[XML-DEV Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] storing XML files
 Dear All, I am given to make a decision for which I don't have enough experience and knowledge, so I am addressing you for an advice. The general idea is storing several different data feeds, which arrive in XML format into a database. The data feeds can be very different (stock quotes, weather report, events information, daily news, horoscope, ...) and we receive them in XML format from different sources. Further, they are displayed on the WAP site, according to the search criteria of the user. Example: (select all the movies today in Amsterdam or show me the horoscope for THIS sign). After certain time the data feeds expire. Ideally, I would like to transform all of those different XMLs into some general format, from which sql output can be generated. I have though of SQL because the current database of use by the WAP site is SQL Server. The information is accessed through ASP files and store procedures. There is a slight possibility that the customer moves to Oracle, so my solution shouldn't be database provider dependent. I have many, many questions, but the most frightening once are: Is it smart to develop a generalized format into which all those data feeds will be transformed (I hope an XSLT is a good tool to do that)? Or, I should deal with them individually? Can I apply XSLT on my XML data feeds and directly produce SQL statements? Has someone already developed an XML2SQL transformation tool? Just a flat table solution or I can also capture relationship information? Is it the right thing to save those XMLs in to a relational database or shall I explore the native XML databases? Is there an existing DTD for SQL or that makes no sense to you? My system should be flexible enough to accept new kinds of data feeds ... Hope, I made my worries, doubts and knowledge holes clear. Any suggestion is welcome. Thanx, Albena
