A Definition of Database Design Standards for Human Rights Agencies
A Definition of Database Design Standards for Human Rights Agencies by Patrick Ball, et al. AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE 1994 TABLE OF CONTENTS Introduction Definition of an Entity Entity versus Role versus Link What is a Link? Presentation of a Data Model Rule-types with Rule Examples and Instance Examples . 6.1 Type of Rule: Act . 6.2 Type of Rule: Relationship . 6.3 Rule-type Name: Biography Rule Parsimony: the Trade between Precision and Simplicity xBase Table Design Implementation Example . 8.1 xBase Implementation Example . 8.2 Abstract Fields & Data Types SQL Database Design Implementation Example . 9.1 Querying & Performance . 9.2 Main Difference . 9.3 Storage of the Rules in SQL Model 1. Introduction In 1993, HURIDOCS published their Standard Human Rights Event Formats (Dueck et al. 1993a) which describe standards for the collection and exchange of information on human rights abuses. These formats represent a major step forward in enabling human rights organizations to develop manual and computerized systems for collecting and exchanging data. The formats define common fields for collection of human rights event, victim, source, perpetrator and agency intervention data, and a common vocabulary for many of the fields in the formats, for example occupation, type of event and geographical location. The formats are designed as a tool leading toward both manual and computerized systems of human rights violation documentation. Before organizations implement documentation systems which will meet their needs, a wide range of issues must be considered. One of these problems is the structural problems of some data having complex relations to other data. -
Xbase++ Language Concepts for Newbies Geek Gatherings Roger Donnay
Xbase++ Language Concepts for Newbies Geek Gatherings Roger Donnay Introduction Xbase++ has extended the capabilities of the language beyond what is available in FoxPro and Clipper. For FoxPro developers and Clipper developers who are new to Xbase++, there are new variable types and language concepts that can enhance the programmer's ability to create more powerful and more supportable applications. The flexibility of the Xbase++ language is what makes it possible to create libraries of functions that can be used dynamically across multiple applications. The preprocessor, code blocks, ragged arrays and objects combine to give the programmer the ability to create their own language of commands and functions and all the advantages of a 4th generation language. This session will also show how these language concepts can be employed to create 3rd party add-on products to Xbase++ that will integrate seamlessly into Xbase++ applications. The Xbase++ language in incredibly robust and it could take years to understand most of its capabilities, however when migrating Clipper and FoxPro applications, it is not necessary to know all of this. I have aided many Clipper and FoxPro developers with the migration process over the years and I have found that only a basic introduction to the following concepts are necessary to get off to a great start: * The Xbase++ Project. Creation of EXEs and DLLs. * The compiler, linker and project builder . * Console mode for quick migration of Clipper and Fox 2.6 apps. * INIT and EXIT procedures, DBESYS, APPSYS and MAIN. * The DBE (Database engine) * LOCALS, STATICS, PRIVATE and PUBLIC variables. * STATIC functions. -

Referential Integrity in Sqlite
CS 564: Database Management Systems University of Wisconsin - Madison, Fall 2017 Referential Integrity in SQLite Declaring Referential Integrity (Foreign Key) Constraints Foreign key constraints are used to check referential integrity between tables in a database. Consider, for example, the following two tables: create table Residence ( nameVARCHARPRIMARY KEY, capacityINT ); create table Student ( idINTPRIMARY KEY, firstNameVARCHAR, lastNameVARCHAR, residenceVARCHAR ); We can enforce the constraint that a Student’s residence actually exists by making Student.residence a foreign key that refers to Residence.name. SQLite lets you specify this relationship in several different ways: create table Residence ( nameVARCHARPRIMARY KEY, capacityINT ); create table Student ( idINTPRIMARY KEY, firstNameVARCHAR, lastNameVARCHAR, residenceVARCHAR, FOREIGNKEY(residence) REFERENCES Residence(name) ); or create table Residence ( nameVARCHARPRIMARY KEY, capacityINT ); create table Student ( idINTPRIMARY KEY, firstNameVARCHAR, lastNameVARCHAR, residenceVARCHAR REFERENCES Residence(name) ); or create table Residence ( nameVARCHARPRIMARY KEY, 1 capacityINT ); create table Student ( idINTPRIMARY KEY, firstNameVARCHAR, lastNameVARCHAR, residenceVARCHAR REFERENCES Residence-- Implicitly references the primary key of the Residence table. ); All three forms are valid syntax for specifying the same constraint. Constraint Enforcement There are a number of important things about how referential integrity and foreign keys are handled in SQLite: • The attribute(s) referenced by a foreign key constraint (i.e. Residence.name in the example above) must be declared UNIQUE or as the PRIMARY KEY within their table, but this requirement is checked at run-time, not when constraints are declared. For example, if Residence.name had not been declared as the PRIMARY KEY of its table (or as UNIQUE), the FOREIGN KEY declarations above would still be permitted, but inserting into the Student table would always yield an error. -

Introduction to MS-DOS
1.Introduction to MS-DOS : MS-DOS (Microsoft Disk Operating System) was the Microsoft-marketed version of the first widely-installed operating system in personal computers. It was essentially the same operating system that (Bill Gates's) young company developed for IBM as Personal Computer - Disk Operating System in 1981. Most users of either DOS system simply referred to their system as Disk Operating System. Like PC-DOS, MS-DOS was (and still is) a non-graphical line-oriented command- driven operating system, with a relatively simple interface but not overly "friendly" user interface. Its prompt to enter a command looks like this: C:\> MS-DOS does not care about anything called an icon, wallpaper or screen saver. Rather than being considered as a Graphical User Interface (GUI) MS-DOS is what is known as a command-line interface. You type commands on what is called the command line. MS-DOS is a single-user, single-tasking computer operating system. In spite of its very small size and relative simplicity, it is one of the most successful operating systems that has been developed to date. In DOS, a file name consists of eight character followed by a 3 character file extension. The size of a file is restricted to a 4 byte file descriptor, which limits a file’s maximum size to approximately 4 billion characters. The first release of DOS could not read or write to disk drives so users could only read and write to a floppy disc. DOS was not a state of the art operating system, even for its time. -

For SQL-engine DBMSs, these relationship-specifications and actions relate to value congruence between the value-set of a primary key’s column(s) and the value-set of a Foreign key’s column(s). When either a Update or Delete action occurs that violates the value congruence, a Referential Action occurs. The actions depend on whether the Referential Action is specified. In ANSI SQL Standards, the four referential integrity actions: No Action, Cascade, or Set Null or Set Default. In Clarion, the five referential integrity actions are: None, Restrict, Cascade, Clear, Cascade Server, ClearServer and Restrict Server.
