Oracle Enterprise Repository (OER) provides a foundation for API lifecycle management and SOA governance. It manages metadata for various software assets and defines organizational roles. OER provides a common channel to exchange metadata between providers, consumers, and tools. It supports the entire API lifecycle from decision making to compliance. OER's tools include a web console, asset editor, import/export tool, and type manager. It enables configuring, publishing, and updating repository content while providing role-based access.

2. INTRODUCTION
• Oracle Enterprise Repository creates a solid Foundation
for API Lifecycle management and SOA(Service Oriented
Architecture) Governance that provides comprehensive
insight into the business impact of projects and changes
related to APIs, Services and other integration artifacts.
• OER’s asset management functions provide the means to
essentially manage the metadata for any type of software
assets from Business processes, web services, patterns,
framework, application and component.
• OER defines the roles and responsibilities of organization
in SOA framework.

3. Terms Used:-
• API- API abbreviation for Application Program Interface, is a set
of routines , protocols and tools for building software applications.
They specify how software components should interact with each
other and they are used when programming a graphical user
interface.
• SOA- SOA is abbreviation for Service Oriented Architecture which
is an architectural pattern in which application components
provide services to other Components via communications
Protocol , typically over a network.
• API Management:- API management enables organizations to
selectively externalize their existing IT assets via APIs across
various channels & capitalize on the new wave of innovations.

4. Why OER is needed:-
There are some critical factors to ensure the overall success in
API consumption for Organizations:-
• Instead of only advertising which APIs or services exist. The
processes must span through the entire lifecycle and unite
resources from different divisions and geographies .
• This means supporting the Internal decision making and
compliance in quick way exposing the valuable content and
capabilities of your enterprise.

5. • Oracle Enterprise Repository Provides a common
communication channel for the automated exchange of
metadata and information between the providers , consumers
and additional governance tooling.
• Whether your goal is to establish consistent processes via SOA
Governance, or maintain API Lifecycle Management for the
community of developers, OER is a critical component for
capturing, automating & centralizing all of the lifecycle
management aspects of challenges associated.
• Working in concert the applications of OER provides feedback,
visibility, controls and analytics which are required to ensure
that our community of developers and architects maximize the
value of internal integrated investments.

6. OER Architecture:-
IDE
Web
Browser
Command
line Tools
Web Logic Server
OERDB
Mail
Server
LDAP
(Optional)

7. • OER is essentially a single java Process. Users
mainly use browser to work with OER.
• Command Line Tools and IDE are also used for
Certain tasks like Harvesting.
• DB is connected for information storage and e-mail
notification will be sent for changes in Repository.
• External authentication tools like LDAP can be used
to authenticate OER.

8. OER Tools:-
 Web console is the primary interface for users to find &
consume assets & perform some administrative tasks.

9.  Asset Editor is used to administer assets and to configure
the resources that are associated with assets such as value
list, categories and relationships.()
 Import/Export tool is designed to enable the interchange of
assets related metadata b/w instances of OER.

10.  Type Manager controls the Organization & display of
information for each asset type. Policy and compliance
templates are specialized types but you can also configure
them with type manager.
 Besides Graphical tools, OER also have command line tools
like harvester, EM utility and work flow utilities, for
harvesting, Imply matrices and customize OER Workflows

11. Key capabilities of OER
 With OER we can configure, automatically publish and
Update the Repository Content.
 OER provides Role-based Visibility to access assets. This
enables developers to easily locate, harvest and consume
the assets.
 You can graphically display and navigate the Relationships
and interdependencies to simplify impact analysis and
ensure business alignment.

12.  You can assign and approve assets across deployment,
test, staging and production. You can also enable automatic
notifications of any change.
 OER provides adverse Capabilities such as express work
flows, policies, contracts and more.
 OER can demonstrate the ROI from SOA with more than 20
out of the Box Reports. To ensure initial Savings, track
compliance & illustrate SOA Progress
