Not Only SQL (NOSQL) In this paper I will use comparisons to help distinguish what is NOSQL. We will talk about NOSQL vs SQL. Document, Graph, or Key-value and wide column Models of NOSQL. We will touch on Schema and end with a condensed comparison of SQL and NOSQL. In short, a brief overview of not only NOSQL but also its opposing and conjoining systems, and their pro’s and con’s. To really understand these comparisons, you need to have an Idea of what JavaScript and JSON are in addition to the LAMP and MEAN stacks. The term LAMP referrers to (Linux, Apache, MySQL (SQL), PHP). The LAMP stack is a common stack of open source and free languages. This stack uses Linux as the operating system Apache as the server, MQSQL as the Database and PHP…

SQL Injection An SQL Injection is the technique of inserting complete or partial SQL commands in user-supplied data fields of a web application and submitting them for execution by the database server. The SQL Injection is normally injected by attackers to compromise the security of a website, access private data and perform other unauthorized actions that a developer never anticipated. Overview Majority of businesses use website features such as contact forms, search functions, feedback…

Structured Query Language (SQL) injection attacks have been around for nearly two decades and have posed a threat to companies and government agencies around the world (SQL Injection Defense, n.d). The former head of payment security for Barclaycard, Neira Jones, states; “some 97 percent of database attacks worldwide are still due to SQL injection somewhere along the attack chain (SQL Injection Defense, n.d). A SQL injection attack can lead to an unauthorized access to database content and web…

2. D H C I J E K A B F G 4. SQL-92 was a major revision and was structured into three levels: Entry, Intermediate, and Full. SQL:1999 established the core-level conformance, which should be met before any different level of conformance is achieved; core-level conformance needs are unchanged in SQL:2008. In addition to fixes and enhancements of SQL:1999, SQL:2003 introduced a new set of SQL/XML standards, three new knowledge sorts, various new inbuilt functions, and improved methods for…

as the spreadsheets, word files and other smaller application which form one main database and this is the End-User database. It is normally used by small workstations. Oracle is one of the main database products that is used within organisations, it is also referred to as Oracle RDBMS (relational database management system). Another database product that is the Microsoft SQL (structured query language) server which is also a relational data base system management. These data bases essentially…

Access control lists, and permissions should be implied on a DBMS system to ensure the integrity of it. 42. User accounts and passwords should be protected. Permissions should be set where the lowest level of access is maintained. Ensure the use of groups is accurate. 43. Two elements of a database security plan are: procedures in the event of a security risk, and the design of the security plan. 44. The advantages of a DBMS security plan is it is dependent and designed around the DBMS system…

performance and security. In the ever-changing world of technology, there have been many clear advancements in the space of databases. Two very common databases are MySQL and MongoDB. They are similar in many ways and also very different in how they deal with data. We will look at how they execute read queries and see what those similarities and differences are. Part 1: How a MySQL query is prepared and executed. For us to understand how a SQL database differs in running queries we…

big data. To increase the performance of DBMS for big data storage needs, partitioning the data across several sites and paying big license fees for enterprise SQL DBMS might be the two possible options (Stonebraker, 2010), however they are not even without disadvantages such as inflexible data…

A unique identifier will be selected that will relate to both sets of data. The simplest way is to use the identifier CustomerID as it should guarantee that a unique number value will be given to each customer and will auto increment for new customer accounts. Once this is in place the next step is to look at all the combined accounts and check their indexes. Even though the data entered may be similar, not having the same index structures for all tables and columns will create problems when…

of Unit 8. Unit 7 True/False Questions Indicate whether the following statements are true or false on the student answer sheet. 1) A scalar function operates on one row at a time. 2) An aggregate function works on multiple rows a time. 3) Whenever you have an aggregate function in a query criteria, you must use the HAVING keyword. 4) Any column in a SELECT that contains an aggregate function, but that is not a part of the aggregate function, must be addressed in a GROUP BY…
