  • 2.4. Constraints
    PostgreSQL 7.3 Documentation Prev Chapter 2. Data Definition Next 2.4. Constraints Data types are a way to limit the kind of data that can be stored in a table. For many applications, however, the constraint they provide is too coarse. For example, a column containing a product price should probably only accept positive values. But there is no data type that accepts only positive numbers. Another issue is that you might want to constrain column data with respect to other columns or rows. For example, in a table containing product information, there should only be one row for each product number. To that end, SQL allows you to define constraints on columns and tables. Constraints give you as much control over the data in your tables as you wish. If a user attempts to store data in a column that would violate a constraint, an error is raised. This applies even if the value came from the default value definition. 2.4.1. Check Constraints A check constraint is the most generic constraint type. It allows you to specify that the value in a certain column must satisfy an arbitrary expression. For instance, to require positive product prices, you could use: CREATE TABLE products ( product_no integer, name text, price numeric CHECK (price > 0) ); As you see, the constraint definition comes after the data type, just like default value definitions. Default values and constraints can be listed in any order. A check constraint consists of the key word CHECK followed by an expression in parentheses. The check constraint expression should involve the column thus constrained, otherwise the constraint would not make too much sense.

  • Reasoning Over Large Semantic Datasets
    R O M A TRE UNIVERSITA` DEGLI STUDI DI ROMA TRE Dipartimento di Informatica e Automazione DIA Via della Vasca Navale, 79 – 00146 Roma, Italy Reasoning over Large Semantic Datasets 1 2 2 1 ROBERTO DE VIRGILIO ,GIORGIO ORSI ,LETIZIA TANCA , RICCARDO TORLONE RT-DIA-149 May 2009 1Dipartimento di Informatica e Automazione Universit`adi Roma Tre {devirgilio,torlone}@dia.uniroma3.it 2Dipartimento di Elettronica e Informazione Politecnico di Milano {orsi,tanca}@elet.polimi.it ABSTRACT This paper presents NYAYA, a flexible system for the management of Semantic-Web data which couples an efficient storage mechanism with advanced and up-to-date ontology reasoning capa- bilities. NYAYA is capable of processing large Semantic-Web datasets, expressed in a variety of formalisms, by transforming them into a collection of Semantic Data Kiosks that expose the native meta-data in a uniform fashion using Datalog±, a very general rule-based language. The kiosks form a Semantic Data Market where the data in each kiosk can be uniformly accessed using conjunctive queries and where users can specify user-defined constraints over the data. NYAYA is easily extensible and robust to updates of both data and meta-data in the kiosk. In particular, a new kiosk of the semantic data market can be easily built from a fresh Semantic- Web source expressed in whatsoever format by extracting its constraints and importing its data. In this way, the new content is promptly available to the users of the system. The approach has been experimented using well known benchmarks with very promising results. 2 1 Introduction Ever since Tim Berners Lee presented, in 2006, the design principles for Linked Open Data1, the public availability of Semantic-Web data has grown rapidly.

  • CSC 443 – Database Management Systems Data and Its Structure
    CSC 443 – Database Management Systems Lecture 3 –The Relational Data Model Data and Its Structure • Data is actually stored as bits, but it is difficult to work with data at this level. • It is convenient to view data at different levels of abstraction . • Schema : Description of data at some abstraction level. Each level has its own schema. • We will be concerned with three schemas: physical , conceptual , and external . 1 Physical Data Level • Physical schema describes details of how data is stored: tracks, cylinders, indices etc. • Early applications worked at this level – explicitly dealt with details. • Problem: Routines were hard-coded to deal with physical representation. – Changes to data structure difficult to make. – Application code becomes complex since it must deal with details. – Rapid implementation of new features impossible. Conceptual Data Level • Hides details. – In the relational model, the conceptual schema presents data as a set of tables. • DBMS maps from conceptual to physical schema automatically. • Physical schema can be changed without changing application: – DBMS would change mapping from conceptual to physical transparently – This property is referred to as physical data independence 2 Conceptual Data Level (con’t) External Data Level • In the relational model, the external schema also presents data as a set of relations. • An external schema specifies a view of the data in terms of the conceptual level. It is tailored to the needs of a particular category of users. – Portions of stored data should not be seen by some users. • Students should not see their files in full. • Faculty should not see billing data. – Information that can be derived from stored data might be viewed as if it were stored.

  • Data Base Lab the Microsoft SQL Server Management Studio Part-3
    Data Base Lab Islamic University – Gaza Engineering Faculty Computer Department Lab -5- The Microsoft SQL Server Management Studio Part-3- By :Eng.Alaa I.Haniy. SQL Constraints Constraints are used to limit the type of data that can go into a table. Constraints can be specified when a table is created (with the CREATE TABLE statement) or after the table is created (with the ALTER TABLE statement). We will focus on the following constraints: NOT NULL UNIQUE PRIMARY KEY FOREIGN KEY CHECK DEFAULT Now we will describe each constraint in details. SQL NOT NULL Constraint By default, a table column can hold NULL values. The NOT NULL constraint enforces a column to NOT accept NULL values. The NOT NULL constraint enforces a field to always contain a value. This means that you cannot insert a new record, or update a record without adding a value to this field. The following SQL enforces the "PI_Id" column and the "LName" column to not accept NULL values CREATE TABLE Person ( PI_Id int NOT NULL, LName varchar(50) NOT NULL, FName varchar(50), Address varchar(50), City varchar(50) ) 2 SQL UNIQUE Constraint The UNIQUE constraint uniquely identifies each record in a database table. The UNIQUE and PRIMARY KEY constraints both provide a guarantee for uniqueness or a column or set of columns. A PRIMARY KEY constraint automatically has a UNIQUE constraint defined on it. Note that you can have many UNIQUE constraints per table, but only one PRIMARY KEY constraint per table. SQL UNIQUE Constraint on CREATE TABLE The following SQL creates a UNIQUE

  • 8 the Effectiveness of Test Coverage Criteria for Relational Database Schema Integrity Constraints
    The Effectiveness of Test Coverage Criteria for Relational Database Schema Integrity Constraints PHIL MCMINN and CHRIS J. WRIGHT, University of Sheffield GREGORY M. KAPFHAMMER, Allegheny College Despite industry advice to the contrary, there has been little work that has sought to test that a relational database’s schema has correctly specified integrity constraints. These critically important constraints ensure the coherence of data in a database, defending it from manipulations that could violate requirements such as “usernames must be unique” or “the host name cannot be missing or unknown.” This article is the first to propose coverage criteria, derived from logic coverage criteria, that establish different levels of testing for the formulation of integrity constraints in a database schema. These range from simple criteria that mandate the testing of successful and unsuccessful INSERT statements into tables to more advanced criteria that test the formulation of complex integrity constraints such as multi-column PRIMARY KEYs and arbitrary CHECK constraints. Due to different vendor interpretations of the structured query language (SQL) specification with regard to how integrity constraints should actually function in practice, our criteria crucially account for the underlying semantics of the database management system (DBMS). After formally defining these coverage criteria and relating them in a subsumption hierarchy, we present two approaches for automatically generating tests that satisfy the criteria. We then describe the results of an empirical study that uses mutation analysis to investigate the fault-finding capability of data generated when our coverage criteria are applied to a wide variety of relational schemas hosted by three well-known and representative DBMSs— HyperSQL, PostgreSQL, and SQLite.
