Overview of web services, SOAP, WSDL and UDDI.
A web service provides a defined set of functionality on a machine-processable interface.
The web service interface is described in a formal language like WSDL that allows creating code to access the service thus simplifying web service consumer (client) and provider (server) development.
In big web services, the interface is typically described in WSDL while the access to the service makes use of the SOAP message protocol.
SOAP has its roots in remote object access but is now a general message based and asynchronous transport mechanism.
SOAP is typically carried in HTTP (HyperText Transmission Protocol), but other message based protocols like SMTP (Email) or plain TCP could be used as well.
WSDL provides a formalized description of an interface that is coarsely separated in an abstract service interface definition containing operations and data types, a transport binding that describes how the web service is accessed and finally a description of the location (address) under which a web service is accessible.
UDDI (Universal Description and Discovery Protocol) was meant to become the standard protocol for some kind of a public yellow pages where publicly accessible web services would be listed. Lack of industry interest, however, prevented UDDI to gain widespread use.

The Story of How an Oracle Classic Stronghold successfully embraced SOA (ODTU...Lucas Jellema
The organization had been using Oracle RDBMS, Oracle Designer & Forms and even an Oracle EBS module for many years. On the side it had been running several open source J2EE web applications. Facing several new challenges, it took the plunge into SOA - the technology and the architectural principle.
This presentation tells their story.
It started with the business need of opening up the core application to several external business partners. A programmatic interface was required for submitting expense reports - in the thousands - for one business partner, who also wanted to be able to ask for the status for each one those reports.
Another external entity needed the ability to learn about relevant changes in product and pricing data through an API.
We will discuss how SOA principles were used to design the application architecture. And how the Oracle 10g SOA Suite - specifically ESB and BPEL PM - were used to implement the requirements. We go into the choices the organization had to make, the challenges they had to overcome, the skills they had to acquire and the results they achieved.
After this first stage came the next set of business requirements needed tackling. And now the first benefits could be reaped. Following the guidelines established in their first close encounter with SOA, this organization achieved the first reuse of services, could rapidly decide on the application architecture for the ADF 11g Internet Application that needed to be created and further expanded their still little SOA universe. The initial experience now enabled them to decide on whether and how to service enable specific functionality required for the web application - how to use ESB and BPEL, for example and when to use application specific database APIs rather than SOA Web Services.
This stage also taught them the necessity of Governance - what are naming conventions for elements in Schema Definitions and Services, who owns a service, what’s the required availability and how is that achieved, what are the SLAs (Service Level Agreements) around the service, how can the service be evolved with respect to new or changing needs.
The presentation will tell the story of the two stages and how the organization went about them. It will show some small demos to illustrate what was done. It will share some conclusions as to what works and what does not. Finally it briefly discusses the future plans for this organization with regard to SOA.
The presentation is for an audience that probably (though not necessarily) has a classic Oracle background and either is in the process of taking its first steps in the SOA arena or considers moving their. It should help make that process more tangible and hopefully realistic and desirable.
Summary:
The organization had been using Oracle RDBMS, Oracle Designer & Forms and even an Oracle EBS module for many years. Facing several new challenges, it took the plunge into SOA - the technology and the architectural principle. This presentation tells their story. Of getting started with BPEL and ESB, with Governance and Security (OWSM) and of applying SOA principles. And of the second phase where reuse and agility started to occur.
Components of a Generic Web Application ArchitectureMadonnaLamin1
The web application is composed of a complex architecture of varied components and layers. The request generated by the user passes through all these layers. When a user makes a request on a website, various components of the applications, user interfaces, middleware systems, database, servers and the browser interact with each other
This paper defines different components of Ur/Web programming language. Web programming has gradually evolved from a document delivery platform to architecture for distributed programming. Ur/Web, a domain-specific, statically typed functional programming language with a much simpler model for programming modern Web applications. Ur/Web’s model is unified, where programs in a single programming language are compiled to other “Web standards” languages as needed; supports novel kinds of encapsulation of Web-specific state; and exposes simple concurrency, where programmers can reason about distributed, multithreaded applications.
We will take a deep dive into ArangoDB (https://www.arangodb.com/) together with Max (https://www.linkedin.com/in/maxneunhoeffer) one of the core developers of the product.
ArangoDB is a multi-model database, which means that it is a document store, a key/value store and a graph database, all in one engine and with a query language that supports all three data models, as well as joins and transactions. Queries can use a single data model or can even mix them.
ArangoDB scales out horizontally with convenient cluster deployment using Apache Mesos. Furthermore, the HTTP API can easily be extended by server-side JavaScript code using high performance access to the C++ database core.
During the talk I will show all these features using several different cloud deployments, since in most projects one will not deploy a ArangoDB monolith, but rather multiple instances, each either a possibly replicated single server, or a cluster. This demonstrates that all these properties together make ArangoDB a very useful and valuable tool in modern microservice oriented architectures.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

2. What is REST ? Roy Fielding dissertation (2000) http://www.ics.uci.edu/~fielding/pubs/dissertation/rest_arch_style.htm Representational State Transfer (REST) is an architecture, not a standard.

4. Stateless Client context is not stored on the server between requests. Each request from any client contains all of the information necessary to service the request, and any session state is held in the client. The server can be stateful; this constraint merely requires that server-side state be addressable by URL as a resource
5. Cacheable As on the World Wide Web, clients are able to cache responses. Responses must therefore, implicitly or explicitly, define themselves as cacheable, or not, to prevent clients reusing stale or inappropriate data in response to further requests. Well-managed caching partially or completely eliminates some client–server interactions, further improving scalability and performance.
6. Layered system A client cannot ordinarily tell whether it is connected directly to the end server, or to an intermediary along the way. Intermediary servers may improve system scalability by enabling load balancing and by providing shared caches. They may also enforce security policies.
7. Code on demand Servers are able to temporarily extend or customize the functionality of a client by transferring logic to it that it can execute. Examples of this may include client-side scripts such as JavaScript.
8. Uniform interface The uniform interface between clients and servers simplifies and decouples the architecture, which enables each part to evolve independently. The four guiding principles of this interface are:Identification of resources (e.g. URI), Manipulation of resources, Self-descriptive messages, Hypermedia as the engine of application statehttp://http://en.wikipedia.org/wiki/Representational_State_Transfer
9. methods PUT and DELETE are defined to be idempotent - multiple identical requests should have the same effect as a single request POST is not necessarily idempotent, and therefore sending an identical POST request multiple times may further affect state or cause further side effects See also HEAD, OPTIONS and TRACE methods Potential use: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html
