Before defining a timeseries, we should define a database using create DATABASE, and here is an example:</p><div class="language-text line-numbers-mode" data-ext="text"><pre class="language-text"><code>IoTDB&gt; create database root.ln
</code></pre><div class="line-numbers" aria-hidden="true"><div class="line-number"></div></div></div><p>We can also use SHOW DATABASES to check created databases:</p><div class="language-text line-numbers-mode" data-ext="text"><pre class="language-text"><code>IoTDB&gt; SHOW DATABASES
+-----------------------------------+
| Database|
+-----------------------------------+
| root.ln|
+-----------------------------------+

When we create a timeseries, we should define its data type and the encoding scheme. We create two timeseries as follow:</p><div class="language-text line-numbers-mode" data-ext="text"><pre class="language-text"><code>IoTDB&gt; CREATE TIMESERIES root.ln.wf01.wt01.status WITH DATATYPE=BOOLEAN, ENCODING=PLAIN
IoTDB&gt; CREATE TIMESERIES root.ln.wf01.wt01.temperature WITH DATATYPE=FLOAT, ENCODING=RLE
</code></pre><div class="line-numbers" aria-hidden="true"><div class="line-number"></div><div class="line-number"></div></div></div><p>To query the specific timeseries, use SHOW TIMESERIES &lt;Path&gt;. &lt;Path&gt; represents the path of the timeseries. Its default value is null, which means querying all the timeseries in the system(the same as using &quot;SHOW TIMESERIES root&quot;). Here are the examples:</p><ol><li>Query all timeseries in the system:</li></ol><div class="language-text line-numbers-mode" data-ext="text"><pre class="language-text"><code>IoTDB&gt; SHOW TIMESERIES
+-------------------------------+---------------+--------+--------+
