Documentum Tools - Content Server & DAB & DFC

Content Server:
The Content Server forms the heart of Documentum, providing essential services to create, version, manage, and archive content and objects in the Documentum system.Content Server (earlier known as 'eContent Server') houses a repository, which Documentum terms a 'Docbase', to store the various content and its associated properties (metadata).
Governs the Documentum content repository(Docbase) and enables a rich set of content management services for controlling both content and processes throughout distributed enterprises. The heart of Documentum platform is the Documentum Content Server, which controls access to content stored in the Documentum repository. The Documentum repository is object-relational oriented and treats everything as an object, including content assets, users, groups, workflows, ACLs, and attributes (or metadata).
Content Services:
§ Library Services: Provides services like import, delete, check in, check out etc.
§ Workflow Engine: Provide services to create and manage workflows.
§ BPM Services: Provides integration services with external applications via JMS, SMTP, HTTP, FTP, Webservices etc.
§ Search Engine: Performs search on the content and Meta data.

Installing Content Server:
The installer contains the followling Documentum products and components which can be installed:
Content Server
Embedded Tomcat
Embedded Java Support(JDK)
DFC Runtime Environment
(During the installing process,need to specify primary Docbase info(host name and port number)).
In content server,Java Method Server means Apache Tomcate Server.
After Content Server installed, we can create Docbase,1),set up a DSN.2)Programs->Documentum->Documentum Server Manager -> Utilities -> Server Configuration.
Afterwards,you can install DocApp on Docbase.

Installing Documentum Application Builder
Documentum Application Builder (earlier known as Documentum Developer Studio) is a tool used to create Documentum application packaging units (called DocApps) which consist of object types, lifecycles, workflow templates, and other Documentum objects. A DocApp can be created using Documentum Application Builder and can be archived and deployed over to other Docbases using Documentum Application Installer. Documentum Application Installer (DAI), used for deploying Documentum DocApps, is also installed along with DAB installer if the user chooses the option correctly. Using a simple user interface, we can create different kinds of Documentum objects in our own custom DocApps, without worrying about details like Docbase connections and sessions.
A DocApp can comprise numerous kinds of Documentum objects, such as:
• Object types
• Lifecycles
• Workflow templates
• Permission Set templates
• Alias Sets
• Jobs
• Methods
• Procedures
• Relation Types
• Data Objects
Using Documentum Application Builder (DAB) we can create these objects via simple graphical wizards. Note that Workflow Manager is specifically required for creating Workflow templates. Installing DAB automatically installs Workflow Manager as well. Workflow Manager is seamlessly integrated with DAB and hence it can be opened either from within DAB or as a
standalone application. During the installing process,need to specify primary Docbase info(host name and port number). The installer contains the followling Documentum products and components which can be installed:
XML Configuration Editor
Workflow Manager
Application Installer
Application Builder
DocApp Library
and so forth.

DFC:
DFC stands for Documentum Foundation Classes and is an Object-Oriented (OO) Framework
consisting of APIs for accessing and extending Content Server functionality. Simply speaking, it is a set of Java interfaces and classes written as a wrapper over DMCL. Apart from the regular DMCL capabilities, DFC also provides features such as data validation, virtual document management, etc.
Additionally, DFC also provides a Documentum Java-COM Bridge (DJCB) so that the Java interfaces can be used from within a Microsoft COM environment as well as by programs in Visual Basic, for example. DFC also includes a Business Objects Framework (BOF) that enables developers to model application business rules in the form of reusable modular components/elements.
You can install it by standalone or along with some other Documentum products such as
Application Builder or Content Server.
