Unique to the popular Grails web framework is its architecture. While other frameworks are built from the ground up, Grails leverages existing and proven technologies that already have advanced functionality built in. One of the key technologies in this architecture is Hibernate, on top of which Grails builds its GORM (Grails Object Relational Mapping) model layer. This provides Grails a persistence solution.
Microsoft’s ADO.NET Entity Framework, known widely as EF, introduced out-of-thebox
Object Relational Mapping to .NET and Visual Studio. Central to Entity Framework
was the Entity Data Model, a conceptual model of your application domain that
maps back to the schema of your database. This conceptual model describes the core
classes in your application. Entity Framework uses this conceptual model while querying
from the database, creating objects from that data and then persisting changes back
to the database....

Relational databases are indisputably at the core of the modern enterprise.
While modern programming languages, including JavaTM, provide an intuitive,
object-oriented view of application-level business entities, the enterprise data
underlying these entities is heavily relational in nature. Further, the main strength
of the relational model—over earlier navigational models as well as over later
OODB models—is that by design it is intrinsically agnostic to the programmatic
manipulation and application-level view of the data that it serves up...
JDBC has simplified database access in Java applications, but a few nagging wrinkles remain—namely, persisting Java objects to relational databases. With this book, you’ll learn how the Spring Framework makes that job incredibly easy with dependency injection, template classes, and object-relational-mapping (ORM).
Through sample code, you’ll discover how Spring streamlines the use of JDBC and ORM tools such as Hibernate, the Java Persistence API (JPA), and Java Data Objects (JDO).
Despite mounting public concern, the factors influencing this illness are not fully understood,
especially for children. Medical research has demonstrated that asthma is both a chronic and acute illness.
In the chronic aspect, an individual’s airways are persistently inflamed and their immune system is hyper-
responsive, but the causes of this remain largely unknown (American Lung Association (2000)).
