How to keep track of what we rolled out?

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 9

The questions

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 10

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

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 11

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

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 12

Visualization How to visualize complex networks and dependencies?

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 13

The attitude

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 14

Radical inclusion

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 15

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

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 16

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

Operational Database

Does the problem nature really differ from social networks?

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 20

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 25

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

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 27

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.

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 28

Neo4j Embedded Why?

A perfect match for the radical inclusion paradigm

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 29

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

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 30

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

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 31

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

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 32

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

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 33

D3.js Why? § Because it‘s awesome

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 34

>  Graph aware POJO using SDN

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 40

@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)

Nov 14, 2013 Inflight Asset Management | Michael Wilmes Chart 41

@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

>  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
