SQL - Structured query language introductionSmriti Jain
SQL is a language used to define, manipulate, and control relational databases. It has four main components: DDL for defining schemas; DML for manipulating data within schemas; DCL for controlling access privileges; and DQL for querying data. Some key SQL concepts covered include data definition using CREATE, ALTER, DROP statements; data manipulation using SELECT, INSERT, UPDATE, DELETE; and joining data across tables using conditions. Advanced topics include views, aggregation, subqueries, and modifying databases.
The document provides an introduction to SQL and relational databases. It describes how relational databases organize data into tables with rows and columns, and how primary keys and foreign keys link related data across multiple tables. It introduces SQL as a non-procedural language used to communicate with the database management system to query, insert, update and delete data from relational databases in a simple English-like syntax.
SQL is a standard language for accessing and manipulating databases. It allows users to retrieve, insert, update, and delete data as well as create, modify and delete tables. The main SQL commands are grouped into four categories: data definition language for creating/modifying database structures, data manipulation language for interacting with data, transaction control language for managing transactions, and data control language for security. Common SQL commands include CREATE, SELECT, INSERT, UPDATE, DELETE, ALTER, and DROP.
SQL is a special-purpose programming language designed to manage data in relational database management systems (RDBMS). It allows users to define, manipulate, and control access to data in databases. SQL statements are divided into two main categories: DDL (Data Definition Language) statements are used to define database objects like tables, while DML (Data Manipulation Language) statements are used to query and manipulate data like SELECT, INSERT, UPDATE, DELETE. SQL was developed in the 1970s by IBM researchers Donald D. Chamberlin and Raymond F. Boyce and was initially called SEQUEL.
This document provides an agenda for an introductory course on T-SQL. The course will cover topics such as null values, distinct, having vs where clauses, data types, creating and modifying tables, joins, subqueries, functions, errors, variables, control flow and stored procedures. It provides background that SQL was first introduced in 1970 and was developed by Donald Chamberlin and Raymond Boyce at IBM as SEQUEL, later changed to SQL. The next session will cover writing basic queries.
A database is a collection of organized data that can be manipulated and accessed using DBMS. DBMS allows users to interact with databases through data definition, update, retrieval, and administration functions. Some key points covered include that Edgar Codd proposed the relational database model, SQL is the standard language for accessing and updating databases, and normalization organizes data to reduce redundancy and inconsistencies.
This document provides an introduction to database management systems (DBMS) and MySQL. It defines a database as a collection of organized information that can be quickly accessed by a computer program. A DBMS helps create and manage databases, similar to how MS Word helps create documents. The document discusses the entity-relationship model and how entities are represented as tables with attributes as columns. It provides examples of creating tables, adding primary keys, and linking tables with foreign keys. It also explains the three types of SQL statements - DDL for defining the database structure, DML for managing data, and DCL for controlling access. Specific DDL, DML, and DCL commands are defined along with syntax examples.
The document discusses using <div> tags and CSS for page layout instead of tables. <div> tags define sections of an HTML document and are easy to style with CSS. CSS properties like float allow elements to be positioned and other elements to flow around them. A common layout uses <div> tags for the logo, navigation, and main content sections.
The document discusses creating a page called tour_details.php that joins information from two tables and adds recordset paging. It provides instructions on opening a template, making changes to display data from a recordset using bindings in a repeat region showing 5 records at a time, and adding links and a dynamic image. It also discusses adding a recordset navigation bar and fixing the tourprice.php page to include a dynamic dropdown list populated from a query.

Web services allow programs to call methods on other computers over a network. They are frequently web APIs that can be accessed remotely and executed on another system. Web services consist of method information describing the method being called and scoping information describing required arguments. This information is packaged and sent across the network using various protocols like HTTP, SOAP, and XML-RPC. The internet protocol stack, consisting of layers like application, transport, network and link, is used to break information into packets that can travel over the network to their destination and be reassembled.

The document compares differences between SQL Server and PostgreSQL, cross joins and full outer joins, SQL Server and Oracle, views and stored procedures, and IN and EXISTS clauses. Some key differences include:
- PostgreSQL uses COPY instead of BULK INSERT and defaults to a different listening port than SQL Server
- A cross join returns all row combinations while a full outer join returns all rows from both tables with NULLs for unmatched fields
- SQL Server and Oracle have different default users, data types, and query plan reading directions
- Views allow single SELECT queries while stored procedures support multiple statements and parameterization
- IN checks for value matches in a subquery while EXISTS only checks if the subquery returns any rows
This document discusses SQL, including an introduction to its history and purpose. It describes common SQL data types like CHAR, DECIMAL, INTEGER, and FLOAT.

This document provides tutorials on database design and functional dependency diagrams. It includes examples of database schemas for shop, flower, and purchase product databases. It then discusses drawing functional dependency diagrams for different tables and business rules. It provides exercises to draw FDDs for personnel, shoe sales, and various order and business forms.
This document provides examples and explanations to help understand database design and entity-relationship diagrams (ERDs). It discusses which examples represent entities and relationships, and provides situations to model with ERDs involving airlines, publishers, orders, students, cars, books, accounts, drivers, projects, deliveries, subjects, and teachers. The document aims to help identify entities, relationships, and draw ERDs with cardinality constraints to represent different scenarios.
The document discusses entity-relationship modeling and database design. It identifies the key concepts of entities, attributes, relationships, and weak versus strong entities. It then outlines the step-by-step method for developing an entity-relationship model, including searching for strong entities and attributes, identifying relationships, and handling weak entities.
This document provides an overview of database design and relational database concepts. It defines key terms like data, relations, attributes, domains, tuples, functional dependencies, and network diagrams. It explains that a relational database stores data in related tables and uses primary and foreign keys to link tables based on common attributes. Functional dependency diagrams can represent relationships in a database design and be used to normalize relations into tables without redundant data.
The personnel database contains information about employees (EMPLOYEE), their expertise (EXPERTISE), prior jobs (PRIOR_JOB), current projects (ASSIGNMENT), and projects (PROJECT). The tables are related to each other through employee numbers (E_NUMBER) which act as primary and foreign keys that enforce referential integrity constraints.
The document provides tutorials on database design concepts including:
1. Writing database schemas and network diagrams for sample databases including a shop, flower, and purchase databases.
2. Drawing functional dependency diagrams for tables and business rules involving entities like orders, grades, car prices, and more.
3. Identifying entity types and relationships for an airline database about flights, pilots, and crew and a publisher database about authors, books, editors, and printers.
This document discusses key concepts in relational database design including:
- Relations (tables), attributes (columns), tuples (rows), domains, keys, and relationships between relations represented by foreign and primary keys.
- Referential integrity constraints require values in one relation's column to appear in another's column.
- Network diagrams can represent relationships between relations using arrows from foreign to primary keys.
This document provides guidance on further developing an FDD (Functional Data Diagram) for a database on shoe sales. It describes that shoes have styles identified by numbers and come in various sizes. Weekly sales and monthly sales values are recorded for each style and size combination. The FDD could be expanded to include the week and month attributes to track historical sales data over time. Forms are also provided on different entities like customer orders, software companies, fashion distributors, and music stores for which FDDs and network diagrams should be drawn.
1. This document provides instructions for setting a password in WAMPS (Wamp Apache MySQL PHP SQLite).
2. It involves editing the privileges for the default "root" user in phpMyAdmin to add a password, and then modifying the config.inc.php file to change authentication and add a secret passphrase.
3. The instructions conclude by restarting the wamp server and logging into phpMyAdmin with the new password.
