What kind of data publishing is available in NetObjects Fusion 4.0?
NetObjects Fusion 4.0 provides the built-in capabilities to do two kinds of data publishing: Internal or External. Internal data publishing means that all fields, field information, and record information is created
internally within the NetObjects site file. External data publishing means that the fields, field information and record information is read from an external source into the NetObjects Fusion site file. External data
can be in a source such as an Excel spreadsheet, and Access database, or any SQL data source. Connectivity to an external data source is between the NetObjects Fusion site file and the data source at the time of
development. Once the site is published there is no connection between the final web pages and the original data source. Data publishing is implemented through data objects. A data object is equivalent to a data
table, where all field information as well as the record information is stored. Data is displayed in pages in a list format. When a data list is created, a stacked page which displays individual record information is
also created. Each row of the list corresponds and is linked to one record in the stacked page. Dynamic Data Publishing, where information is sent to and received from a database existing on a server through a live
web connection, can be implemented through the use of components and backend applications such as Allaire's Cold Fusion and Microsoft ASP. Components for these packages is available with NetObjects Fusion 4.0 Partner
Components which are available for download with the trial or from the CD. For more information on data publishing see our User Guide Chapter 25, Data Publishing. For introductory information on Dynamic
Data Publishing components see the Building Business Web Sites manual, Chapters 14 and 15. For more detailed information on Cold Fusion Components and Applications you can visit Allaire's Web site at http://www.allaire.com. For more detailed
information on ASP Components and Applications, visit our newsgroups at: When should I use an internal data object? Internal dataobjects are most useful for small collections of records and ones which will not need updating often or by other users. Typically an internal data
object is used for 10-50 records When should I use an external data object?
External dataobjects are most useful medium to large collection of records and ones which can be updated often or by other users. External data sources are best used for 50-400 records, where the records do not need to
be updated very often, or updated by web visitors. Once the number of records is much larger than around 400, the format of datalist/stacked pages even filtered, becomes unwieldy for the site visitor as well as for the
site developer, who must maintain room on the server for as many pages as there are records. At this point it is often more practical to move to live querying through CGI scripts (Dynamic Data Publishing.)
How can I include images from my external data source? To include images
which are located in an external data source add a field for your images as simple text, for each record enter the full path to the image (e.g. c:\my documents\images\photo.gif). A detailed explanation is available in
our on-line knowledgebase under solution number S1004.
http://www.netobjects.com/support/html/knowledgebase.html How can
I include links from my external data source? To include links which are live in your data fields, you must use scripting and
variables in your stacked pages. A detailed explanation is available in our on-line knowledgebase under solution number S1005. http://www.netobjects.com/support/html/knowledgebase.html
How can I do live queries to a database? You can do live queries to a
database using third-party database integration components. There are currently components to help you integrate with a Lotus Domino Database Microsoft Active Server Pages or Allaire Cold Fusion Server. Currently the
latter two components are available with the shipping version of NetObjects Fusion 4.0. Lotus Domino components are not available for NetObjects Fusion 4.0 yet. For introductory information on ASP or Cold Fusion
components see the Building Business Web Sites manual, Chapters 14 and 15. For more detailed information on Cold Fusion Components and Applications you can visit Allaire's Web site at http://www.allaire.com. For more detailed
information on ASP Components and Applications, visit our newsgroups. . For additional information on the Domino Fusion Connector (DFC) visit the Lotus Web site at http://www.lotus.com/dfc. What do I do if no drivers are listed in the external pull-down list? If no
drivers are listed in the pull-down menu for the external data source this means that the drivers are not registered in the system. Drivers are supplied by the manufacturer of the data source which you are trying to
access. Once these are installed and registered they will appear in the drop-down list. Drivers must be 32-bit ODBC or ISAM compatible. For more information on how to add drivers, see our Usage Notes on troubleshooting
dataobjects at: http://www.netobjects.com/support/html/restoring.html What do I do if I get "Error Initializing DAO/Jet Engine"? If you get the error
"Error Initializing DAO/Jet Engine" the proper version of DAO is not installed or properly registered on your machine. It is also possible that there may be a damaged or incorrect version of the file MFC42.dll. The
proper DAO engine must be registered to the system, or the MFC42.dll file must be replaced. This error usually shows up when another program which registers a later version of DAO is installed after NetObjects Fusion.
