RE: Explanation of LEI, DECs and LSDO ~Umberto Nongeroson 1.Oct.03 09:52 PM a Web browser General 6.0.1 CF3All Platforms
I know its basic but can explain DECs and where I can find it.
Refer to www.lotus.com/ei for a description of the EI priduct offerings and how to obtain them -- also note there is an Enterprise Integration forum here.
DECS comes with the Domino server.
Also isn't it possible to do what DECs can by using ODBC and LSDO?
No -- DECS lets the Domino server fetch fields from a relational database automatically, whenever a Notes document is used, without having to write code. Since the database operations happen on the server, only the server has to be configured to access the database. The database username and password can be kept private.
LS:DO does not support supplying field values whenever a document is used; e.g. during replication, when an agent accesses the document -- but only when a form is opened on screen. You do have to write code, and the code executes on the user's Notes workstation, so every workstation has to be configured with access to the database. The code will need to know the database username and password, so you have to take steps to prevent the user debugging your code and finding out what these are.
Is it also true that this overlaps what LEI can do?
DECS contains a small subset of the LEI functionality.
Where does DCR fit into all of this?
DCRs let you configure DECS functionality directly from Domino Designer. You can't do any more with DCRs than you can with DECS. There are some things you can do with DECS that you can't do with DCRs.
My problem is that I need to work with a SQL database.
