This volume is a collection of the most important contributions
presented at the second MFDBS conference held in Visegr d, Hungary,
June 26-30, 1989. The papers selected from more than one hundred
submissions, originating from 23 countries in 4 continents, can be
roughly divided into the following sections: theoretical
fundamentals of relational databases, logical foundations and
databases, data modelling, database design, deductive databases,
transaction management and security, concurrency control and
distributed databases. The volume reflects the current state of
knowledge and is a guide to further development in database theory.
This volume contains 24 papers presented at the Sixth International
Workshop on Database Machines. The papers cover a wide spectrum of
topics including: system architectures, storage structures,
associative memory architectures, memory resident systems,
deduction and retrospectives on maturing projects. The nature of
the papers is highly technical and presumes knowledge of database
management systems and familiarity with database machines. The book
is representative of the dual trend in the field towards (1) search
for new functionability and (2) attention to detail, completeness
and performance of prototype implementations.
The Third International Conference on Foundations of Data
Organization and Algorithms has been organized by INRIA in Paris
from June 21 to 23, 1989. Previous FODO Conferences were held in
Warsaw, 1981, and in Kyoto, 1985. The goal of this year's
conference is to present advances in techniques of permanent and
temporary data organization in different fields. New applications
such as image processing, graphics, geographic data processing,
robotics, office automation, information systems, language
translation, and expert systems have developed various data
organizations and algorithms specific to the application
requirements. The growing importance of these applications has
created a need for general studies on data organization and
algorithms as well as for specific studies on new database
management systems and on filing services. The articles submitted
for the conference were subject to the usual rigorous reviewing
process and selected on that basis. They offer an excellent
snapshot of the state of the art in the field and should prove
invaluable for computer scientists faced by the problems of data
organization which are raised by these new applications.
Did you know that there is a technology inside Excel, and Power BI,
that allows you to create magic in your data, avoid repetitive
manual work, and save you time and money? Using Excel and Power BI,
you can: Save time by eliminating the pain of copying and pasting
data into workbooks and then manually cleaning that data. Gain
productivity by properly preparing data yourself, rather than
relying on others to do it. Gain effiiciency by reducing the time
it takes to prepare data for analysis, and make informed decisions
more quickly. With the data connectivity and transformative
technology found in Excel and Power BI, users with basic Excel
skills import data and then easily reshape and cleanse that data,
using simple intuitive user interfaces. Known as "Get &
Transform" in Excel 2016, as the "Power Query" separate add-in in
Excel 2013 and 2010, and included in Power BI, you'll use this
technology to tackle common data challenges, resolving them with
simple mouse clicks and lightweight formula editing. With your new
data transformation skills acquired through this book, you will be
able to create an automated transformation of virtually any type of
data set to mine its hidden insights.
Use Microsoft 365 Excel and Excel 2021 pivot tables and pivot
charts to produce powerful, dynamic reports in minutes: take
control of your data and your business! Even if you've never
created a pivot table before, this book will help you leverage all
their flexibility and analytical power- including important recent
improvements in Microsoft 365 Excel. Drawing on more than 30 years
of cutting-edge Excel experience, MVP Bill Jelen ("MrExcel") shares
practical "recipes" for solving real business problems, expert
insights for avoiding mistakes, and advanced tips and tricks you'll
find nowhere else. By reading this book, you will: Master easy,
powerful ways to create, customize, change, and control pivot
tables Transform huge datasets into clear summary reports Instantly
highlight your most profitable customers, products, or regions Use
the data model and Power Query to quickly analyze disparate data
sources Create powerful crosstab reports with new dynamic arrays
and Power Query Build geographical pivot tables with 3D Maps
Construct and share state-of-the-art dynamic dashboards Revamp
analyses on the fly by dragging and dropping fi elds Build dynamic
self-service reporting systems Share your pivot tables with
colleagues Create data mashups using the full Power Pivot
capabilities in modern Excel versions Generate pivot tables using
either VBA on the Desktop or Typescript in Excel Online Save time
and avoid formatting problems by adapting reports with GetPivotData
Unpivot source data so it's easier to work with Use new Analyze
Data artificial intelligence to create pivot tables
This book helps you readily become familiar with Excel's power
techniques and systematically tap into more and more of that power
day by day.
There are so many power techniques built into Excel and Win 95
that you are in serious danger of missing many of them. This book
comes with an appendix listing all the functions, their syntax, and
their arguments, which helps you turn loose their considerable
power.
Bei Problemen in Technik, Natur- und Wirtschaftswissenschaften
werden haufig maximale Ergebnisse unter minimalem Aufwand gesucht.
Deshalb gewinnt die mathematische Optimierung sowohl fur Ingenieure
als auch Natur- und Wirtschaftswissenschaftler zunehmend an
Bedeutung. Das vorliegende Lehrbuch gibt eine Einfuhrung in die
lineare, nichtlineare und vektorielle Optimierung, wobei auch
Spezialfalle wie quadratische, parametrische und diskrete
Optimierung betrachtet werden. Des Weiteren wird der Gegenstand der
Spieltheorie und dynamischen Optimierung skizziert. Im Buch wird
auf Beweise verzichtet und dafur die Problematik anhand von
Beispielen illustriert. Ein zweiter Schwerpunkt des Buches liegt
auf der Berechnung der behandelten Optimierungsaufgaben mittels
Computer. Hierzu werden die Computeralgebrasysteme MAPLE,
MATHEMATICA, MATHCAD und MATLAB und das
Tabellenkalkulationsprogramm EXCEL herangezogen und
versionsunabhangig erlautert."
Time is the one thing no manager has enough of. Through goal
