GOR e.V. Homepage – Willkommen…
Die GOR ist eine gemeinnützige Gesellschaft. Sie entstand zum 01.01.1998 durch Verschmelzung der “Deutschen Gesellschaft für Operations Research” (DGOR) und der “Gesellschaft für Mathematik, Ökonomie und Operations Research” (GMÖOR). Ihre zentrale Aufgabe besteht darin, die Verbreitung und den Einsatz von Operations Research in Wissenschaft und Praxis zu fördern. Dies geschieht in erster Linie mit Hilfe von Fachpublikationen, Tagungen, Arbeitsgruppen sowie im Wege der Förderung des wissenschaftlichen Nachwuchses.

Oracle Modernization Solutions (Taschenbuch) – von Tom Laszewski (Autor), Jason Williamson (Autor)

Oracle Modernization Solutions (Taschenbuch) – von Tom Laszewski (Autor), Jason Williamson (Autor)
Oracle Modernization Solutions shows you how to modernize a legacy mainframe application using the modernization approaches of SOA Integration and Re-architecture. The book is unique in that it identifies a specific set of implementation tools and targets the Oracle Database and Fusion Middleware as the end architecture. Legacy system architects, project managers, program managers, developers, database architects and decision makers who own mainframe and heterogeneous systems, and are tasked with modernization will all find this book useful. The book assumes some knowledge of mainframes, J2EE, SOA, and Oracle technologies. The reader should have some background in programming and database design.

Algorithms for the construction and especially for the modification of parsers for programming languages are described. The table for an LR(1) parser is generated from a grammar by the intermediate steps LR(0), NQLALR(1), LALR(1) and general LR(1). The more powerful (and more expensive) methods are used only when necessary.

The “incremental” construction starts with (1) a grammar and the corresponding table and (2) with a set of productions which are (2.1) to be added to or (2.2) to be deleted from the grammar. The existing table then is modified such that it corresponds again to the new grammar. Even if at the extreme the productions are added one by one, measurements with grammars for usual programming languages show only a factor in computing time between 4 and 13, compared with the normal “en-bloc”-approach. For frequent changesof the grammar of a programming language, the incremental method therefore should significantly reduce the effort for the parser construction.

“Real Programmers Don’t Use PASCAL” ———————————–

Back in the good old days — the “Golden Era” of computers, it

was easy to separate the men from the boys (sometimes called “Real Men”

and “Quiche Eaters” in the literature). During this period, the Real

Men were the ones that understood computer programming, and the Quiche

Eaters were the ones that didn’t. A real computer programmer said

things like “DO 10 I=1,10” and “ABEND” (they actually talked in capital

letters, you understand), and the rest of the world said things like

“computers are too complicated for me” and “I can’t relate to computers

— they’re so impersonal”. (A previous work [1] points out that Real

Men don’t “relate” to anything, and aren’t afraid of being impersonal.)

DB2 packages: Concepts, examples, and common problems by John Chun + Paolo Cirone
What are packages?Packages in DB2 are control-structure database objects that contain executable forms of SQL statements or placement holders for executable forms. In DB2 for Linux©, UNIX©, and Windows©, packages may also be referred to as access plans. Packages are stored in the database system catalog tables.

If an application intends to access a database using static SQL, the application developer must embed the appropriate SQL statements in the program source code. When the program source code is converted to an executable object (static SQL) or executed (dynamic SQL), the strategy for executing each embedded SQL statement is stored in a package as a single section. Each section is a bound form of the embedded SQL statement, and this form contains information such as which index to use and how to use the index (basically an access plan).

DB2 packages are used to execute SQL statements on the database server.
