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’. -

SQL Version Analysis
Rory McGann SQL Version Analysis Structured Query Language, or SQL, is a powerful tool for interacting with and utilizing databases through the use of relational algebra and calculus, allowing for efficient and effective manipulation and analysis of data within databases. There have been many revisions of SQL, some minor and others major, since its standardization by ANSI in 1986, and in this paper I will discuss several of the changes that led to improved usefulness of the language. In 1970, Dr. E. F. Codd published a paper in the Association of Computer Machinery titled A Relational Model of Data for Large shared Data Banks, which detailed a model for Relational database Management systems (RDBMS) [1]. In order to make use of this model, a language was needed to manage the data stored in these RDBMSs. In the early 1970’s SQL was developed by Donald Chamberlin and Raymond Boyce at IBM, accomplishing this goal. In 1986 SQL was standardized by the American National Standards Institute as SQL-86 and also by The International Organization for Standardization in 1987. The structure of SQL-86 was largely similar to SQL as we know it today with functionality being implemented though Data Manipulation Language (DML), which defines verbs such as select, insert into, update, and delete that are used to query or change the contents of a database. SQL-86 defined two ways to process a DML, direct processing where actual SQL commands are used, and embedded SQL where SQL statements are embedded within programs written in other languages. SQL-86 supported Cobol, Fortran, Pascal and PL/1. -
Sql Merge Performance on Very Large Tables

Marcel never danced stagily when Used by Google Analytics to track your activity on a website. One problem is caused by the increased number of permutations that the optimizer must consider. Much to maintain for very large tables on sql merge performance! The real issue is how to write or remove files in such a way that it does not impact current running queries that are accessing the old files. Also, the performance of the MERGE statement greatly depends on the proper indexes being used to match both the source and the target tables. This is used when the join optimizer chooses to read the tables in an inefficient order. Once a table is created, its storage policy cannot be changed. Make sure that you have indexes on the fields that are in your WHERE statements and ON conditions, primary keys are indexed by default but you can also create indexes manually if you have to. It will allow the DBA to create them on a staging table before switching in into the master table. This means the engine must follow the join order you provided on the query, which might be better than the optimized one. Should I split up the data to load iit faster or use a different structure? Are individual queries faster than joins, or: Should I try to squeeze every info I want on the client side into one SELECT statement or just use as many as seems convenient? If a dashboard uses auto refresh, make sure it refreshes no faster than the ETL processes running behind the scenes. -

An Overview of the Usage of Default Passwords (Extended Version)
An Overview of the Usage of Default Passwords (extended version) Brandon Knieriem, Xiaolu Zhang, Philip Levine, Frank Breitinger, and Ibrahim Baggili Cyber Forensics Research and Education Group (UNHcFREG) Tagliatela College of Engineering University of New Haven, West Haven CT, 06516, United States fbknie1, [email protected],fXZhang, FBreitinger, [email protected] Summary. The recent Mirai botnet attack demonstrated the danger of using default passwords and showed it is still a major problem in 2017. In this study we investigated several common applications and their pass- word policies. Specifically, we analyzed if these applications: (1) have default passwords or (2) allow the user to set a weak password (i.e., they do not properly enforce a password policy). In order to understand the developer decision to implement default passwords, we raised this question on many online platforms or contacted professionals. Default passwords are still a significant problem. 61% of applications inspected initially used a default or blank password. When changing the password, 58% allowed a blank password, 35% allowed a weak password of 1 char- acter. Key words: Default passwords, applications, usage, security 1 Introduction Security is often disregarded or perceived as optional to the average consumer which can be a drawback. For instance, in October 2016 a large section of the In- ternet came under attack. This attack was perpetuated by approximately 100,000 Internet of Things (IoT) appliances, refrigerators, and microwaves which were compromised and formed the Mirai botnet. Targets of this attack included Twit- ter, reddit and The New York Times all of which shut down for hours. -

Introduction to Database
ST. LAWRENCE HIGH SCHOOL A Jesuit Christian Minority Institution STUDY MATERIAL - 12 Subject: COMPUTER SCIENCE Class - 12 Chapter: DBMS Date: 01/08/2020 INTRODUCTION TO DATABASE What is Database? The database is a collection of inter-related data which is used to retrieve, insert and delete the data efficiently. It is also used to organize the data in the form of a table, schema, views, and reports, etc. For example: The college Database organizes the data about the admin, staff, students and faculty etc. Using the database, you can easily retrieve, insert, and delete the information. Database Management System Database management system is a software which is used to manage the database. For example: MySQL, Oracle, etc. are a very popular commercial database which is used in different applications. DBMS provides an interface to perform various operations like database creation, storing data in it, updating data, creating a table in the database and a lot more. It provides protection and security to the database. In the case of multiple users, it also maintains data consistency. DBMS allows users the following tasks: Data Definition: It is used for creation, modification, and removal of definition that defines the organization of data in the database. Data Updation: It is used for the insertion, modification, and deletion of the actual data in the database. Data Retrieval: It is used to retrieve the data from the database which can be used by applications for various purposes. User Administration: It is used for registering and monitoring users, maintain data integrity, enforcing data security, dealing with concurrency control, monitoring performance and recovering information corrupted by unexpected failure.
