Object/Relational Mapping (ORM) is a technique that maps object-oriented classes and properties to relational database tables and fields. ORM leverages existing object-oriented programming skills and provides an abstraction layer over databases. There are important differences between ORM and traditional data access approaches like ADO.NET in areas like data binding, business logic implementation, and support for multi-tier architectures.

한국 표준(?) 자바셋(Java 1.6+Spring 3.x+MyBatis)과 Monolithic 아키텍처를 사용하고 있었던 제 조직 내에서 기술적 변화를 이끌어가는 것에 관련된 내용입니다.
변화를 유도하기 위해서 어떻게 해야 하는지가 핵심이며,
Architecture, Frontend, Backend, 방법론/프로세스의 영역을 각각의 단계로 나누어서 Phase1을 수행한 것과 Phase2를 수행 중인 내용에 대해서도 다룹니다.
Phase1
- Architecture : Frontend / Backend 명시적 분리
- Frontend : Angular.js, Grunt, Bower 도입
- Backend : Java 1.7/Spring4, ORM 도입
- 방법론/프로세스 : Scrum, Git
Phase2
- Architecture : Micro-Service Architecture(MSA)
- Frontend : Content Router, E2E Test
- Backend : Polyglot, Multi-Framework
- 방법론/프로세스 : Scrum+JIRA, Git Branch Policy, Pair Programming, Code Workshop
When things can't be done in such a way that a small change to the db causes many changes and recompilation of your app is this really agile? Do you really believe it or had sworn to it? I use my own technique to minimize or completety eliminate this common problem. Come to see what you might never heard of.
2006 DDD4: Data access layers - Convenience vs. Control and Performance?Daniel Fisher
How do you manage data in memory? Row as result-set? Rational like in a database? As domain objects?
If you need to map data to objects the easiest solution seems to be an O/R-Mapper. The thin red line lays
between losing control over data handling and performance and applying developer convenience and flexibility.
This session introduces a solution from a customer project that reduces code duplicates in data access code,
still provides flexibility and control as well as performant data access. See how you can develop a
transparent and reusable data access layer which comes with O/R-Mapping functionality by just making
intensive use of object oriented principles.
DCOM (Distributed Component Object Model) and CORBA (Common Object Request Broker Architecture) are two popular distributed object models. In this paper, we make architectural comparison of DCOM and CORBA at three different layers: basic programming architecture, remoting architecture, and the wire protocol architecture.
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.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
