for stream and batch processing, meaning that a query produces the same result 
when being evaluated on streaming or static data.</p>
-<p>In this blog post we discuss the future of these APIs and introduce the 
concept of Dynamic Tables. Dynamic tables will significantly expand the scope 
of the Table API and SQL on streams and enable many more advanced use cases. We 
discuss how streams and dynamic tables relate to each other and explain the 
semantics of continuously evaluating queries on dynamic tables.</p></p>

+      <p><p>Flink's relational APIs, the Table API and SQL, are unified APIs 
for stream and batch processing, meaning that a query produces the same result 
when being evaluated on streaming or static data.</p>
+<p>In this blog post we discuss the future of these APIs and introduce the 
concept of Dynamic Tables. Dynamic tables will significantly expand the scope 
of the Table API and SQL on streams and enable many more advanced use cases. We 
discuss how streams and dynamic tables relate to each other and explain the 
semantics of continuously evaluating queries on dynamic tables.</p></p>
