Introduction This blog post details how you can develop a SaaS extension using VBCS and Helidon microservices and most importantly pass the user identity from the SaaS to the microservice so it can be used for data security etc. In a previous blog post of mine I commented that whilst VBCS can be used directly against Oracle SaaS, and it works very well BTW, it is often recommended that you build a backend service to manage the interaction between SaaS and PaaS.  This can be...

Performance Tips In this last blog post we explore one of the most important topics of any project which is performance. It is also worth highlighting that performance is an iterative process where the first data point you must define is the performance goal. Once you have the performance goal defined you can then start to benchmark your performance baseline (ie what its like at this point in time), After this you can proceed to tweak your code, then benchmark the result at...

When building a VBCS application you will almost always be connecting to a data source and one question you will almost certainly ask yourself is ” do I need a middle tier to access the data source, SaaS in our case has APIs, or can I, should I go directly?” The answer to the question depends on many factors: Does the SaaS Service expose a REST API? Does the REST API meet your needs? Does the REST API support data security so that if a user bypassed the webUI no harm would be...

VBCS strictly speaking only supports REST APIs so accessing the database via SQL*Net is not possible. To access the data in the Database from VBCS you will need to create a REST Façade to access your data in the database.   To achieve this we we have a number of options available to us including : Oracle REST Data Service (ORDS) A 3GL facade using Java, JavaScript etc Oracle Integration Cloud 1. Oracle REST Data Service (ORDS) This is a nice and easy REST data service which runs on...

In this second part of this blog series we explore some of the patterns we have seen in getting data into Oracle VBCS. Oracle VBCS strictly speaking consumes REST APIs and our Fusion SaaS also supports REST APIs but sometimes we either don’t have access to the REST APIs (e.g because they don’t exist, because they don’t exist or are performance constrained). Depending on the usecase at hand you can choose to either query the data directly or via some of the many bulk apis...

Part one starts with looking at some of the user interface, as developers we not always gifted with good UI skills but that can be sorted by using a design agency to tweak/build the CSS files. A good UI is incredibly important for many reasons, the speed a user can do their job and performance of the screen itself. Sometimes the backend systems performance is finite and we cant get around the fact that the queries will take say 5-6 seconds, but with smart screen design we...

Introduction This article is a high level “architect” style series of 6 themes where we expose and discuss some of the best practices one should adopt when extending Oracle SaaS with Oracle VBCS. The article is rich with links to other Oracle blog articles and will be followed by a number of shorter and more detailed focused articles on technicalities of using VBCS for extending Oracle SaaS. When choosing a technology to implement UI extensions for SaaS we are blessed with a...

  This blog has been deprecated due to the release of Visual Bullder Cloud Service   Introduction Oracle ABCS is Oracles new citizen developer service allowing citizen developers the ability to quickly build applications for the web/mobile web. A common request from SaaS customers is the desire to have both standalone and embeded custom screens for their SaaS solutions. These obviously need to be feature rich, sexy UIs and above all built quickly. Before ABCS was announced, the...

Please note this article is now deprecated due to an outdated version of JET used. The techniques however are still valid.   Introduction JET is Oracle's new mobile toolkit specifically written for developers to help them build client slide applications using JavaScript. Oracle Fusion Applications implementers are often given the requirement to create mobile, or desktop browser, based custom screens for Fusion Applications. There are many options available to the developer for...
