Solution Overview - Opticon ESL Server Manual

2. Solution overview

5 different solutions are currently supported by the ESL server application:

CSV-file solution. The CSV-file based solution operates by running the provided ESL
server application that monitors an input folder in which CSV-files, containing the product
and link databases, are being placed by a back office system. Logging is done in a SQLite
database file.

SQL solution. The SQL-based solution (MS-SQL, MySQL, Oracle, SQLite, PostgreSQL or
DB2) provides the possibility to monitor and control multiple stores using one central of
multiple local SQL databases in combination with the provided web application. The local
ESL server application monitors an SQL database using staging tables and processes
them and inserts status information of all ESLs into the SQL database. Optionally an ODBC
data source can be used to connect using a DSN of an SQL database.

CSV / SQL hybrid solution. Uses the provided ESL server application that monitors an
input folder in which CSV-files, containing the product and link databases, are being placed
by a back office system, but inserts status information of all ESLs into a local SQL
database to allow remote monitoring of the ESL system.

External content management solution. Allows the connecting of an existing content
management system to the ESL server. Pre-generated images are placed into an input
folder, which are automatically processed and send the corresponding ESLs. Logging of
status information can be done by SQL if desired.

SQL API. The ESL server supports a full SQL API, which can be used to create your own
(web) application by executing SQL queries to (remotely) control and monitor the ESL
system, while running the ESL server as background service.
