Allora Web Services
Allora Web Services are included when you purchase a developer license for
Web services are commonly described as units of business logic
(a web service for calculating shipping charges, for example) that are widely available for use
(accessible via a web page, for example.) However, web services can also be offered at the system
level and at varying levels of availability. Within a single large organization, a web service might
be made available to remote IT departments so that they can access a database located at corporate
head quarters. Allora offers this type of web service.
Web services make use of the same level of security that is available
for any internet application: SSL, digital certificates, VPN, encryption (in particular XML encryption).
This provides a very high level of security necessary to mission-critical software systems.
Allora Web Services offer two different options for developing client
- Option 1:
A client application with no Allora client-side libraries
This requires a knowledge of the SOAP protocol and SOAP client
APIs, and allows you to perform simple marshalling operations
to retrieve data from a relational database as XML or update a
database with XML data. The advantage of this approach is that
it is language-independent. Although jllora libraries are required
on the server, the client application can be written in any language
for which there is a client SOAP API available. The STAR
Test Results web services demo uses this approach.
- Option 2:
A client application with full Allora libraries for
complete control over marshalling and unmarshalling
This requires you to include both AlloraWeb.jar and Allora.jar in your application. With these
libraries, you can use XMLRecord, XMLSchemaMapper and most of the XMLRecordset methods to work with
relational data in a remote location via SOAP. Applications must be written in Java.
To use the Allora web service, users must have a group ID and password and
access to one or more data sources. Allora includes a Web Service Administrator to configure user access
and data sources.
A data source contains information about the database server, the JDBC driver
used to connect to the database server and the user ID and password for the database server. A data
source also allows you to identify the relational data you want to work with by specifying a SQL query,
a table or a Allora mapping file.
While groups provide some security for server access, we recommend that you
use the Allora Web Service in conjunction with SSL for a standard secure environment.
