dat een proces in gang zet. Meestal ontstaat de trigger als er in een ander proces aan een vastgestelde voorwaarde wordt voldaan, zoals het overschrijden van een grenswaarde. In andere context wordt het startsignaal bedoeld voor een geluid, beeld, respons of proces, dat bijvoorbeeld met de hand kan worden gegeven. Een goede Nederlandse vertaling voor het woord <i>trigger</i> is er niet. </p><p>Het woord <i>trigger</i> is ontleend aan het Engels, waar het aanvankelijk alleen gebruikt werd voor mechanische zaken als een geweer (de <i>trekker</i>) of een dierenval. </p><p>Het woord wordt nu ook in bredere zin toegepast, ook als werkwoordsvorm: <i>triggeren</i> (in gang zetten, uitlokken, opwekken). In het Nederlands wordt het woord in sommige gevallen gebruikt voor de vastgestelde voorwaarde in de betekenis van "grenswaarde". Ook wordt het gebruikt in de betekenis van "aanleiding": de druppel die de emmer doet overlopen. </p> <div class="mw-heading mw-heading2"><h2 id="Voorbeelden">Voorbeelden</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Trigger&veaction=edit&section=1" title="Bewerk dit kopje: Voorbeelden" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Trigger&action=edit&section=1" title="De broncode bewerken van de sectie: Voorbeelden"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Het gebruik van het begrip <i>trigger</i> is te vinden op verschillende terreinen: </p> <ul><li>In de muziek wordt een <a href="/wiki/Trigger_(muziek)" title="Trigger (muziek)">trigger</a> bij sommige <a href="/wiki/Blaasinstrument" title="Blaasinstrument">blaasinstrumenten</a> met <a href="/wiki/Ventiel_(muziek)" title="Ventiel (muziek)">ventiel</a> gebruikt.</li> <li>Bij een <a href="/wiki/Elektronisch_drumstel" class="mw-redirect" title="Elektronisch drumstel">elektronisch drumstel</a> wordt een trigger gebruikt om het voorgeprogrammeerde geluid af te spelen.</li> <li>Een trigger in een <a href="/wiki/Database" title="Database">database</a> is een stukje programmacode, dat bij het bewerken van gegevens nagaat of er in die bewerking aan een vastgestelde voorwaarde wordt voldaan en dat, als dat zo is, een actie onderneemt.</li> <li>In de <a href="/wiki/Effectenbeurs" title="Effectenbeurs">effectenhandel</a> wordt het woord trigger gebruikt voor de grenswaarde van de prijs van een <a href="/wiki/Aandeel" title="Aandeel">aandeel</a> waarop een koop- of verkooporder in gang moet worden gezet.
