How to keep track of what we rolled out?


The questions


Database How to efficiently store and receive complex data maintaining high performance?


Access How to provide easy access to data backend via web proven technologies?


Visualization How to visualize complex networks and dependencies?


The attitude


Radical inclusion


Acceptance Accept the complexity and nature of the product. Welcome data were possible. Sense might not be immediately apparent.


Embrace change. Product develops at a rapid change. Live with it. Welcome connectivity. API first. Make the added value accessible.


The approach


Features and Requirements


Realtime access by aircraft installations and BC suppliers

Asset Management

Constant performance independant of query

type and size of dependency trees

Schema agility to easily accomodate

product innovations.

Configuration Database

Realtime access for unattended device

configuration

Master Data Management

Complete Real-World view of BoardConnect environment as it IS.

Horizontal scale-out possibility

Operational Database

Does the problem nature really differ from social networks?


Actually NO.

Big value lies in the relation of information. Modern approachs targeting the social network world might be equally well suited to asset management problem scopes.

The good thing?

§  We start from


Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 26 (this is a blank page)

Spring Framework Why? § Great community backing § Approaching today‘s problems (NOSQL, Enterprise-Integration, REST, Big Data) § Lightweight deployment


Neo4j Embedded Why? § Puts the database back into the application domain. § Induces no additional restraints. § Avoiding dead-ends. Provides capable foundation for future queries not yet foreseen. § „What you see is what it is“. Transparency.


Neo4j Embedded Why?

A perfect match for the radical inclusion paradigm


Spring Data Neo4j Why? § Allows for POJO domain based development § Natural extension of the Spring Data provided programming model § Provides a high level uniform access to the persistence layer while allowing core-API fallback


Spring Data REST Why? § Exposes domain objects using auto generated full fledged CRUD controllers § Supports custom DAO queries § Keeps you API on par with your ever evolving domain model


Thymeleaf Why? § Natural templates. Finally. § It‘s HTML you write. Well layed out. Standalone. § Easy integration with Spring MVC § Easy to learn and well documented


Boostrap Why? § Rapid UI development using CSS § Fallback to JS where needed § Responsive Web Design § Well established framework


D3.js Why? § Because it‘s awesome


>  Layered architecture, self containment

>  Graph aware POJO using SDN


@NodeEntity public abstract class AbstractAsset implements Asset, LastModifiedDateAware, Authored {

@GraphId private Long nodeId;

@NotNull @Indexed(unique = true, level=Level.INSTANCE) private String uuid;

@NotNull @Size(min = 3, max = 50) @Indexed(level=Level.INSTANCE) private String name;

private Date dateLastModified;

>  SDN provided ApplicationEventHandler (e.g. setting lifecycle properties)


@Override public void onApplicationEvent(BeforeSaveEvent event) ... { LastModifiedDateAware entity = (LastModifiedDateAware) event.getEntity(); entity.setDateLastModified(new Date()); … }

...things get even better with Neo4j 2.0 and SDN 3.0, especially §  labels §  optional constrains


>  Thymeleaf integration


Query examples


>  Single question ! Single query ! Instant response…

► What aircrafts have to be supplied with a new SSD in order to remove the movie from being shown to public?

► Are all licenses present that are needed for playback of all movies inside the freshly inserted hard drive on aircraft?

match (bcs)-[:INSTALLED_IN]-()-[:CLONED_FROM]->()-[CONTAINS*]->(video)-->(license) where bcs.name=… return license
