Growth in this occupation will be driven by the increased data needs of companies in all sectors of the economy”(1). The 11 percent might not seem like a lot compared to the specific field but if you really…
Storage Systems for Big Data Internet age comes with the vast amount of data that requires efficient storage and processing capabilities. To alleviate this issue, we discuss data storage systems which are tailored to store and process big data effectively. While general-purpose RDBMSs are still viable option in handling and analyzing structural data, they suffer from a variety of problems including performance and scalability issues when it comes to big data. To increase the performance of DBMS…
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…
Hierarchal Database “In the network model, the data are represented by collections of records and relationships between data are represented by links. This structure holds for the hierarchical model as well. The only difference is that, in the hierarchical model, records are organized as collections of trees, rather than as arbitrary graphs.”(http://codex.cs.yale.edu/avi/db-book/db6/appendices-dir/e.pdf, 17-10-2014) This database model use rules as each child has one parent and each parent can…

Homework #1 1. The search term I used is “database security” because I am interested in it when I read through it. Moreover, I want to know more about the term “database”, and it found it means a controlled collection of data, and metadata, stored on computer. I also want to learn about ways to protect against threats that specifically target databases. Besides, I searched about “Relational Databases” because most databases are relational database, and they store their data in relation. 2. I…
The Relational Database Framework The collection of information provides access to the network of the data-processing system. The representation consists vital information of real-time events. The objective requires managing personal cognizant comportment for integrating vital information. The standard utilizer and application (APP) program interface to a relational database is the Structured Query Language (SQL) (Codd, 2003-2016). The APP retrieves and supplies the information from the graph…
