The document discusses how to create and manage database tables using data definition language (DDL) statements in Oracle. It covers:
- The main database objects like tables, views, sequences, indexes and synonyms
- Rules for naming tables and columns
- The CREATE TABLE statement and options for specifying columns, data types, constraints, and default values
- Types of constraints like NOT NULL, UNIQUE, PRIMARY KEY, FOREIGN KEY and CHECK
- Techniques for creating tables like using subqueries and the ALTER TABLE statement

DDL. data defination language for creating databaseSHAKIR325211
data defination language database management systems how to create a databse how to insert a record and how to select a particular coloums and fields for instance select records from employee database or select fields of particular coloumns in database than wright query Similarly, the meaning of a query in database management is a request for data . If you need to access, manipulate, delete, or retrieve data from your relational database, you'll need a database query written using a specific syntax. Our SQL tutorial will teach you how to use SQL in: MySQL, SQL Server, MS Access, Oracle, Sybase, Informix, Postgres, and other database systems.If you are adding values for all the columns of the table, you do not need to specify the column names in the SQL query. However, make sure the order of the values is in the same order as the columns in the table. Here, the INSERT INTO syntax would be as follows and somany features in database management systms Data is a collection of a distinct small unit of information. It can be used in a variety of forms like text, numbers, media, bytes, etc. it can be stored in pieces of paper or electronic memory, etc.
Word 'Data' is originated from the word 'datum' that means 'single piece of information.' It is plural of the word datum.
In computing, Data is information that can be translated into a form for efficient movement and processing. Data is interchangeable. You can organize data into tables, rows, columns, and index it to make it easier to find relevant information.
Database handlers create a database in such a way that only one set of software program provides access of data to all the users.
The main purpose of the database is to operate a large amount of information by storing, retrieving, and managing data.
There are many dynamic websites on the World Wide Web nowadays which are handled through databases. For example, a model that checks the availability of rooms in a hotel. It is an example of a dynamic website that uses a database.
There are many databases available like MySQL, Sybase, Oracle, MongoDB, Informix, PostgreSQL, SQL Server, etc.
Modern databases are managed by the database management system (DBMS). 1968 was the year when File-Based database were introduced. In file-based databases, data was maintained in a flat file. Though files have many advantages, there are several limitations.
One of the major advantages is that the file system has various access methods, e.g., sequential, indexed, and random.
It requires extensive programming in a third-generation language such as COBOL, BASIC.Cloud database facilitates you to store, manage, and retrieve their structured, unstructured data via a cloud platform. This data is accessible over the Internet. Cloud databases are also called a database as service (DBaaS) because they are offered as a managed service.A NoSQL database is an approach to design such databases that can accommodate a wide variety of data models. NoSQL can handle an exte

Les03 Single Row Functions in Oracle and SQL.pptDrZeeshanBhatti
Functions make the basic query block more powerful and are used to manipulate data values. This is the first of two lessons that explore functions. It focuses on single-row character, number, and date functions, as well as those functions that convert data from one type to another, for example, character data to numeric data.
SQL stands for Structured Query Language
SQL lets you access and manipulate databases
SQL became a standard of the American National Standards Institute (ANSI) in 1986, and of the International Organization for Standardization (ISO) in 1987
0x01 - Newton's Third Law: Static vs. Dynamic AbusersOWASP Beja
f you offer a service on the web, odds are that someone will abuse it. Be it an API, a SaaS, a PaaS, or even a static website, someone somewhere will try to figure out a way to use it to their own needs. In this talk we'll compare measures that are effective against static attackers and how to battle a dynamic attacker who adapts to your counter-measures.
