The stego images are tested by transmitting them and the embedded data are successfully extracted by the receiver. The main objective in this paper is to provide resistance against visual and statistical attacks as well as high capacity.

II, pp. The design phase is the most important activity in the successful building of a data warehouse. In this paper, we surveyed and evaluated the literature related to the various data warehouse design approaches on the basis of design criteria and propose a generalized object oriented conceptual design framework based on UML that meets all types of user needs.

Korth, and Sudarshan Database System Concepts pp SCCC New NoSQL solutions have been developed to manage big data. These approaches are an interesting way to build no-relational databases that can support large amounts of data.

In this work, we use conceptual data modeling CDM , based on UML class diagrams, to create a logical structure of a NoSQL database, taking account the relationships and constraints that determine how data can be stored and accessible.

An application example of this NoSQL BDD design method is realised to the case of an organization working in the e-commerce business sector. International Journal of Database Theory and Application. Hiyane, A. Benmakhlouf, A. This paper includes all the basic information about the database as a service.

The working of database as a service and the challenges it is facing are discussed with an appropriate. The structure of database in cloud computing and its working in collaboration with nodes is observed under database as a service.

This paper also will highlight the important things to note down before adopting a database as a service provides that is best amongst the other. The advantages and disadvantages of database as a service will let you to decide either to use database as a service or not. Database as a service has already been adopted by many e-commerce companies and those companies are getting benefits from this service.

Database refers to the collection of data that can be processed further to produce meaningful information.

Database Management System refers to the computer system of storing meaningless data and repossessing it. A modern database system uses real-world units and even attributes. It stores data efficiently that it becomes hassle-free to operate, repossess, and get critical information. With the help of these notes, students can understand different applications of the database system. The notes involve various SQL Query language commands like select, create, drop, alter, and so on, and integrity constraints.
