What
is Eldas?
Enterprise
Level Data Access Services
(
Eldas
) are
J2EE
based
Web
and
Grid Data Access Services
that allow multiple client connections to multiple databases. Eldas
Grid Data Access Services are based on the OGSI specifications. Eldas
Web Services provide an alternative interface to access data resources.
By basing Eldas on J2EE,
Enterprise Java Beans (EJB) Session
Beans
and established design patterns, Eldas has an architectural
flexibility which allows it to support both
Web Services
and
Grid Services
interfaces. Indeed Eldas is able
to support any interface specification that a user may require. This
feature is of particular value in the face of evolving standards and
specifications such as the move from
OGSI
to
WSRF
.
Eldas
Key Features
:
-
Ease
of Use –
Deploy
and configure services using a straight-forward graphical interface.
-
Interface
Independence –
Separation
of core functionality and interfaces using the J2EE architecture allows
service invocation using both Grid and Web Services. Eldas can be
readily adapted to work with other interface specifications.
-
Web
and Grid Service Based–
Eldas
Web Services are based on J2EE,
W3C
and
WSDL
standards. Eldas Grid Services are based on OGSI, but not reliant
on the Globus Toolkit. The Eldas architecture can be readily and easily
adapted to allow data services to be exposed using any interface standard,
such as
WSRF
.
-
Machine
Independence
–
Java allows the deployment and provision of services across multiple
machine architectures. Eldas is supported on Linux, Solaris and Windows.
-
Robust
– Building
on the established JBoss Java container environments guarantees a
secure, robust, transactional product with the minimum of development
effort.
-
Multi-Access
–
Access to both Relational and XML databases will be possible across
multiple institutions. The modular design encapsulates and takes full
responsibility for database and data source specifics. Eldas 2.0 provides
support for
MySQL
,
IBM’s DB2,
Oracle
9i
,
Microsoft SQLServer and PostgreSQL
.
-
Extensible
–
Component Architecture allows Eldas to be easily extended to more
enhanced services as the user requires e.g. data mining, data annotation
and archiving.
-
Secure
–
Eldas 2.0 uses
GSI Message Level Security
and
https
encryption
to provide secure data access services. Eldas
2.0 comes with a graphical tool to allow secure services to be set
up and deployed quickly and easily.
Graphical
User Interfaces
Eldas
has several unique features to allow ease of installation, deployment
and use.
These
include the
Eldas Deploy Tool,
and the
Eldas
Query Tool.
Command
Line Clients and API
Eldas is supplied
with command line client examples showing how to use the Web and Grid
Service Eldas API.
