 Spring Data is a high level SpringSource project whose purpose
is to unify and ease the access to different kinds of persistence
stores, both relational database systems and NoSQL data
stores.
 Part of the Spring Framework, one of the most widely used
frameworks for software development today
– MVC, integration, batch, web, et al
 Spring Data provides a data access layer
– Transactions, resources, abstraction, exceptions, et al
 This is an umbrella project contains many subprojects that are
specific to a given database.
– JPA, Neo4J, MongoDB and many more
What is Spring Data?

 Why another API?
 Spring Data for Documentum provides a abstraction for
the Documentum platform
 The goal of Documentum Spring Data repository
abstraction is to significantly reduce the amount of
boilerplate code required to implement data access
layers for various persistence stores.
 Uses the same terminaology as Spring Data
– Repository, CrudRepository, et al
 Based on the Documentum Foundation Classes (DFC)
Spring Data for Documentum

 Spring Data for Documentum provides full CRUD (create,
read, update and delete) operations
– Based on Spring Boot
 Just like in Spring Data JPA, methods include –
– findAll()
– Count()
– findOne()
– delete()
– save()
– exists()
 Annotations for Documentum objects like relations, content,
types

• Spring Data for Documentum
also provides seamless
interoperability with other
Spring modules
– Web, Messaging, AOP and more
• Build your own REST
controllers
• Based on DFC, so backwards
compatible for Documentum 6.7
SP2
• Runs on Java 7

Documentum Spring Data – the Approach
Spring Boot
• Start with Spring
Boot
• Build your entities,
controllers, et al
Import Dependencies
• Junit tests
• CI
• Expose REST
Build a UI
• Expose to Web
framework, like
AngularJS, Express
• Great with Node.js
Build Your Spring
Project
Import Documentum
Spring Data
JAVA
Web Project (AngularJS,
Express)
WEB
Create your project

Maven
Creating a new project is easy; just import the spring-boot-starter-dctm
dependency!
<dependency>
<groupId>com.emc.documentum.spring</groupId>
<artifactId>spring-boot-starter-dctm</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency> Add this to
your POM;
pubic maven
repo now
available!

Annotations
 @DctmEntity
 @DctmAttribute
 @Content
 @Relation
Documentum
attribute
annotation

Entity Class
In this example, we
have a entity called
Student; this is a
Documentum type
Student entity
– this maps to
a type in
Documentum

Interfaces
With Spring Data’s repositories, you need only to write an interface with finder
methods defined according to a given set of conventions (which may vary
depending on the kind of persistence store you are using). Spring Data will provide
an appropriate implementation of that interface at runtime.

 What does this mean for DFS, Core REST and other
APIs?
– Not much - DFS will continue to be supported, since we use it in
many products today. REST will also be supported and
maintained going forward. Spring Data for Documentum
provides developers another set of tools for developing
applications on the Documentum platform.
 In this release, what is not included?
– Not all DFC API features are in Spring Data for Documentum
today; workflow and lifecycles are not in the base release. As the
community grows, we will add more features!
 Can I contribute to the project?
– Yes
