General Introduction to the Project

Welcome to the “Introduction Age” throughout th e world of computer. This is a project report on Microsoft Access, HTML and ‘C’ Language as recommended by S.E.B.A. I am very thankful to S.E.B.A. for introducing Microsoft Access, HTML and ‘C’ Language, in our syllabus. Microsoft Access allows us to store and organize information in sets of tables, which can be displayed in the form of columns and rows to look like a table or an index card. I have designed one database system “Employee Records Database System” to keep the records of  all Employees in an organization. It is computerized so that it will be easy for us to maintain the everyday records in a computerized system. All the required Tables, Queries, Forms and Reports are designed. HTML is the acronym for Hyper Text Markup Language. It is a computer language that is used for creating Web pages. It is a language for describing the structure of a document. It defines a set of common styles for Web pages. In this report I have tried to design a Web site on HTML on the topic “India Tourism” containing six web pages including the home page. I have created hyperlinks to link all those web pages so that we can easily navigate through the website. I also used all the possible HTML TAGs and ATTRIBUTEs that can be useful to develop this project. The ‘C’ complier combines the capabilities of an assembly language with the features of a high-level language and therefore it is well suited for writings both system software and business packages. Programs written in ‘C’ are efficient and fast. This is due to its variety of  data types and powerful operators. It is many times faster than BASIC. There are only 32 keywords and its strength lies in its build in functions. Several standard functions are available which can be used for developing programs. I have tried to design a program in ‘C’ Language and its flowchart and the program will give the output, when a user enters any data from the keyboard.

Introduction to M. S. Access M S Access is a RDBMS package from Microsoft. Microsoft Corporation, which is the largest producer of software in the world, in the 90’s, introduced the concept of M.S. Access, to take care of most of  our database requirements. It allows us to store and organize information in sets of tables, which can be displayed in the form of columns and rows to look like a table or an index card. What’s more it allows us to perform calculations and find for our simple statistics like totals and averages. It allows us to sort the data in any fo rm and extract the required information based on the key given by us.

Creating the Database The Database helps us to extract specific information from the MS Access. This is the best way to create Database.

Steps to create the table: 1. Select Create table by using wizard, in the Database dialog box. 2. Click on either Business or Personal, depending upon the kind of table that we want to create. 3. Scroll the ‘Sample Tables’ list. Click on the required table and see the sample fields of the chosen table in the ‘Sample Field’ list. 4. To add a field from the sample list, double click on the field name and then on ‘>’ button present on the dialog box. To include all the fields from the list, click on the ‘>>’ button. 5. To remove a field after initially including it, click on it in the rightmost list, then click on the ‘<’ button. Clicking on ‘<<’ button removes all the fields. 6. After including all the required fields in the New table, click Next. 7. Wizard asks us to name the table. It even suggests a name. We have to t ype the name and click Next. 8. A final dialog box with three main options appears. Click Finish.

Employee Table

Design View of Table 2

Department Table

Design View of Table 3

Salary Table

Query in M S Access The Query helps us to extract specific information from the database. It is like asking a question to the Access and finding fi nding out the answer.

Steps to create a query: 1. Click the Query tab in the Database window. 2. Click the New button on the Database window to olbar. 3. In the New Query dialog box, select D esign View. 4. Click OK. 5. In the Show Table dialog box that opens, select the tables we want to include in our Query, clicking Add after each. 6. After we have added all the tables we want included, click Close. 7. Double click a field in the field box in the upper portion of the select Query dialog box to add it to the query design grid. 8. The Show check boxes in the grid should be checked for all the fields that we want to display in the resulting datasheet. 9. To sort the records in the resulting datasheet, click for the Field that we want to sort and then select Ascending or Descending from the drop-down list.

Output of the Query Employee Table

Salary Query

Forms in M S Access Forms give us the interface which enables the users to view as wel as enter records easily into the tables.

The output of the forms

Employee Form

Salary Form

Reports in M S Access A Report will print our database in a format, which looks best on the paper using the printer attached to our computer. This is no doubt the quickest way of creating a Report.

The output of the reports

Employee Report

Salary Report

Utility of the created Database Creating database is probably the easiest and fastest method of creating a database where we have to fill up some information and the database is ready for us. It not only creates Tables for us but all the Forms, Reports, etc., connected with it are done too.

Introduction to HTML HTML is the acronym for Hyper Text Markup Language. It is a computer language that is used for creating Web pages. It is a language for describing the structure of a document. It defines a set of common styles for f or Web pages. Hypertext is a text stored in electronic form with cross-reference links to other pages or documents. Markup means we start with the text of our page and markup (or add) special tags around words and paragraphs. The tags indicate different parts of the page, add extra features and produce different effects when the f ile is opened in the browser. Language provides Rules and Syntax for the tags and tags. It is a scripting language, which differs completely from programming language. HTML is across platform language, i.e., HTML documents can be used on any type of computer or platform like l ike Macintosh Computer, IBM Computer, UNIX, Windows etc. HTML tags do not specify the exact font sizes, line spacing, indents etc. which are the formatting features generally used to control the appearance of a document in a word processor or publishing software .

Chichen Itza was a major focal point in the northern northern Maya lowlands lowlands from the Late Classic (c.600–900 AD) through the Terminal Classic Classic (c.800–900) (c.800–900) and into the early portion of the Early Early Postclassic period (c.900–1200). (c.900–1200). The site exhibits a multitude of architectural styles, reminiscent reminiscent of styles styles seen in in central Mexico and of the Puuc and Chenes styles of the northern Maya lowlands. lowlands. The presence of central Mexican styles was once thought to have been representative of direct migration or even conquest from central Mexico, but most contemporary interpretations view the presence of these non-Maya styles more as the result of cultural diffusion. Chichen Itza was one of the largest Maya cities and it was likely to have been one of the mythical mythical great cities, or Tollans, referred to in later Mesoamerican literature. The The city may have had the most diverse diverse population in the Maya world, a factor factor that could could have contributed contributed to the variety of of architectural architectural styles at the site. site. The ruins of Chichen Itza are federal property, and the site’s stewardship is maintained maintained by Mexico’s Mexico’s Instituto Nacional de de Antropología Antropología e Historia (National Institute of Anthropology and History). The land under the monuments monuments had been privately-owned privately-owned until 29 March 2010, when it was was purchased by the state of Yucatán. Yucatán.

Introduction to C Language C is one of the most popular computer languages of today. C was a part of the ‘Basic Combined Programming Language’ (BPCL) called B, developed in the 1960’s at Cambridge University. Since, C was developed along with the UNIX operating system; it is strongly associated with UNIX. This operating system, which was developed at Bell Laboratories, was coded almost entirely in C. Today, C is running under a number of operating systems including MS-DOS. C is a robust language whose rich set of build in functions and operators can be used to write any complex program. The C complier combines the capabilities of an assembly language with the features of a high-level language and therefore it is well suited for writings both system software and business packages. Programs written in C are efficient and fast. This is due to its variety of  data types and powerful operators. It is many times faster than BASIC. There are only 32 keywords and its strength lies in its build in functions. Several standard functions are available which can be used for developing programs. C is highly portable. This means that C programs written for one computer can be run on another with little or no modification. C language is well suited for structured programming, thus requiring the user to think of a problem in terms of function modules or block. C can extend its ability. A C program is basically a collection of functions that are supported by the C library. We can continuous add our own functions that are supported by the C library. With the availability of a large number of functions, the programming task becomes simple.

Flow Chart (Algorithm to perform bubble sort)

Source Code of the Program: “Bubble Sort using C Program” #include int main() { int array[100], n, c, d, swap; printf("Enter number of elements \n"); scanf("%d", &n); printf("Enter %d integers \n", n); for (c = 0; c < n; c++) scanf("%d", &array[c]); for (c = 0 ; c < ( n - 1 ); c++) { for (d = 0 ; d < n - c - 1; d++) { if (array[d] > array[d+1]) /* array[d+1])  /* For decreasing order use use < */  { swap = array[d]; array[d] = array[d+1]; array[d+1] = swap; } } } printf("Sorted list in ascending order: \n"); for ( c = 0 ; c < n ; c++ ) printf("%d\n", array[c]); return 0; }

Output of the program

Enter number of elements 10 Enter 10 Integers 10 5 8 12 4 9 3 7 11 2 Sorted list in ascending order: 2 3 4 5 7 8 9 10 11 12

Utility of the Program This program is useful to sort an array of elements. User can choose the quantity of numbers to enter and then enter numbers one by one of his/her choice in random order. The program will accept the numbers and print them in ascending order.

General Conclusion After a long wait here I am giving the finishing touch to my Project. During solving the topics like MS Access, HTML and Turbo ‘C’, I faced a lot of unwanted errors as well as programming errors. But owing to watchful eyes of  Mr Rajesh Singh, our Computer Teacher, I can still manage to escape f rom erroneous situation. Once again I wish to thank all of my well wishers and admires who honestly blessed me and also to the teacher of our school for their friendly behavior towards me. I am also thankful to the book that have given me a lot of inspirations and provided me with the wonderful ideas. Finally, I offer my heartiest thanks to our Computer Teacher, Mr Rajesh Singh for her guidance for completing this Project, without whom this Project would have being incomplete.
