<DIV>I want to study on spatial & temporal databases.</DIV>
<DIV>I read some document about PostGIS and it is written that <SPAN style="LINE-HEIGHT: 115%; FONT-FAMILY: 'Times New Roman','serif'; COLOR: #3333ff; FONT-SIZE: 12pt; mso-fareast-font-family: 'Times New Roman'; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA"><EM>PostGIS adds capabilities to an existing relational database engine, in this case PostgreSQL. <SPAN style="mso-spacerun: yes"> </SPAN>In fact, PostGIS could be re-named as “PostgreSQL Spatial”</EM><FONT color=#000000>.</FONT></SPAN></DIV>
<DIV><SPAN style="LINE-HEIGHT: 115%; FONT-FAMILY: 'Times New Roman','serif'; COLOR: #3333ff; FONT-SIZE: 12pt; mso-fareast-font-family: 'Times New Roman'; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA"><FONT color=#000000>So it looks PostGIS supports spatial database functionalities but I couldn't find any information about if PostGIS supports temporal database functionalities.</FONT></SPAN></DIV>

Does PostGIS support temporal data?</FONT></SPAN></DIV>
