I think offline functionality topic should become a trend in the future. Its great that Oracle already provides solution for offline – Oracle Offline Persistence toolkit. This is my second post related to offline support, read previous post – Oracle Offline Persistence Toolkit – Simple GET Response Example with JET. I have tested and explained with sample app how it works to handle simple GET response offline. While today I would like to go one step further and check how to filter offline data – shredding and querying offline.

Sample app is fetching a list of employees – Get Employees button. It shows online/offline status – see icon in top right corner. We are online and GET response was cached by persistence toolkit:

We can test offline behaviour easily – this can be done through Chrome Developer Tools – turn on Offline mode. Btw, take a look into Initiator field for GET request – it comes from Oracle Offline Persistence toolkit. As I mention it in my previous post – once persistence toolkit is enabled, all REST calls are going through toolkit, this is how it is able to cache response data: Read the complete article here.

This week I had some interesting Oracle JET discussions with a couple of developers at one of our customers. One of the things was regarding the inline use of CSS that I found in the Views of the Modules. I didn’t think that made sense so, after asking, I was told that this was because they did not find a way to use specific CSS per module. The question was if it was possible to use one specific CSS per Module in an Oracle JET Application. Besides that I thought it might also be useful to put everything that belongs to a module in its own folder. That could help developers to get a better understanding of the structure of the application. Besides that it is more like the structure of Oracle JET Composite Components where also everything that belongs to that component is under one folder.

Obviously this should be possible by explicitly loading a CSS in the view of the module. Geertjan already blogged about it : https://blogs.oracle.com/geertjan/referencing-css-from-an-oracle-jet-module. The same goes for restructuring the JET application into a more functional architecture: https://blogs.oracle.com/geertjan/restructuring-of-oracle-jet-applications

So nothing really new here, although it is a slightly different approach. Just writing up things here for my own reference. Feel free to use this if you like. In this post I will describe the implementation somewhat more detailed and have a working sample application available. For this blogpost I used the simple application that can be create on with the Oracle JET CLI. I will show you the steps to go from that to the "alternate" architecture. The goal is to have all files for one module in one specific folder. Read the complete article here.

Welcome to the 3rd article on our new Blog series about Oracle JET and Oracle Cloud.

Today we’ll start designing our application, starting with its Data Model. For that, well be focusing on Oracle’s SQL Developer Data Modeler as our tool and design the application’s underlying data model.

So, without further ado, let’s dig right in.

Data Modeling Workflow

Let’s start our SQL Developer and go right into the Data Modeler.

Open up the model browser and save the existing design with a proper, understandable name. I chose “OJetBlog-DataModel”.

Accessing the Data Modeler Browser

Save the design to give it a proper name

Once you have done this, you can start working on your Logical Model. As you know, there are several models to represent your data model, from the most high level (not bound by the RDBMS) to the Physical Model that is totally dependent on the RDBMS.

For our exercise, we’ll model our application in our Logical Model, pass it through to the Relational Model, and the Physical Model, through the generations of specific DDL for our Oracle Cloud Database. Any changes that we need to make in our database will be performed at the Logical level and then, using the SQL Developer tools, passed through our workflow and finalized in a DDL that will be executed on our DB. Keeping this workflow ensures coherence in your designs and a properly documented and maintained DB. Read the complete article here.

JET Composite Components – are useful not only to build UI widgets, but also to group and simplify JET code. In this post, I will show how to wrap JET table into composite component and use all essential features, such as properties, methods, events and slots.
Sample app code is available on GitHub. JET table is wrapped into composite component, it comes with slot for toolbar buttons:

What is the benefit to wrap such components as JET table into your own composite? To name a few:
1. Code encapsulation. Complex functionality, which requires multiple lines of HTML and JS code resides in the composite component
2. Maintenance and migration. It is easier to fix JET specific changes in single place
3. Faster development. There is less steps to repeat and less code to write for developer, when using shorter definition of the wrapper composite component
Sample application implements table-redsam component, for the table UI you can see above. Here is component usage example, very short and clean: Read the complete article. here

Loyco is using Oracle JET to build and run their financial reporting application. This application improves user experience and allows easy navigation through financial data reports. Without extra roundtrips to the REST back-end service, drilldowns related to Cash, Subledger, Payments and Journal modules are displayed using such JET components as tables, lists and charts. All this allows seamless and fast data browsing on the client side. The application is relying on a dynamic UI, which provides filter and sort options for data based on such criteria as financial year, month, etc. There are no static filters defined, the UI is driven by dynamic master-detail data coming from the back-end. The Oracle JET based Loyco Finance application was built by the Red Samurai Consulting team. Read the complete article here.
