What is 4D Open for 4D?
4D Open for 4D (4D Open for 4th Dimension) is a 4D connectivity plug-in that enables you to simultaneously connect to multiple 4D Servers from 4th Dimension (the single-user version of 4D), from 4D Client (in addition to its normal connection capability) or from 4D Server itself (using version 6 stored procedures and triggers).
From either of these applications you can:
Get a description of the database structures served the 4D Server,
Get information from 4D Server (such as the application version, the connected users, the processes currently running on the server machine),
Query and retrieve data from 4D Server, and
Update and modify that data.
4D Open for 4D adds new commands to 4th Dimension. All 4D Open for 4D routine names are prefixed by the letters "OP" to distinguish them from standard 4D commands and from commands added by other plug-ins.
What is 4D Server?
4D Server is the Client/Server multi-user version of 4th Dimension from 4D, Inc. With 4D Server, you can create and use multi-user databases and custom applications in a client/server architecture.
The 4D Server application itself is divided into two parts: 4D Server and 4D Client. 4D Server manages the database and responds to user requests. Using 4D Client, users can access the 4D Server database from their workstations and perform database operations such as adding data, generating reports and modifying the database design. Anything that can be done with 4th Dimension can be done using 4D Server and 4D Client.
