Introducing Reladomo - Enterprise Open Source Java ORM, Batteries Included! (Part 2)
Goldman Sachs is widely known as a leader in investment banking, but they are very much a leading technology firm as well. Continuing our exploration of Reladomo, the primary Java ORM used at GS and now open source, GS Technology Fellow, Mohammad Rezaei looks at advanced features, such as sharding, caching, bitemporal access, performance, and testing.

Interview with Entity Modelling Tool Creator, Frans Bouma
Our first .NET interview of the year is with Frans Bouma of the entity modeling tool LLBLGen Pro. This tool has been around for almost as long as .NET itself, but being a commercial product it isn’t as well-known as the free alternatives.

Advanced Use Cases for the Repository Pattern in .NET
In our previous article, we looked at the basic patterns needed to implement a repository. In many cases these patterns were such a thin layer around the underlying data access technology they were essentially unnecessary. However, once you have a repository in place, many new opportunities become available.

Implementation Strategies for the Repository Pattern with Entity Framework, Dapper, and Chain
This article will focus on the basic functionality that one would find in a typical repository created with .NET. We’ll look at both general functionality and how that functionality would be implemented using three different styles of ORM: Entity Framework, Dapper, and Tortuga Chain.

Starcounter vs. ORM and DDD
The so-called “object-relation impedance mismatch” has long been discussed in engineering circles. Most attempts at a solution rely try to mask the issue by pulling logic into the application tier. Kostiantyn Cherniavskyi looks at these issues and shows how many of them can be solved with hybrid databases such as Starcounter.

Metadata-Driven Design: Designing a Flexible Engine for API Data Retrieval
Bulk data is commonly accessed via files & FTP. As the world moves toward APIs to facilitate collaboration, what are the requirements for data APIs? This article describes a meta-data driven architecture for bulk data ingestion. Two APIs operate in parallel to provide data changes as well as the data records themselves. An example demonstrates how API responses are parameterized using meta-data.

Data Modeling in Graph Databases: Interview with Jim Webber and Ian Robinson
Data modeling with Graph databases requires a different paradigm than modeling in Relational or other NoSQL databases like Document databases, Key Value data stores, or Column Family databases. InfoQ spoke with Jim Webber and Ian Robinson about data modeling efforts when using Graph databases.

ActiveJPA – Active Record Pattern for JPA
ActiveJPA is a Java implementation of Martin Fowler’s Active Record pattern that wraps around JPA and provides useful abstractions to simplify data access. With ActiveJPA, models themselves act as a DAO and interact with the database without requiring additional code for the DAL. In this article the primary committer discusses ActiveJPA and provides plenty of usage examples.

Don’t jump the SQL ship just yet
The SQL language has been evolving steadily over the last two decades. At the same time, the verbosity caused by the JDBC API in Java client code and the lack of first class SQL support within the Java language have led to the introduction of ORMs such as Hibernate, which was later standardised into JPA and the Criteria API.If SQL and JPA are diverging, where will our data interaction patterns go?
