XML is a markup language that structures, stores, and sends information. It allows users to define their own tags for structuring data. There are two major types of XML databases: XML-enabled databases that map XML to a traditional database, and native XML databases that use XML documents as the fundamental unit of storage. XML documents must follow rules like starting with an XML declaration, having a root element, and properly nesting elements. Common ways to query XML data include XPath and XQuery.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

2. XML
• Extensible Markup Language
• Designed to describe data and focus on what data is.
• Used to structure store and send information.
• Easy to understand and is self describing.
• XML is derived from Standard Generalized Markup
Language (SGML)
• Documents have tags giving extra information about
sections of the document
– E.g. <title> XML </title> <slide> Introduction …</slide>
• Extensible, unlike HTML
– Users can add new tags, and separately specify how the
tag should be handled for display
3. Types of XML databases
There are two major types of XML databases:
• XML-enabled: These map all XML to a
traditional database, accepting XML as input
and rendering XML as output.
• Native XML (NXD): The internal model
depends on XML and uses XML documents as
the fundamental unit of storage.
4. XML document rules
• A “well formed” XML doc has to have correct
XML syntax and they are :
– Must start with a n XML declaration to indicate
the version of XML being used as well as other
relevant attributes.
– Must have a root element.
– Must have a closing tag.
– XML tags are case sensitive.
– XML elements must be properly nested.
– XML attribute values must be quoted.

6. • Hierarchical Data Model (Tree Structure).
• Basic object in XML is XML document.
• 2 main structuring concepts are used to
construct an XML doc
– Elements : start tag and end tag.
– Attributes : additional info to describe elements.
• In the tree representation
– Internal node : complex elements.
– Leaf node : simple elements.
7. Types of XML documents
• Data-centric XML doc
– Many small data items that follow a specific structure
and hence may be extracted from a structured DB.
– Formatted as XML doc inoder to exchange or display
over web.
• Doc-centric XML doc
– Large amounts of text ie.book
– Few or no structured data elements in these doc.
• Hybrid XML doc
– Doc may contain structured or unstructured data.
8. XML vs. Relational Database
XML Database
• XML data is hierarchical
• XML data is self-describing
• XML data has inherent
ordering
• An XML database contains
collections
Relational Database
• relational data is
represented in a model of
logical relationships
• relational data is not self-
describing
• Relational data does not
have inherent ordering
• A relational database
contains tables
11. XML Document Schema
• Database schemas constrain what information
can be stored, and the data types of stored
values
• XML documents are not required to have an
associated schema
• Schemas are very important for XML data
exchange
• Two mechanisms for specifying XML schema
–Document Type Definition (DTD)
–XML Schema Definition (XSD)
12. Document Type Definition
• DTD constraints structure of XML data
– What elements can occur
– What attributes can/must an element have
– What subelements can/must occur inside each
element, and how many times.
• Limitations
– Data types in DTD are not general
– DTD has its own special syntax and thus require
special processors.
14. XML Schema Definition
• XML Schema is a more sophisticated schema
language which addresses the drawbacks of
DTDs. Supports Different data types.
• XML Schema is itself specified in XML syntax,
unlike DTDs
• XML Schema is integrated with namespaces
• XML Schema is significantly more complicated
than DTDs
15. Querying XML Data
• There are several languages used to access
XML data from XML Documents, some are:
– XPath
– Xquery (most popular)
17. XQuery
• XQuery is a general purpose query language for XML data
• XQuery is built on XPath expressions
• XQuery is derived from the quilt query language, which itself
borrows from SQL
• XQuery is supported by all database engines (IBM, Oracle,
Microsoft, etc.)
• XQuery uses FLOWR (for, let, where, order by , result)
– for SQL from
– where SQL where
– order by SQL order by
– result SQL select
– let allows temporary variables
19. Benefits of XML
• XML doc is text based
– Takes less space can be transmitted efficiently
• One XML doc can be displayed differently on
different media.
• XML doc parts can be reused.
• Easy to understand.
20. Drawbacks of XML
• Case sensitive in nature
• XML syntax are redundant or large to binary
representation of the same data.
• Users must predefine their own tags
• Linking between XML docs requires xlink
which is complex compared to hyperlinks.
