Introduction In July 24, 2014, one crazy thing happened, especially affected all U.S. travelling people. The U.S. passport and visa database crashed! The database is used to record, approve and print visas and other related documents for global people who plan to go U.S. for travelling. All international students in U.S. should apply and receive the visa before they come to U.S. More than 50,000 applicants had to delay their travelling (Press, 2014). Today ‘Big data’ is more popular than before

to face scalability and also compares the technologies that they used to scale their business. Applications and systems have adapted and accommodated for the traffic of the millions in the heat of the moment, the moment being Cloud and its nuances. Sql being a dominant technology over the past few decades has literally constructed the way

Dheeraj Reddy Damera Student ID: 700608828 Weak Levels of Consistency in Practice The article describes about the SQL standard levels. SQL means the Standard Query Language. In SQL different types of queries are being involved and different types of operations are being performed under it. SQL often means the collection of the large number of tables. SQL Create statement is used for creating the tables. Basically create statement is used for performing any type of operation. After creating the table

• Vulnerability 1: Injection – used to attack the applications in which malicious SQL statements are inserted into an entry field for execution. o Mitigation- Keeping untrusted data separate from commands and queries. • Vulnerability 2: Broken Authentication and Session Management: User authentication credentials, session Id’s are not protected when stored by using hashing or encryption techniques. o Mitigation: Adopting strong authentication and session management controls. • Vulnerability

INTRODUCTION An object-relational database management system (ORDMS) is a DBMS that supports both relational and object-oriented functions. SQL:1999 seems like the most innovative update to the language since its induction, largely because of the adoption of object-oriented related upgrades. COLLECTION TYPES “A collection is an ordered group of elements, all of the same type.” (Oracle 2002) With this addition it became possible to use set operators which allows for a single result from two queries

Abstract For many computing systems, database technologies are an essential component. They permit data to be reserved and shared electronically and the quantity of data retained in these systems continually develops at an exponential rate. As organizations upsurge their dependence on, possibly distributed, systems of information for daily business, they develop the vulnerability to security breaches even as they get efficiency and productivity advantages. However, numerous techniques like encryption

SQL Queries to retrieve data .........................................................29-37 11.Factors that influence Physical Database Design.............................38 Introduction : Generally

millions upon millions of records be stored and queried each second. Data must be highly available and quickly retrievable. These requirements put together have given rise to new forms of database technologies collectively called “NoSQL” or “Not Only SQL”. NoSQL eschews the strict guidelines that govern the creation and function of traditional relational databases. These guidelines are put aside in order to rise to the new demands of an increasingly interconnected world. The rigorous standards and data

strength is in creating the physical design of the database. The procedural database administrator is an expert in accessing data. Procedural DBAs are responsible for procedural logic support, application code reviews, access path review and analysis, SQL rewrites, debugging, and analysis to assure optimal execution. (Mullins 1995) Along with the changing job description, administrators are facing increased demands from the corporations for which they work. Database administrators are responsible
