Database designers

In this study, an artificial neural networkbased Bayesian regularization (ANN) model is proposed to predict the compressive strength of concrete. The database in this study includes 208 experimental results synthesized from laboratory experiments with 9 input variables related to temperature change and design material composition.

The current research project genotyped HAV RNA by using protocols and primer sets designed by HAVNET. It collected and genotyped previous HAV-positive samples in VIDRL sample bank, and the results were used to establish epidemiological and molecular database of the HAV strains. The database was used to investigate the relationship between the current diagnostic samples and the previous HAV infection cases. It was expected to identify the source of the hepatitis A infection.

In this paper, the identifying undamaged-beam status based on singular spectrum analysis (SSA) and wavelet neural networks (WNN) is presented. First, a database is built from measured sets and SSA which works as a frequency-based filter. A WNN model is then designed which consists of the wavelet frame building, wavelet structure designing and establishing a solution for training the WNN.

In chapter 3, we follow the traditional approach of concentrating on the database structures and constraints during conceptual database design. The design of application programs is typically covered in software engineering courses. this chapter also present the modeling concepts of the Entity-Relationship (ER) model, which is a popular high-level conceptual data model.

Chapter 7 discusses how to design a relational database schema based on a conceptual schema design. This chapter presented a high-level view of the database design process, and in this chapter we focus on the logical database design or data model mapping step of database design. We present the procedures to create a relational schema from an Entity-Relationship (ER) or an Enhanced ER (EER) schema.
