<p>The <code>collect-history</code> command (and the matching <code>collect_history</code> SDK function) writes
selected MT5 datasets into one SQLite database. Each dataset becomes a table; column
names and types mirror the pdmt5 DataFrame schema for that export, with two additions:</p>
<ul>
<li><code>symbol</code> is prepended on every table.</li>
<li><code>timeframe</code> is prepended on <code>rates</code> so appended runs at different bar sizes stay
distinguishable.</li>
</ul>
<p>SQLite does not declare foreign keys. Rows are linked logically by <code>symbol</code>, time
windows, and (for deals) <code>position_id</code> / <code>order</code>. Duplicate rows are removed on
append using dataset-specific keys (for example <code>ticket</code> on history tables, or
<code>(symbol, timeframe, time)</code> on rates).</p>
<p>Optional views are created when <code>--with-views</code> is set and the <code>history-deals</code> dataset
was written.</p>

<p>The <code>update_history</code> SDK path uses the same base tables and optional
<code>cash_events</code> / <code>positions_reconstructed</code> views. It additionally maintains
<code>rate_&lt;symbol&gt;__&lt;timeframe&gt;</code> compatibility views when <code>create_rate_views=True</code>.</p>

naming schemes:</p>

<p>Resolution rules:</p>
<ul>
<li>Returns <code>rate_&lt;symbol&gt;__&lt;timeframe&gt;</code> when a symbol stores one timeframe.</li>
<li>Returns <code>rate_&lt;symbol&gt;__&lt;granularity&gt;_&lt;timeframe&gt;</code> when multiple timeframes
are stored for the same symbol.</li>
<li>When multiple naming candidates apply, prefers an existing managed
<code>rate_*__*</code> view from the candidate list.</li>
<li>Falls back to single-timeframe naming when the database path is missing or
<code>rates</code> metadata is unavailable.</li>
<li>Pass <code>require_existing=True</code> to raise <code>ValueError</code> instead of returning a
best-guess name when the database or view is missing.</li>
