Two Takeaways Regarding Agile Culture

By | 20.09.2017|Events|

A few days ago I had an interesting discussion with my wife which made me think about processes and culture again. To understand my reasoning one has to know that my wife is a classic business person. She has several business degrees and is a consultant working as project and process manager focusing on process optimisation and automation for several large clients. Within this area most people in her role will likely interact with IT departments and inevitably get into contact with some agile development process. As agile processes and principles are somehow disconnected from what most business students and professionals learn regarding project management, my wife got serious about the topic and took part in an agile training. Our discussion started after this training. Within this blog post I want to share my two takeaways regarding agile culture I gained from this discussion.

Wide Column Database Schema Design

By | 19.09.2017|Software Engineering|

Because relational database management systems have dominated IT for over 30 years, it is hardly surprising that although a vast amount of literature and material with regards to database schema design is available, most of it focuses on those traditional database systems. However, since NoSQL systems raised in popularity since 2007, knowledge of relational schema design is not sufficient any more. During this post I am going to outline differences and considerable aspects when doing the same for wide column database systems (and especially Apache Cassandra). Before going into any details, I will provide a brief recap on data modelling in general as well as techniques targeting traditional RDBMS. After reading this post, you will be able to understand why data modelling for NoSQL systems like Apache Cassandra follows different rules and what is necessary to design schemas for those systems.

Creating Generic Credentials in Oracle FMW 12c

By | 12.09.2017|Oracle FMW|

Some external components require some form of authentication before allowing their services to be accessed. Developing components or applications often comes with the question of where to store the respective credentials needed to connect those external services. Oracle FMW provides a Credential Store in which these credentials can be managed in a central and secure place. It also provides a set of functions that can be used with WLST to create, list and edit those credentials. Unfortunately these functions only allow you to create password credentials and not generic credentials. In this blog I will demonstrate how to create these generic credentials using WLST.

Access OSB Resources using Java

By | 22.08.2017|Oracle SOA|

Every now and then you might want to store some configurations in simple configuration files and use them as OSB Resources in pipelines. In most cases OSB functionality is sufficient to fulfil your requirements. However sometimes you might not be able to get to your goal directly. Recently, I had to retrieve a list of all values in a specific domain column within a Domain Value Map (DVM). As DVMs are primarily used to map one domain value to one or multiple other domains, existing DVM functions do not provide the capability to retrieve all values from a domain column. Therefore, I developed a Java Callout to get the desired result. The solution is applicable to all OSB resource types. This blog post presents the basic concepts used to implement a solution.
