Gestión de bases de datos. 2ª Edición (GRADO SUPERIOR)


Book Description

La presente obra está dirigida a los estudiantes del Ciclo Formativo Administración de Sistemas Informáticos en Red de Grado Superior, en concreto para el módulo profesional Gestión de Bases de Datos. Se cubren con cierto detalle los distintos modelos de datos predominantes en el mercado, así como los sistemas de software de bases de datos que permiten su implementación física. En primer lugar, se verán los sistemas de almacenamiento para estudiar después el modelo relacional como ejemplo de modelado que más se ha impuesto desde su creación en los años 70. Después, se estudiará cómo se tratan los datos utilizando un gestor o software de bases de datos bastante extendido y bien documentado como es MySQL y el lenguaje genérico (independiente del software) SQL, que permite llevar a cabo las distintas operaciones (consulta, inserción, modificación y borrado de datos). Posteriormente, se verá en detalle el proceso clásico de desarrollo de bases de datos, desde su concepción mediante un modelo conceptual hasta su implementación en un sistema informático. Por último, se desarrollará un ejemplo de software de bases de datos avanzado que utiliza conceptos de la orientación a objetos. Se trata de Oracle, un sistema gestor de bases objeto-relacionales que incorpora conceptos de bases de datos y de objetos tal y como se definieron según el estándar SQL1999. Todo ello con numerosos ejemplos y complementado con una serie de apéndices que amplían y completan los conceptos explicados. Así mismo, se incorporan test de conocimientos y ejercicios propuestos con la finalidad de comprobar que los objetivos de cada capítulo se han asimilado correctamente. Además, reúne los recursos necesarios para incrementar la didáctica del libro, tales como un glosario con los términos informáticos necesarios, bibliografía y documentos para ampliación de los conocimientos.

Non-Invasive Data Governance


Book Description

Data-governance programs focus on authority and accountability for the management of data as a valued organizational asset. Data Governance should not be about command-and-control, yet at times could become invasive or threatening to the work, people and culture of an organization. Non-Invasive Data Governance™ focuses on formalizing existing accountability for the management of data and improving formal communications, protection, and quality efforts through effective stewarding of data resources. Non-Invasive Data Governance will provide you with a complete set of tools to help you deliver a successful data governance program. Learn how: • Steward responsibilities can be identified and recognized, formalized, and engaged according to their existing responsibility rather than being assigned or handed to people as more work. • Governance of information can be applied to existing policies, standard operating procedures, practices, and methodologies, rather than being introduced or emphasized as new processes or methods. • Governance of information can support all data integration, risk management, business intelligence and master data management activities rather than imposing inconsistent rigor to these initiatives. • A practical and non-threatening approach can be applied to governing information and promoting stewardship of data as a cross-organization asset. • Best practices and key concepts of this non-threatening approach can be communicated effectively to leverage strengths and address opportunities to improve.

Glosario Del Banco Mundial


Book Description

This edition of the World Bank has been revised and expanded by the Terminology Unit in the Languages Services Division of the World Bank in collaboration with the English, Spanish, and French Translation Sections. The Glossary is intended to assist the Bank's translators and interpreters, other Bank staff using French and Spanish in their work, and free-lance translator's and interpreters employed by the Bank. For this reason, the Glossary contains not only financial and economic terminology and terms relating to the Bank's procedures and practices, but also terms that frequently occur in Bank documents, and others for which the Bank has a preferred equivalent. Although many of these terms, relating to such fields as agriculture, education, energy, housing, law, technology, and transportation, could be found in other sources, they have been assembled here for ease of reference. A list of acronyms occurring frequently in Bank texts (the terms to which they refer being found in the Glossary) and a list of international, regional, and national organizations will be found at the end of the Glossary.




At a Crossroads


Book Description

"Higher education in Latin America and the Caribbean has expanded dramatically in the past 15 years, as the average gross enrollment rate has more than doubled, and many new institutions and programs have been opened. Although higher education access has become more equitable, and higher education supply has become more varied, many of the 'new' students in the system are, on average, less academically ready than are their more advantaged counterparts. Furthermore, only half of higher education students, on average, complete their degree, and labor market returns to higher education vary greatly across institutions and programs. Thus, higher education is at a crossroads today. Given the region's urgency to raise productivity in a low-growth, fiscally constrained environment, going past this crossroads requires the formation of skilled human capital fast and efficiently. 'At a Crossroads: Higher Education in Latin America and the Caribbean' contributes to the discussion by studying quality, variety, and equity of higher education in Latin America and the Caribbean. The book presents comprehensive evidence on the recent higher education expansion and evolution of higher education labor market returns. Using novel data and state-of-the-art methods, it studies demand and supply drivers of the recent expansion. It investigates the behavior of institutions and students and explores the unintended consequences of large-scale higher education policies. Framing the analysis are the singular characteristics of the higher education market and the market segmentation induced by the variety of students and institutions in the system. At this crossroads, a role emerges for incentives, information, accountability, and choice."
