  • 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).

  • 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....

  • The need for Business Intelligence (BI) solutions and data analysis has always existed, and so have different approaches to fulfill this need. Traditional BI software has heavily relied on techniques that have been around and persisted through the decades, but newer technologies have emerged in recent times that have proven to be more flexible and, therefore, more adequate for the evolving environment in which they are used. QlikView is an example of this kind of disruptive technology, a kind of software that changes the rules of the game. QlikView is different; that's a fact.

  • The current study was undertaken in a new manufactured house set up as a research facility. The plan was to conduct longitudinal measurements of VOC concentrations in the house along with measurements of key physical parameters including house air change rate, indoor and outdoor temperature and relative humidity, and wind conditions over a period of approximately one year. The primary objective was to evaluate changes in the emissions of formaldehyde and other VOCs in response to time, house air change rate, and the other parameters.

  • Our study shows that, in spite of a gradual decrease, the incidence rates of pulmonary tuberculosis in immigrants remain high even a decade after immigration. The persistent high incidence rates are consistent with results of previous studies (2–5). Our study combines data on all immigrant patients in whom tuberculosis was detected and all legal immigrants present in a 5-year period in a low incidence country, enabling detailed analysis with a long follow-up period. We did not find a steep decline in incidence rates after immigration.

  • Preliminary analysis of the data reveals some noteworthy similarities and differences between Chile and the other countries considered. Over this sample period, Chilean interest rates are on average higher, more volatile, and less persistent than the interest rates for the other countries. However, in Chile, the degree of co-movement between retail bank interest rates and the money market rate is essentially the same as in other countries.

  • Bernanke and Gertler (1989) focus on the investment decision of rms. There is asymmetric information between lenders and entrepreneurs: while entrepreneurs know the protability of their investment projects, lenders must pay an auditing cost to observe the project's return. This information asymmetry is the key source of persistence in the model. A positive productivity shock increases savings of entrepreneurs and lowers agency costs, making it easier for them to obtain external nance.
