Web services concepts, protocols and developmentishmecse13
Web services allow applications to communicate over the Internet through open standards and protocols. They are self-contained, modular applications that can be described, published, located, and invoked over a network, typically the Internet. Key technologies that enable web services include XML, SOAP, WSDL, and UDDI. SOAP is a messaging protocol that allows communication between applications over HTTP. WSDL describes how to access web services and what operations they perform. UDDI provides a registry for businesses to publish and discover web services.
The document introduces web services and the .NET framework. It defines a web service as a network-accessible interface that allows applications to communicate over the internet using standard protocols. It describes the key components of a web service including SOAP, WSDL, UDDI, and how they allow services to be described, discovered and accessed over a network in a standardized way. It also provides an overview of the .NET framework and how it supports web services and applications using common languages like C#.
Here are some sample web services projects to try:
- Currency conversion service: Converts between currencies using live exchange rates
- Weather service: Gets current weather conditions for a city by calling a public API
- Book search service: Searches book titles and descriptions from a database
- Calculator service: Provides basic math operations like add, subtract, multiply, divide
- Address validation service: Validates and standardizes address fields for a location
- Image processing service: Resizes, crops or applies filters to images uploaded to a server
These cover common domains like finance, data, calculation etc. and demonstrate basic CRUD operations, external API calls, file uploads etc. Good for learning core web service concepts.

Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

2. What is .NET?
Microsoft® .NET is a set of Microsoft software technologies for connecting
information, people, systems, and devices
It is a device and platform independent distributed computing model based
on Web Services (which are in turn based on open XML communication
technology), and consists of
a software platform for building .NET experiences
a programming model and tools to build and integrate XML Web services
a set of programmable XML Web services
a way to enable users to interact with a broad range of smart devices via the
Web, while ensuring that the user, rather than the application, controls the
interaction
a way to provide a user with applications, services, and devices that are
personalized, simple, consistent, and secure
.NET is all about creation, consumption and delivery of Web Services
3. What is a Web Service?
Small, reusable applications written in XML
Client to Client
- Clients can use XML Web
Services to communicate data
Client to Server
- Clients can send data to and
receive data from servers.
Server to Server
- Servers can share data with
each other.
Service to Service
- web services can work
together.
5. .NET Experience
.NET Experiences are XML web services
that allow you to access information
across the internet in an integrated way
Products transitioning into the .NET
experiences are:
MSN Website
Visual Studio .NET Website
Passport Website
6. .NET Clients
Clients are PCs, handheld computers, Tablet PCs,
game consoles (Xbox), smart phones …
All of them use XML Web Services
.NET client software includes
Windows CE
Windows XP
Windows Embedded
Windows 2000
7. .NET Services
XML Web Services
Offer a direct means for applications to interact
with other applications
First set of XML Web Services developed are
called .NET My Services (“HailStorm”)
8. .NET Servers
.NET Enterprise servers are Microsoft's
comprehensive family of server applications for
building, deploying, and managing scalable,
integrated, Web Services and applications
Designed with machine critical performance
Examples of .NET Servers:
MS Commerce Server 2000
MS Exchange Server 2000
9. .NET Tools
Microsoft Visual Studio .NET and Microsoft
.NET Framework supplies complete solution for
developers to build, deploy and run XML services
Visual Studio .NET is the next generation of
Microsoft’s popular multi-language development
tool built especially for .NET
Enhances existing languages like Visual Basic
with new OO features
Introduces C#
10. Web Services Revisited
Web services are platform independent
Encompasses Windows, Unix, Mac, Linux, even PalmOS
Web services are agnostic of the object model being used
Compatible with RPC, DCOM, CORBA, and Sun RMI
Web services are loosely coupled
Unlike tightly-coupled RPC and distributed object systems, which require all the
pieces of an application be deployed at once, you can add clients and servers to
Web-based systems as needed
Web services are built on open standards
XML, SOAP, WSDL, UDDI, HTTP, RPC
Web services are compatible with existing object models
Replaces internal "plumbing" of the network RPC wire format transparently to
user
Web services permit secure transmission
HTTPS, SSL
11. Web Services vs. Traditional Web
Applications
Web services use SOAP messages instead of
MIME messages
Browsers just need to render web pages; web
services need to do more
Web services are not HTTP-specific
SOAP messages can be sent using SMTP, raw TCP
or an instant messaging protocol like Jabber
Web services provide metadata describing the
messages they produce and consume.
XML Schema (XSD) is used to describe various
message structures
12. Extensible Markup Language
(XML)
XML is the glue that holds .NET together
XML is the defacto standard for data
interoperability.
XML provides a way to put structured data
into a form that can be easily and quickly
transmitted and then interpreted at the other
end
XML looks like HTML, and like HTML, it is
readable and text-based
XML is license-free, platform-independent,
and well supported
13. Simple Object Access Protocol
(SOAP)
“SOAP provides a simple and lightweight
mechanism for exchanging structured and
typed information between peers in a
decentralized, distributed environment
using XML “
A SOAP message is based on XML and
contains the following parts:
The Envelope is the top-level container
representing the message.
The Header is a generic container for added
features to a SOAP message. SOAP defines
attributes to indicate who should deal with a
feature and whether understanding is optional
or mandatory.
The Body is a container for mandatory
information intended for the ultimate message
receiver.
14. SOAP (cont’d)
Soap is the communications protocol for XML Web services.
SOAP is a specification that defines the XML format for messages—
and that's about it – a SOAP implementation will probably include
mechanisms for object activation and naming services but the SOAP
standard doesn't specify them
Optional parts of SOAP specification describe how to represent
program data as XML and how to use SOAP to do Remote Procedure
Calls
SOAP is much smaller and simpler to implement than many of the
previous protocols.
DCE and CORBA took years to implement, so only a few
implementations were ever released; SOAP, however, can use existing
XML Parsers and HTTP libraries to do most of the hard work, so a
SOAP implementation can be completed in a matter of months – so
several implementations for it have been released (> 70 to date).
SOAP obviously doesn't do everything that DCE or CORBA do, but the
lack of complexity in exchange for features is what makes SOAP so
readily available
15. Web Service Description Language
(WSDL)
A Web Service Description defines all the supported
methods that a Web Service provides.
WSDL is an XML grammar that developers and
development tools use to represent the capabilities and
syntax of a Web Service.
Similar to IDL for COM and CORBA
Imagine you want to start calling a SOAP method
provided by one of your business partners. WSDL
specifies what a request message must contain and
what the response message will look like in
unambiguous notation.
16. Universal Discovery Description
and Integration (UDDI)
UDDI is the yellow pages of Web Services
you can search for a company that offers the services you need, read about the
service offered and contact someone for more information
A UDDI directory entry is an XML file that describes a business and the services it
offers.
There are three parts to an entry in the UDDI directory
"white pages" describe the company offering the service: name, address, contacts, etc.
"yellow pages" include industrial categories based on standard taxonomies such as the North
American Industry Classification System and the Standard Industrial Classification.
"green pages" describe the interface to the service in enough detail for someone to write an
application to use the Web service.
UDDI defines a document format and protocol for searching and retrieving discovery
documents - which in turn link to DISCO documents.
DISCO (Discovery of Web Services) is a Microsoft protocol for retrieving the
contracts for Web Services (WDSL documents).

23. Framework Class Library
The FCL is a hierarchical class library that can be utilized across
multiple languages and platforms.
Contains reusable classes, interfaces, and components that can
be used for:
Developing components and Web Services.
Developing Windows Forms applications.
Developing Web Forms applications.
Working with Directory Services, Event Logs, Processes, Message
Queues, and Timers.
Creating and managing threads.
Managing application security.
Key features and benefits
Cross-Language Interoperability
Consistent and Unified Programming Model
Object-Oriented and Extensible Class Library
24. Common Language Runtime
The CLR is at the core of the .NET platform - the
execution engine. A unifying framework for designing,
developing, deploying, and executing distributed
components and applications.
Loads and runs code written in any runtime-aware
programming language (approx. 22 as of now).
Manages memory, thread execution, type safety
verification and garbage collection.
Performs compilation (Just In-time Compiler)
Makes use of a new common type system capable
of expressing the semantics of most modern
programming languages. The common type system
defines a standard set of types and rules for creating
new types.
Inheritance/Reference NOT dependent on source
language
25. MSIL and JIT Compilation
Source code is compiled into MSIL (Microsoft Intermediate Language).
Similar to Java bytecode.
MSIL allows for runtime type-safety and security, as well as portable
execution platforms (all Windows). MSIL code cannot play tricks with
pointers or illegal type conversions.
The MSIL architecture results in apps that run in one address space -
thus much less OS overhead.
Compilers also produce “metadata”:
Definitions of each type in your code.
Signatures of each type’s members.
Members that your code references.
Other runtime data for the CLR.
Metadata along with the MSIL enables code to be self-describing - no
need for separate type libraries, IDL, or registry entries.
When code is executed by the CLR, a JIT compilation step occurs.
Code is compiled method-by-method to native machine code.
27. Packaging: Modules, Types,
Assemblies, and the Manifest
A “module” refers to a binary, such as an EXE or
DLL.
Modules contain definitions of types, such as classes,
interfaces, structures, and enumerations.
An assembly contains a “manifest”, which is a catalog
of component metadata containing:
Assembly name.
Version (major, minor, revision, build).
Assembly file list - all files “contained” in the assembly.
Type references - mapping the managed types included in
the assembly with the files that contain them.
Scope - private or shared.
Referenced assemblies.
No MSIL code can be executed unless there is a
manifest associated with it.
28. Packaging: Modules, Types,
Assemblies, and the Manifest
An assembly can be defined as one or more modules
that make up a unit of functionality. Assemblies also
can “contain” other files that make up an application,
such as bitmaps and resource files.
An assembly is not a physical file.
An assembly is the fundamental unit of deployment,
version control, activation scoping, and security
permissions.
Two types of assemblies:
Private - Usually deployed in the same directory as the client
application and used only by a single application.
Shared - Used by any application and usually installed in a
special Global Assembly Cache.
29. .NET Component Model
Offers developers an component model directly
based on OO.
Removes distinction between a program element and
a software component. Thus it provides significant
benefits over technologies like CORBA and COM.
.Net gets rid of the IDL - we can use a .Net assembly
directly as a component.
Uses interface documentation already present in the
source code. Compliers for .Net supported languages
retain this information as metadata - self documented
components.
Metadata is also available in XML format, any
application whether it is a part of .NET or not can
obtain information about components.
30. Microsoft C#
A modern, object-oriented programming
language built from the ground up to exploit the
power of XML-based Web services on the .NET
platform.
The main design goal of C# was simplicity rather
than pure power.
Features of C#
Simplicity Type Safety
Consistency Version Control
Modernity Compatibility
Object Orientation Flexibility
31. .NET security
The .NET Security Framework Architecture consists of
the following five core elements:
Evidence Based Security - At runtime, the CLR determines
permission requests by evaluating the assembly’s evidence.
Code Access Security - allows code to be trusted to varying
degrees, depending on where the code originates and on other
aspects of the code's identity.
Verification - during JIT, the CLR ensures memory type safety.
Role Based Security - .NET applications can make
authorization decisions based on identity and role membership.
Cryptography - The .NET Framework provides Random
Number Generation and other Cryptographic services.
32. Conclusion
.Net creates a new concept, “the Internet Operating
System”.
.Net allows cross-platform development to an extent
not before possible.
.Net web services can be integrated into existing
distributed object technologies today by replacing
their RPC wire protocol with SOAP .
Large-scale distributed application development and
deployment become possible on a level that presents
major difficulties today.
Stricter versioning policies help to ensure greater
stability during upgrades, even in shared libraries.
"Software as a service" - a subscription model for
application deployment - becomes a feasible option.
