In this article we will discuss the Hibernate types. We will see how Hibernate provides built-in types that map to common database types. We'll also see how Hibernate allows us to implement and use custom types when these built-in types do not satisfy the application's requirements, or when we want to change the default behavior of a built-in type. As you will see, you can easily implement a custom-type class and then use it in the same way as a built-in one.
Data pros are adopting cloud computing concepts to offer databases as a service - easing management burdens and sending users to cloud nine. Learn about the three steps for getting started with database as a service.
When it comes to embedded systems and mobile devices, developers face a very important choice between flat files and an embedded database, as any future change can be very risky and expensive. However, to meet deadlines and satisfy hardware restrictions, many developers build custom solutions from scratch, preferring a quick, simple implementation to a scalable one. As the product line evolves, these solutions can become very complex and difficult to reconcile with new requirements.
draws a comparison between two approaches to ORM-centric database development. One is based on the Python SQLAlchemy ORM tools, and the other uses standard Java JPA. Which is better? The result of comparing a simple use case for both languages is quite surprising.
It has been said that the database wars are over and the relational database won. However, anyone who believes this state of affairs has led to peace and prosperity among programmers hasn't tried using a relational database to back Java™ objects lately. This article is the first of an in-depth, multipart series introducing db4o, an object-oriented alternative to today's relational databases.
This article presents an approach to constructing, producing, and employing earned value management in the accomplishment of database projects. This paper only addresses the earned value for labor. Other types of earned value address materials and facilities.
