Finding Oracle® Table Metadata: When PROC CONTENTS Is Not Enough Jeremy W
Finding Oracle® Table Metadata: When PROC CONTENTS Is Not Enough Jeremy W. Poling, B&W Y-12 L.L.C., Oak Ridge, TN ABSTRACT Complex Oracle® databases often contain hundreds of linked tables. For SAS/ACCESS® Interface to Oracle software users who are unfamiliar with a database, finding the data they need and extracting it efficiently can be a daunting task. For this reason, a tool that extracts and summarizes database metadata can be invaluable. This paper describes how Oracle table metadata can be extracted from the Oracle data dictionary using the SAS/ACCESS LIBNAME statement in conjunction with traditional SAS® DATA step programming techniques. For a given Oracle table, we discuss how to identify the number of observations and variables in the table, variable names and attributes, constraints, indexes, and linked tables. A macro is presented which can be used to extract all the aforementioned metadata for an Oracle table and produce an HTML report. Once stored as an autocall macro, the macro can be used to quickly identify helpful information about an Oracle table that cannot be seen from the output of PROC CONTENTS. This paper assumes that the reader has a basic understanding of DATA step programming, the macro language, and the SAS/ACCESS LIBNAME statement. A basic understanding of relational database management system concepts is also helpful, but not required. INTRODUCTION Metadata is typically defined simply as “data about data.” For any SAS data set, a programmer can view useful metadata simply by using PROC CONTENTS. But, what if the table of interest resides in an Oracle database? Unfortunately, finding Oracle table metadata is not quite as straightforward as finding SAS data set metadata. -
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. -
Blockchain Database for a Cyber Security Learning System
Session ETD 475 Blockchain Database for a Cyber Security Learning System Sophia Armstrong Department of Computer Science, College of Engineering and Technology East Carolina University Te-Shun Chou Department of Technology Systems, College of Engineering and Technology East Carolina University John Jones College of Engineering and Technology East Carolina University Abstract Our cyber security learning system involves an interactive environment for students to practice executing different attack and defense techniques relating to cyber security concepts. We intend to use a blockchain database to secure data from this learning system. The data being secured are students’ scores accumulated by successful attacks or defends from the other students’ implementations. As more professionals are departing from traditional relational databases, the enthusiasm around distributed ledger databases is growing, specifically blockchain. With many available platforms applying blockchain structures, it is important to understand how this emerging technology is being used, with the goal of utilizing this technology for our learning system. In order to successfully secure the data and ensure it is tamper resistant, an investigation of blockchain technology use cases must be conducted. In addition, this paper defined the primary characteristics of the emerging distributed ledgers or blockchain technology, to ensure we effectively harness this technology to secure our data. Moreover, we explored using a blockchain database for our data. 1. Introduction New buzz words are constantly surfacing in the ever evolving field of computer science, so it is critical to distinguish the difference between temporary fads and new evolutionary technology. Blockchain is one of the newest and most developmental technologies currently drawing interest. -

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’. -

The naïve observer may conclude that such variety of database replication from both academia and industry. However, replication systems indicates a solved problem; the reality, academic groups often attack replication problems in isolation, however, is the exact opposite. Replication still falls short of overlooking the need for completeness in their solutions, while customer expectations, which explains the continued interest in developing new approaches, resulting in a dazzling variety of commercial teams take a holistic approach that often misses offerings. opportunities for fundamental innovation. This has created over time a gap between academic research and industrial practice. Even the “simple” cases are challenging at large scale. We deployed a replication system for a large travel ticket brokering This paper aims to characterize the gap along three axes: system at a Fortune-500 company faced with a workload where performance, availability, and administration.

What Is a Database? Differences Between the Internet and Library
What is a Database? Library databases are mostly full-text material (in their entirety) and summaries or descriptions of articles. They are collections of articles from newspapers, magazines and journals and electronic reference sources. Databases are selected for the quality and variety of resources they offer and are accessed using the Internet. Your library pays for you to have access to a number of relevant databases. You support this with your tuition, so get the most out of your money! You can access them from home or school via the Library Webpage or use the link below. http://www.mxcc.commnet.edu/Content/Find_Articles.asp Two short videos on the benefits of using library databases: http://www.youtube.com/watch?v=VUp1P-ubOIc http://youtu.be/Q2GMtIuaNzU Differences Between the Internet and Library Databases The Internet Library Databases Examples Google, Yahoo, Bing LexisNexis, Literary Reference Center or Health and Wellness Resource Center Review process None – anyone can add Checked for accuracy by content to the Web. publishers.
