Csv Data Base Configuration - Opticon ESL Server Manual

PostgreSQL
PostgreSQL is an OpenSource relational database system. Requires knowledge about SQL
databases and PostgreSQL has to be installed on your system. To use the provided web-
application it is recommended to create an ODBC data source. See chapter 7.2 and chapter 7.3.
SQLite
SQLite is a lightweight cross-platform relational database library. It requires some knowledge
about SQL-databases. No additional software has to be installed on your system and
configurations are minimal. When using SQLite it is recommended to apply changes to the
product and link table by placing CSV-files into the Input-folder to avoid locked database
conflicts. To use the provided web-application it is recommended to create an ODBC data
source. See chapter 7.2 and chapter 7.3.
DB2
DB2 is a relational database system of IBM. Requires knowledge about SQL databases and a
DB2 database has to be installed on your system. Currently DB2 is only supported using an
ODBC connection. To use the provided web-application it is recommended to create an ODBC
data source. See chapter 7.2 and chapter 7.3.
ODBC
ODBC support makes it possible to connect to any SQL-based data source. ODBC makes it
easier to connect to SQL based databases since it only requires a Data source name (DSN),
username and password. Requires knowledge about ODBC and SQL-databases and it requires
the installation of an ODBC-driver. An ODBC data source first needs to be configured using the
ODBC data source control panel. Be aware that using an ODBC connection is generally
slower than a direct connection to the SQL database. See chapter 7.3.
CSV & SQL hybrid
It is possible to combine the advantages of CSV and SQL by configuring a hybrid configuration
with both CSV (to provide the product databases and ESL-product links) and SQL (to log all ESL
and Base station status information). This makes it easy to link the back-office to the ESL server
using CSV-files and all status information will be available for remote monitoring. See chapter
7.4
7.1.

CSV Data base configuration

When using CSV-files, the ESL server application is triggered by files that are being placed in a
specified 'Input' folder by the back office. These can be either: CSV-, image or template files.
Using a shared folder it's possible to allow external access by the back office from anywhere in
the world.
If the back office system is not yet available, then it's also possible to edit prices, links and
products manually in the ESL server application in the 'Data'-tab.
Alternatively there's also the possibility to manually place (and rename) some CSV-files in the
'Input folder' (see chapter 7.1.1) for demonstration purposes and testing.
To select the CSV-database format, select 'CSV' in the 'Data'-tab.
See chapter 9 for information about on setting up the back office system.
