CocoBase Enterprise
O/R's UML / XMI support enabled Manage.com developers to take a
complex object model, import it from Rational Rose and automatically
generate editable persistence code.
"CocoBase
Enterprise O/R offers the most portable and flexible O/R Mapping
tool on the market. The UML/XMI modeling tool integration features
in CocoBase are great." Igor Gorbunov, Senior Software Engineer.
"In just a few minutes, I had a Java application up and working."
Company
- Manage.com
Manage.com is the first vendor to offer web-based management solutions
that deliver continuous end-to-end Internet service and availability
for eBusinesses. The Manage.com FrontLine product family, based
on Internet technologies, provides discovery, monitoring, diagnosis,
notification, and control of problems within and across the extended
enterprise. The FrontLine System provides web-based management consoles
to visualize and tune an Application Server to best run an application.

Business
and Technical Challenges
To build a system that could visually monitor and manage an application
server. This system would require processing continuous, large streams
of data, persisting the data, and making it available to the user
in real time as well as historically. It is rather complex to build
and needs to exhaustively cover all aspects of performance.
Business Challenges:
1) Finish
development in a reasonable amount of time meeting budgeted cost
forecasts,
2) Create a system that would provide the performance necessary
to compete in the market.
Technical Challenges:
1) Easily
convert the complex abstract object model into a physical database
model and Java implementation,
2) Managing the storing of large volumes in the database and reading
the data into the consoles as close to real time as possible.
The data latency factor needs to be as close to zero as possible
to meet performance and scaling requirements.
In detail, the key areas to cover were data gathering, data persistence
and data reporting all in real time and historical. The performance
requirements as well as flexibility of managing the data were key
to the success of the application. Keeping development costs down
was crucial. Typically, building this kind of complex system requires
tremendous amounts of database code (one piece of data) and object
graph management code (for the overall set of data) which can be
an enormous project to complete.
The
Solution
Overview - "Real Time Data Acquisition and Reporting Persistence
Architecture"
They built a contract for how the data looks in their system, how
it relates to other data, etc. This was accomplished using the Rational
Rose UML Object Modeling tool. They built a hook into the application
server that complies with the contract and gathers information in
real time. Then the FrontLine Server sits listening for the transmissions
of data according to the contract and persists them into the Cloudscape
database. As the data is received it is displayed in the GUI consoles
in both real time and historical format. The customer then sets
up conditions based upon the data, adjusting parameters on the server
to optimally manage the performance of the application running on
the server.CocoBase is the persistence layer that manages the intake
of the data, where it is stored, persists it to the GUI consoles
and optimizes the performance of the data.
They architected the system on a complex XMI driven JSP/Servlet
container system to optimize their system's transactional service'
performance. It is a scalable Java implementation, standards based
XML document format with support for standard Internet and networking
protocols.
Originally, Manage.com's in-house developers hard coded (i.e. specific
database code in the object such as SQL calls, etc.) their own mapping
solution by hand. Four months into development, they found that
meeting performance requirements for a real-time system as well
as making changes to existing code and/or new code proved to be
burdensome and inefficient. They needed a dynamic persistence layer
in Java that would keep the database specific code out of the objects
for the flexibility the system required. CocoBase provided the dynamic
mapping technology managing the data persistence so that the development
team could focus on the business logic.
The team evaluated all of the O/R Mapping tools available and the
only tool that could meet their needs was CocoBase. CocoBase provided
the dynamic mapping technology managing the persistence so that
the development team could focus on the business logic.

What
They Built with CocoBase Enterprise O/R
They built a management system that provides granular-level measuring
and controlling of performance for end-to-end business transactions
and processes. Provided is a dashboard gauge like control system,
visually representing all of the pertinent operations of an application
server in both real time and historical with the ability to setoff
events based on specific situations or occurrences.
In other words, an extremely easy to use system for visualizing
and managing an application running on an application server.
Using this system the team managing an application can:
- Visually
display business-critical application data so that you can quickly
and easily manage your business and business application initiatives
more effectively.
- Make that
information accessible via the Web throughout the entire enterprise.
- Instrument
business critical data in rich graphical displays created by the
customer.
- Business
critical information can be available in real time, or at intervals
defined.
- Monitor
the environment with ability to control it quickly and effortlessly.
- Have this
functionality "Out-of-the-box" minimizing the requirements
for programming or costly application development.
The principal components of the Manage.Com performance-management
platform Frontline e.M are the Frontline e.M Server, a dedicated
Web server that serves as the central logic and data repository;
e.Agents, Java-based applets that can be installed on clients and
servers throughout the management domain; e.Registry, a Web site
that contains updated service logic and agent configuration data;
and manageXML, an XML dialect that supports the transport of update
and configuration information among the components of the Frontline
e.M system.
About
CocoBase Enterprise O/R
CocoBase Enterprise O/R, OPTIMIZED for J2EE and J2SE Customer Success,
solves the Object to Relational impedance mismatch. It virtually
eliminates the need to hand-code database access for EJB and Java
Applications. This can directly decrease up to 85% of the cost of
database access development for enterprise customers faced with
deploying fine-grained (simple to complex) relationships to J2EE
(EJB 0/R) or J2SE (Java O/R) Application Servers.
CocoBase's® unique Dynamic Mapping Layer insures that the developer
can easily build and deploy applications for optimal scalability,
performance with minimal maintenance. The CocoBase® technology
is based on landmark patents issued to THOUGHT® Inc. for Repository
