Every action in SQL Server - queries, updates, whatever - leaves a set of tiny footprints; SQL Server records all that valuable data and makes it visible through Dynamic Management Views, or DMVs. A DBA or developer can use this incredibly detailed information to significantly improve the performance of queries and better understand what's really going on inside a SQL Server system

Built-In Database Objects In addition to creating the database files, several other structures are created. Data dictionary: Contains descriptions of the objects in the database Dynamic performance tables: Contains information used by the database administrator (DBA) to monitor and tune the database and instance PL/SQL packages: Program units adding functionality to the database. These packages are created when the catproc.sql script is run after the CREATE DATABASE command. PL/SQL packages will not be discussed within the scope of this course.

We assume that every instrument of interest can be assigned a fair value. If the payoff stream of the instrument is ,wedenoteitsfairvalue  Following GAAP accounting rules, we view the fair value as the price at which the instrument could be sold “in an orderly transaction”. For instruments traded in a market, fair values can be read off market prices. For nontraded instruments, such as loans, fair values have to be constructed from the payoffs of comparable instruments. The fair values of fixed income instruments exhibit a low-dimensional factor structure.

It focuses on the complexity of HIV risk dynamics, as well as the challenges of implementing effective HIV/AIDS intervention programmes, and highlights achievements despite resource constraints. Through qualitative research techniques, the study reflects not only the views and opinions of management, but also the experiences of ordinary employees as participants in HIV/AIDS interventions.

In this chapter, you will learn how to design, create, and use XML web services, and most importantly from the exam point of view, you will learn how to control the environment of particular XML web services. You will work with both static and dynamic discovery of XML web services, and use the UDDI protocol to publish and locate an XML web service. The exam draws heavily from material in this chapter, so be certain that you are familiar with the terms and concepts I discuss.

Large herbivores are, and have for a long time been, among the major drivers for forming the shape and function of terrestrial ecosystems. These animals may modify primary production, nutrient cycles, soil properties, fire regimes as well as other biota. Some large herbivore species/populations are at the edge of extinction and great effort is being made to save them. Other species/populations are under discussion for reintroduction. Still other species occur in dense populations and cause conflicts with other land use interests.

We develop and implement a framework in which prior views and empirical evidence about pricing models and managerial skill can be incorporated formally into the invest- ment decision. Our framework relies on a set of passive indexes or \assets," consisting of nonbenchmark assets as well as the benchmark assets prescribed by a pricing model. A common interpretation of alpha, the intercept in a regression of the fund's excess return on the benchmarks, is that it represents the skill of the fund's manager in selecting mispriced securities.

Once you decide on how your disks should be configured, you implement the disk configurations through the Disk Management utility. This utility allows you to view and manage your physical disks and volumes. In this chapter, you will learn how to manage both types of storage and upgrade from basic storage to dynamic storage.

We think this book is unique in that it uses a novel and logical approach to present discussions of this topic from three general perspectives: scientific, social, and economic, and the integration within these important areas. We think this book is somewhat different than other environmental management books since we offer a more balanced view of the topic – many of the books available today concentrate primarily on just one of these three perspectives.

Our framework assumes that funds' sensitivities to passive assets are constant over time. One way of relaxing this assumption is to model these coe±cients as linear functions of state variables, as for example in Ferson and Schadt (1996) and Shanken (1990). In such a modi¯cation, passive asset returns scaled by the state variables can be viewed as returns on additional passive assets (dynamic passive strategies), and the approach developed here could be extended to such a setting. Another approach to dealing with temporal variation in parameters could employ data on fund holdings.

The modules ‘Psychology of Change Projects’ and portions of the modules ‘Project Management’, ‘Communication Management…’ and ‘Silicon Valley…’ constitute the communications and leadership view on change. Coordinated by experienced executives, students get in touch with tools and concepts for business case planning, project management, and financial aspects of change projects. Less theoretical, but valuable personal experience can be gained in a one-week outdoor module that takes place in the mountains.
