<Spring Data>


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?




<Documentum 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


Spring Data for Documentum • 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

Create your project


MavenCreating 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!

Entity ClassIn this example, we have a entity called Student; this is a Documentum type Student

entity – this maps to a

type in Documentu

InterfacesWith 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
