SQL is a language used to communicate with database management systems to manage data. It allows users to define databases, retrieve, insert, and modify data. SQL is easy to learn and use interactively or in programs due to its English-like statements. It is portable across systems and supports multiple views of data. SQL's success is due to its simplicity, ability to access data interactively and programmatically, support for relational databases, and portability across vendors.
The document discusses classes and methods in C#. It defines a class as a blueprint for creating objects with common properties and methods. A class declaration defines the data members (fields) and function members (methods) of the class. Methods are functions defined within a class that can access and modify the class's fields and other methods. The document covers various ways of passing parameters to methods, including value parameters, reference parameters, output parameters, and parameter arrays. It provides examples of defining classes with fields and methods, as well as invoking methods and passing parameters.
1. An array is a collection of variables of the same type that are referred to by a common name. Arrays provide a convenient way of grouping related data of the same type.
2. Arrays organize data in a way that allows for easy manipulation and sorting of elements. Declaring data as an array is more elegant than declaring many individual variables when multiple pieces of related data are involved.
3. C# supports one-dimensional and multi-dimensional arrays. Elements in arrays are accessed using an index. Arrays are zero-indexed and bounds checked to prevent errors. The Length property provides the size of the array.
This document discusses SQL security concepts including users, database objects, privileges, and how the security scheme is established. It defines users as those making requests to the database, database objects as items security can be applied to like tables and views, and privileges as actions users can perform on objects like select, insert, update, delete. The security scheme is established using GRANT and REVOKE statements to specify which users have which privileges on which database objects. Views can also be used to restrict user access to only selected data. Examples show granting and revoking privileges on different database objects for various users.
1. The document explains Ajax frameworks and functions from the Ajax Gold library. Ajax frameworks contain JavaScript functions that simplify making Ajax requests, reducing code. The getDataReturnText function uses GET to fetch text from a URL, calling a callback function on completion. getDataReturnXml similarly fetches XML. postDataReturnText uses POST to send data to a URL and receive a text response.

Refraction and dispersion of light through a prismMukesh Tekwani
This document contains 20 important theory questions about refraction and dispersion of light through a prism. Some key topics covered are:
1) The angle of deviation of light passing through a prism depends on factors like the refracting angle of the prism and the angle of incidence of light.
2) When white light passes through a prism, it disperses into its constituent colors due to the refractive index of the material being different for different wavelengths of light.
3) In the position of minimum deviation, the angles of incidence and refraction of a monochromatic light ray passing through a prism are related to the refracting angle of the prism.
This document contains important theory questions about refraction of light at a plane surface and total internal reflection. It includes 24 multiple choice and derivation questions covering topics such as Snell's law, refractive index, critical angle, total internal reflection, mirages, reflecting prisms, reversing prisms, erecting prisms, optical fibers, and their applications. The document was prepared by Mukesh N Tekwani and provides a comprehensive review of key concepts and formulas relating to the refraction and total internal reflection of light.
This document contains 10 important theory questions about spherical mirrors. It defines key terms used to describe spherical mirrors such as pole, center of curvature, radius of curvature, principal axis, aperture, principal focus, focal length and focal plane. It also derives several important relationships for spherical mirrors, including that the focal length of a concave or convex mirror of small aperture is half the radius of curvature, and the mirror formula relating the focal length to the object and image distances. Finally, it derives the magnification formula for concave mirrors and asks which type of spherical mirror is preferable for observing traffic from a car.

The document discusses the disadvantages of HTML and the advantages of using XML instead. It notes that HTML lacks structure, syntax checking, and is not suitable for data interchange or describing semantics. XML was designed to store, describe, and transport data, unlike HTML which was designed for display. XML simplifies data sharing and transport between applications since it separates data from presentation and uses plain text. It also allows for international character support and makes data more available and reusable.
