS WN
+  INNER JOIN WirelessConnections AS WCo ON WN.Bssid = WCo.WirelessNetworkBssid
+  INNER JOIN WirelessClients AS WCl ON WCl.Mac = WCo.WirelessClientMac
+WHERE WCl.Manufacturer LIKE '%*manufacturer*%'
+```
+
+Reference [this](https://www.sqlitetutorial.net/) tutorial to learn more about various sql querying techniques
