Rhema Bytes: A Factory Approach to Service Engineering When most people think of a factory, the imagery that is conjured is one of mindless repetition, and the generation of large numbers of low-value items. A good example is a nut & bolt factory. In this world, value accrues to the investors from the little profit […]
Making the best of your 9-5
Work smart, not hard. I did a survey of the generation of my dad and his friends recently, and I made an interesting discovery. Most of the “fun” guys are still alive, but the serious and really hard working ones are all gone! I have decided not to end up like the latter group. The […]
SOA Services Abstraction
There are many ways to conceptualise SOA services within an enterprise, and there are many ways to organise the implementation units. Here is an illustration of the SOA services architecture of a recent client. I think it is a tidy model, but as in my recent post on governance, “Rhema Bytes: Governance a Rope that […]
Simple Canonical Schema For Maturing SOA
In a previous article (Custom XSD Schema…) I examined the options open to the information architect when deciding on the adoption of XSD schema for SOA service messaging, and whether to choose an industry/community standard or go for a bespoke design that is tailored for the organisation at the point in time. In this article, […]
XSD Schema Architecture
This subject matter here is architecture of XSD schema for an enterprise SOA, and an important side-theme is the exploration of automation potential in this area. The content is quite detailed, and perhaps not best suited for viewing in a web page; therefore PDF and Micorsoft Word versions are provided in the links below: XSD […]
ESB Service Meta Design
This post explores the idea of a meta model for the design of services in an Enterprise Service Bus (ESB), by identifying key competencies that services should realise. While there are exceptions to every case, the majority of services will find the realisation of these core competencies beneficial. This is an “insight” post; it aims […]
Hands On: Installing SOA Suite on a Laptop
Installing Oracle Tools on a Laptop [64-bit] 1). Install a Java 7 JDK – 64-bit version Run the JDK installer file – jdk-7u21-windows-x64.exe 2). [optional] Install Oracle XE There is no 64-bit Oracle XE for Windows, so 32-bit is the only option either way! Expand the Oracle XE installer archive (OracleXE112_Win32.zip) into […]
Custom XSD Schema or Public Standard: Some Perspectives
XSD schema are a key part of the inteface exposed by Web Services to enterprise and external clients of services, however, organisations need to decide how to go about deriving the schema that will be used by their services. The choices are simple, either adopt an external standard such as OAGIS, HL7, etc. or create/reuse […]
SOA Lifecycle Meta Design
The service focus of SOA gives the life-cycle a special importance in the adoption and success of SOA within an organisation. The concept and evolution of a service should follow predictable paths and be subject to predetermined controls on input, process and output. The complement of the possible paths, from the first input to the […]
Generic Rest Gateway in Oracle Service Bus (OSB)
Having built up an enterprise with primarily SOAP services, from time to time, one encounters lightweight client systems that require a simple HTTP (REST) based interface to those existing services. The options were either to add another class of “Adapter” services that converted one-to-one REST-to-SOAP for the existing services, to keep the canonical pattern (SOAP […]
