SQL

Firstly I will like to talk about the Microsoft SQL Server. According to Vincent (July 2010) Microsoft SQL Server is a relational database managing software developed by Microsoft. Since many years back (1989) the SQL Server has been experiencing a lot attacks. For example • SQL Injection • Denial of service • Database protocol vulnerabilities • Weak authentication • Unauthorized privilege elevation Even though there are this kind of attacks. This Microsoft SQL Server has the tools and technologies that

Keywords—database; performance; SQL; NO-SQL; I. INTRODUCTION The database means we collect data according to their types or relations and store these data in the tables in order to make further operated.  And the Database-management system is usually seen as DBMS which is software application

provide the following: • Determining the database baseline • Analysis of current system performance • Increasing RAM for 150 workstations • Un-loading and re-loading the copied CRIM database • Reorganisation of SQL Indexes • Partitioning of database across multiple spindles • Establishing SQL

SQL Server has a reputation of being the one of the most trusted relational database management system as it provides great security, reliability, and scalability features. But it is also quite complex and when the size of database grows, the response time required for a query also extends. To overcome such situations, the administrators need to perform a smooth SQL tuning which will ensure that SQL statements will run as fast as possible. There are different aspects related to the program and many

from the history of relational and XML databases. Firstly, from query perspective, it is desirable that an existing query language is extended to retrieve a new type of data, allowing information from two formats to be correlated. For instance, use SQL to query both existing relational data and new XML data. Secondly, from data management perspective, it is valuable to express existing data with a newly-defined data model and query them with the corresponding query language. For example, publish relational

A No-SQL (often interpreted as Not Only SQL) database provides a mechanism for storage and retrieval of data that is modelled in means other than the tabular relations used in relational databases. Motivations for this approach include simplicity of design, horizontal scaling and finer control over availability. What is In Memory Database? An in-memory database (IMDB; also main memory database system or MMDB or memory resident database) is a database management system that primarily relies on main

programs and the workspace required for their execution and storage. While centralization reduces duplication, the lack of duplication requires that the database be adequately backed up so that in case of failure the data can be recovered. FEATURES OF SQL SERVER (RDBMS)

and Concerns In today’s world, there is a growing amount of complexity when it comes to databases. With that growing complexity, an increasing amount of security concerns arise, such as: unauthorized access and SQL injection. SQL injection is used to attack data-driven applications. SQL injections can manipulate or destroy databases depending on its purpose. Due to the security breaches, measures are constantly put in place in order to prevent anymore from happening. This paper’s aim is to outline

DBMS: The collection of programs that manages the database structure and controls access to the data stored in the database. The DBMS serves as the intermediary between the user and the database. The database structure itself is stored as a collection of files, and the only way to access the data in those files is through the DBMS. The DBMS presents the end user (or application program) with a single, integrated view of the data in the database. The DBMS receives all application requests and translates
