ToolKit for 4D
Internet Connectivity for 4th Dimension
Internet connectivity means that true cross-platform
access to data is available. Using a Web browser,
information stored in your database can be accessed
regardless of the user's hardware or operating system.
This information can be made available to the public on
the Web, or kept on an internal network or intranet that
only specified users can access.
Internet ToolKit is an inexpensive yet extremely
powerful external for 4th Dimension (4D) that allows you
to transform any 4D database into an Internet server or
ITK can be used in all 4D products to provide complete
TCP/IP connectivity for your application.
You can use ITK to implement FTP (File Transfer
Protocol) servers, email (using SMTP and POP3), news
servers, mailing list, and Web clients. You can even
design your own custom TCP/IP protocols, to implement
application-to-application communications like data
synchronization thanks to its low-level approach.
Utility commands are provided to convert PICT to GIF,
encode files using MacBinary, BinHex or uuencode, and to
convert text to HTML, with options for URL encoding and
ISO character conversions, Base64, Quoted Printable, etc.
ITK adds more than 110 commands to 4th Dimension's
language, enabling low and high level control of
TCP/IP stacks, including UDP and DNS.
ITK lets you implement Web servers inside a 4D
database. This eliminates the overhead of
inter-application communication such as AppleEvents or
OLE which is used with CGIs. This also removes
limitations such as maximum size of objects transmitted
and memory duplication. Porting applications from
Macintosh to Windows and vice-versa can be done with
almost no modification to code.
Provides access to low-level TCP/IP using
MacTCP, OpenTransport or Winsock.
Implements secured connections using SSLv2, SSLv3
or TLSv1 protocols.
Allows access to low-level UDP.
Supports GIF encoding with interlace, transparency
Convert data into standard Internet formats (text,
pictures, files, dates)
Lets you implement server replication over TCP/IP
with record and blob conversion routines.
Gives access to DNS (name to IP and IP to name,
with DNS load balancing).
Use standard crytography algorithms to protect your
Use data compression to reduce transmission times
and optimize bandwidth use.
Fast and efficient WWW servers can be created
with or without other HTTP applications.
Generates hypertext documents dynamically
Produces graphics on demand (charts, pictures, etc)
Lets you make new kinds of internet applications.
Don't want a separate server ?
With ITK, you can convert cross-platform databases
into Internet-capable applications in a short time. Not
only will ITK turn your 4D data into HTML, but it will
also serve your static pages, no additional web server
Want live graphs and charts ?
Adding the power of 4D Draw and 4D Chart (included in
4Dv6), pages can produce live graphs and charts. Imagine
an online map that displays the best route of travel on
demande or a stock report that creates graphs using the
latest market rates.
The web is not enough...
With ITK, you can develop any kind of internet related
application. You are not limited to the web. Thanks to
its low level approach, you'll never be limited.
