SMART: Making DB2 (More) Autonomic
SMART: Making DB2 (More) Autonomic Guy M. Lohman Sam S.

Keys Are, As Their Name Suggests, a Key Part of a Relational Database
The key is defined as the column or attribute of the database table. For example if a table has id, name and address as the column names then each one is known as the key for that table. We can also say that the table has 3 keys as id, name and address. The keys are also used to identify each record in the database table . Primary Key:- • Every database table should have one or more columns designated as the primary key . The value this key holds should be unique for each record in the database. For example, assume we have a table called Employees (SSN- social security No) that contains personnel information for every employee in our firm. We’ need to select an appropriate primary key that would uniquely identify each employee. Primary Key • The primary key must contain unique values, must never be null and uniquely identify each record in the table. • As an example, a student id might be a primary key in a student table, a department code in a table of all departments in an organisation. Unique Key • The UNIQUE constraint uniquely identifies each record in a database table. • Allows Null value. But only one Null value. • A table can have more than one UNIQUE Key Column[s] • A table can have multiple unique keys Differences between Primary Key and Unique Key: • Primary Key 1. A primary key cannot allow null (a primary key cannot be defined on columns that allow nulls). 2. Each table can have only one primary key. • Unique Key 1. A unique key can allow null (a unique key can be defined on columns that allow nulls.) 2. -
A Relational Multi-Schema Data Model and Query Language for Full Support of Schema Versioning?
A Relational Multi-Schema Data Model and Query Language for Full Support of Schema Versioning? Fabio Grandi CSITE-CNR and DEIS, Alma Mater Studiorum – Universita` di Bologna Viale Risorgimento 2, 40136 Bologna, Italy, email: [email protected] Abstract. Schema versioning is a powerful tool not only to ensure reuse of data and continued support of legacy applications after schema changes, but also to add a new degree of freedom to database designers, application developers and final users. In fact, different schema versions actually allow one to represent, in full relief, different points of view over the modelled application reality. The key to such an improvement is the adop- tion of a multi-pool implementation solution, rather that the single-pool solution usually endorsed by other authors. In this paper, we show some of the application potentialities of the multi-pool approach in schema versioning through a concrete example, introduce a simple but comprehensive logical storage model for the mapping of a multi-schema database onto a standard relational database and use such a model to define and exem- plify a multi-schema query language, called MSQL, which allows one to exploit the full potentialities of schema versioning under the multi-pool approach. 1 Introduction However careful and accurate the initial design may have been, a database schema is likely to undergo changes and revisions after implementation. In order to avoid the loss of data after schema changes, schema evolution has been introduced to provide (partial) automatic recov- ery of the extant data by adapting them to the new schema. -

Data Definition Language
1 Structured Query Language SQL, or Structured Query Language is the most popular declarative language used to work with Relational Databases. Originally developed at IBM, it has been subsequently standard- ized by various standards bodies (ANSI, ISO), and extended by various corporations adding their own features (T-SQL, PL/SQL, etc.). There are two primary parts to SQL: The DDL and DML (& DCL). 2 DDL - Data Definition Language DDL is a standard subset of SQL that is used to define tables (database structure), and other metadata related things. The few basic commands include: CREATE DATABASE, CREATE TABLE, DROP TABLE, and ALTER TABLE. There are many other statements, but those are the ones most commonly used. 2.1 CREATE DATABASE Many database servers allow for the presence of many databases1. In order to create a database, a relatively standard command ‘CREATE DATABASE’ is used. The general format of the command is: CREATE DATABASE <database-name> ; The name can be pretty much anything; usually it shouldn’t have spaces (or those spaces have to be properly escaped). Some databases allow hyphens, and/or underscores in the name. The name is usually limited in size (some databases limit the name to 8 characters, others to 32—in other words, it depends on what database you use). 2.2 DROP DATABASE Just like there is a ‘create database’ there is also a ‘drop database’, which simply removes the database. Note that it doesn’t ask you for confirmation, and once you remove a database, it is gone forever2. DROP DATABASE <database-name> ; 2.3 CREATE TABLE Probably the most common DDL statement is ‘CREATE TABLE’. -

How Our Worldviews Shape Our Practice
How Our Worldviews Shape Our Practice Rachel M. Goldberg This article reviews research on the effect of a conflict resolution practi- tioner’s worldview on practice. The results revealed patterns connecting worldview frames with differing uses of power. Forty-three environ- mental and intercultural practitioners were interviewed, and narrative and metaphor analysis was used to reveal key worldview orientations in their practice stories. The results are correlated in continuums and “pro- files” of the worldview orientation. The findings strengthen previous work questioning the effects of the traditional neutrality stance, deepen fieldwide arguments for the embedded nature of worldview and cul- ture, and describe new methods that reveal some of the dynamics between worldview and practice. Native American tribe spent many years struggling against a govern- Ament agency for permanent residence status on their traditional homeland (the ability to live in and use their traditional homeland). Over time, their argument became a fight about permanent homes, because this was the only way to argue for use of the land that the agency understood. For the agency representatives, permanent housing (a building) was syn- onymous with permanent residence (ability to live on and use the land). One day, the mediator who was working with the tribe asked them why they wanted permanent homes. It turned out that the area became very hot during the summer; the tribe had traditionally built temporary homes in the winter and migrated to the mountains during the hot season. It become clear that the tribe did not even really want permanent housing, but a right to reside legally in the area—in their case, a very different goal.
