A database management system (DBMS) is software that allows for the creation, management, and use of databases. A DBMS provides users and administrators with various tools and applications to store, organize, and access data. It allows for data to be easily retrieved, filtered, sorted, and updated efficiently. Some key components of a DBMS include the database users, the data itself, software and procedures, hardware, and database access languages. DBMSs are widely used in applications such as banking, universities, e-commerce, and more.

We presented a list of capabilities that should be provided by the DB.pdfarchanacomputers1
We presented a list of capabilities that should be provided by the DBMS software to the DBA,
database designers, and end users to help them design, administer, and use a database. Then we
gave a brief historical perspective on the evolution of database applications. We pointed out the
recent rapid growth of the amounts and types of data that must be stored in databases, and we
discussed the emergence of new systems for handling \"big data\" applications. Finally, we
discussed the overhead costs of using a DBMS and discussed some situations in which it may not
be advantageous to use one. Define the following terms: data, database, DBMS, database
system, database catalog, program-data independence, user view, DBA, end user, canned
transaction, deductive database system, persistent object, meta-data, and transaction-processing
application. What four main types of actions involve databases? Briefly discuss each. Discuss
the main characteristics of the database approach and how it differs from traditional file systems.
What are the responsibilities of the DBA and the database designers? What are the different
types of database end users? Discuss the main activities of each. Discuss the capabilities that
should be provided by a DBMS. Discuss the differences between database systems and
information retrieval systems. Identify some informal queries and update operations that you
would expect to apply to the database shown in Figure 1.2. What is the difference between
controlled and uncontrolled redundancy? Illustrate with examples. Specify all the relationships
among the records of the database shown in Figure 1.2.

Data: data is simply called as collection of objects.
Data base : data base is collection of information which is organised in so the information can be
accessed very easily.
Data base Management System: it is a computer software. it creates and manages database.it also
capture and analyses the data.
Data base System : it is a highlevel definition which relates the structure and relationship
between stored data.
Database catalog : database catalog consists of tables, views, synonyms, value ranges, indexes,
users, and user groups are stored.
program data independence: Data independence is the type of data transparency that matters for a
DBMS.
User View: It is some set screens which appears for a user to select a certain actiomn or option.
DBA: DBA refers to data base adminstrator he controls all the action with respect to data base.
End User: end user is a person he will use the product after it is developed fully.
Canned Transaction : It is a standard type of query and updates that have been carefully
programmed and tested.
deductive database: A deductive database is a database system that can make deductions (i.e.,
conclude additional facts) based on rules and facts.
Persistent objects: These are the fundamental logical units of data storage in a database.
Meta data: meta data is a data which provides the information of other .

COLLEGE BUS MANAGEMENT SYSTEM PROJECT REPORT.pdfKamal Acharya
The College Bus Management system is completely developed by Visual Basic .NET Version. The application is connect with most secured database language MS SQL Server. The application is develop by using best combination of front-end and back-end languages. The application is totally design like flat user interface. This flat user interface is more attractive user interface in 2017. The application is gives more important to the system functionality. The application is to manage the student’s details, driver’s details, bus details, bus route details, bus fees details and more. The application has only one unit for admin. The admin can manage the entire application. The admin can login into the application by using username and password of the admin. The application is develop for big and small colleges. It is more user friendly for non-computer person. Even they can easily learn how to manage the application within hours. The application is more secure by the admin. The system will give an effective output for the VB.Net and SQL Server given as input to the system. The compiled java program given as input to the system, after scanning the program will generate different reports. The application generates the report for users. The admin can view and download the report of the data. The application deliver the excel format reports. Because, excel formatted reports is very easy to understand the income and expense of the college bus. This application is mainly develop for windows operating system users. In 2017, 73% of people enterprises are using windows operating system. So the application will easily install for all the windows operating system users. The application-developed size is very low. The application consumes very low space in disk. Therefore, the user can allocate very minimum local disk space for this application.

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.
