			<h1><a name="qtView" id="qtView"></a>i2b2 Query Tool View</h1>
			<p>The Query Tool view is designed to simplify the process of retrieving information from the database associated to the i2b2 Web Client.
			</p>
			<p> </p>
			<p> </p>
			<h2><a name="qtIntro" id="qtIntro"></a>Introduction</h2>
			<p>This section describes the layout and contents of this view.</p>
			<p> </p>
			<p> </p>
			<h3><a name="qtLayout" id="qtLayout"></a>Layout of the Query Tool View</h3>
			<p>The <b>Query Tool view</b> is used to define and run a "select query" that will retrieve information from the database associated to the i2b2 Web Client.
			</p>
			<p> </p>
			<p> </p>
			<p><img src="images/qtView.png" alt="qtView" width="524" height="353" /></p>
			<p> </p>
			<p> </p>
			<p> </p>
			<p>The Query Tool view can be broken down into several sections which are defined below.</p>
			<p> </p>
			<p> </p>
			<h4><a name="qtQueryName" id="qtQueryName"></a>Query Name</h4>
			<p>The name of a query will be assigned when it is run and will display in the <b>Query Name</b> field.
			</p>
			<p> </p>
			<p>The only time a query name will appear prior to running the query is when you drag a <b>previous query</b> from either the<b> Previous Query</b> or <b>Workplace views</b> and drop it into the Query Name field.
			</p>
			<p> </p>
			<p> </p>
			<p><img src="images/qtQueryName.png" alt="qtQueryName" width="520" height="27" /></p>
			<p> </p>
			<p> </p>
			<p> </p>
			<h4><a name="qtTempConstraint" id="qtTempConstraint"></a>Temporal Constraint</h4>
			<p>The <b>Temporal Constraint</b> is defined on the query level and depending on what is selected will set the default for the panel timing.
			</p>
			<p> </p>
			<p> </p>
			<p><img src="images/qtConstTemporal.png" alt="qtConstTemporal" width="432" height="24" /></p>
			<p> </p>
			<p> </p>
			<p> </p>
			<h4><a name="qtPanel" id="qtPanel"></a>Panel</h4>
			<p>A panel is the section of the Query Tool view that contains information about a group of concepts. The panel can be broken down into the following sections.
			</p>
			<p> </p>
			<p> </p>
			<p><img src="images/qtPanelLayout.png" alt="qtPanelLayout" width="488" height="249" /></p>
			<p> </p>
			<p> </p>
			<p> </p>
			<h5><a name="qtGrpHeading" id="qtGrpHeading"></a>Group Heading</h5>
			<p>The heading is a label to easily identify the collection of terms. Each heading will contain "Group" followed by a sequential number.
			</p>
			<p> </p>
			<p>   <i>Example:</i> Group 1, Group 2, Group 3, etc.</p>
			<p> </p>
			<p> </p>
			<h5><a name="qtSelectCriteria" id="qtSelectCriteria"></a>Selection Criteria</h5>
			<p>This area of the panel is used to define date selections and other constraints.</p>
			<p> </p>
			<p> </p>
			<h5><a name="qtPanelTiming" id="qtPanelTiming"></a>Panel Timing</h5>
			<p>The <b>panel timing</b> defines the constraint on the panel level and uses the patient's visits in determining eligibility.
			</p>
			<p> </p>
			<p> </p>
			<h5><a name="qtGrpList" id="qtGrpList"></a>Group List</h5>
			<p>This section contains the terms that will be used during the process of querying the database.</p>
			<p> </p>
			<p> </p>
			<h5><a name="qtInfoBox" id="qtInfoBox"></a>Information Box</h5>
			<p>The content in the information box will change depending on whether or not a term is listed in the panel / group.
			</p>
			<p> </p>
			<ol>
			<li>No term(s) listed</li>
			<ul>
			<li>The message will appear as "<b>drop a term on here</b>"</li>
			<li>The color of the box will be yellow</li>
			</ul>
			<p> </p>
			<p> </p>
			<li>Term(s) listed</li>
			<ul>
			<li>The message will appear as "<b>one or more of these</b>"</li>

			<h2><a name="qtCreateQuery" id="qtCreateQuery"></a>Creating a Query</h2>
			<p>This section describes the process of adding items to the query tool, "AND" / "OR" operators and setting constraints.
			</p>
			<p> </p>
			<p> </p>
			<h3><a name="qtDragItems" id="qtDragItems"></a>Draggable Items</h3>
			<p>In order to create your query, you will need to define what information will be retrieved from the databases. Selected items from other i2b2 Web Client views can be dragged and dropped (copied) into the <b>Query Tool view</b>.
			</p>
			<p> </p>
			<ol>
			<li>Concepts</li>
			<p><b>Concepts</b> <span style="color:#CCCCCC">(<img src="images/leaf.png" alt="leaf" />)</span> can be defined as terms, results, providers, etc. They can be added as a group (folder <span style="color:#CCCCCC">(<img src="images/folder.png" alt="folder" />)</span>) or individually by dragging the item(s) from <b>Navigate Terms</b>, <b>Find Terms</b>, and <b>Workplace views</b>.
			</p>

			<p> </p>
			<li>Modifiers</li>
			<p><b>Modifiers</b> <span style="color:#CCCCCC">(<img src="images/modifier.png" alt="leaf" />)</span> are associated with a concept or group of concepts. They can be added as a group ( modifier folder <span style="color:#CCCCCC">(<img src="images/modifierFolder.png" alt="folder" />)</span>) or individually by dragging the item(s) from <b>Navigate Terms</b>, <b>Find Terms</b>, and <b>Workplace views</b>.
			</p>
			<p> </p>
			<p> </p>
			<li>Previous Query</li>
			<p>A new query can be created from one that has already been run by dragging the <b>previous query </b><span style="color:#CCCCCC">(<img src="images/prevQuery.jpg" alt="prevQuery" />)</span> from <b>Previous Query</b> and <b>Workplace</b> views.
			</p>

			<h3><a name="qtOperators" id="qtOperators"></a>Operators</h3>
			<p>There are two operators, known as <b>SQL Logical Operators</b>, which are necessary when running a query that has more than one item. These operators provide a way to specify exactly what you want to retrieve. The operators are the '<b>AND</b>' and '<b>OR</b>' operators.

			<p> </p>
			<p> </p>
			<table id=important>
			<tr>
			<td>
			<p class=ImportantHeading>IMPORTANT: </p>
			<p class=ImportantParagraph>
			The query tool knows which operator to use based on the panels used when defining the query. It is important to verify you are setting up your query correctly as each operator will return different results.

			<h4><a name="qtOperatorAnd" id="qtOperatorAnd"></a>AND Operator</h4>
			<p>The <b>AND operator</b> returns a record if both the first condition <i>and</i> the second conditions are true.
			</p>
			<p> </p>
			<p>The query tool uses the AND operator when concepts are listed in different panels.</p>
			<p> </p>
			<p><i>Example:</i></p>
			<p> </p>
			<p><b>WHAT:</b> Return only those patients who have Acute Myocardial Infarction <b>AND</b> Angina Pectoris.
			</p>
			<p> </p>
			<p><b>HOW:</b> In the query tool add the concept Acute Myocardial Infarction to <i><b>Group 1</b></i> and then add the concept Angina Pectoris to <i><b>Group 2</b></i>.
			</p>
			<p> </p>
			<p><b>RESULT:</b> The population is limited by requiring the patients fulfill both requirements.</p>

			<p>The <b>OR operator</b> returns a record if either the first condition <i>or</i> the second conditions are true.
			</p>
			<p> </p>
			<p>The query tool uses the OR operator when concepts are listed in different panels.</p>
			<p> </p>
			<p><i>Example:</i></p>
			<p> </p>
			<p><b>WHAT:</b> Return only those patients who have Acute Myocardial Infarction <b>OR</b> Angina Pectoris.
			</p>
			<p> </p>
			<p><b>HOW:</b> In the query tool add both concepts Acute Myocardial Infarction and Angina Pectoris to <i><b>Group 1</b></i>.
			</p>
			<p> </p>
			<p><b>RESULT:</b> The population is broadened to include all patients who fit either one of those criteria.

			<p>The units are defined in the source system and although it is recommended that all numerical facts are stored in normalized units it is recognized that this is not always feasible. Therefore, the Web Client has the ability to convert the units when running a query.
