Relational database

on NoSQL database and relational database. (Under the direction of DR. JIANPING FAN) NoSQL database, also called as not only SQL database, is using a different data storage and retrieval mechanism from the relational tables adopted by traditional relational database management system. In the sense of CAP (Consistency, availability and tolerance) theorem, NoSQL database sacrifices some consistency features to get more availabilities and partition tolerances. In most cases, NoSQL database systems

NoSQL was created in the response to relational databases not being able to handle the scale and changing challenges of modern applications, they also cannot take advantage of the cheap, easy storage abilities and also the processing power accessible now. NoSQL includes a variety of different technologies that were developed in response to the surge of data stored by users, objects and products. They were also developed to contend with the rising frequency that the data is accessed and the performance

Relational databases are the most prevalent in today’s database needs for numerous different applications. These databases go by specific rules and adding in a lot of different attributes involves complexity to the system. Especially in the web applications, it gets harder for the relational databases to handle the capacities and possibilities. The web domain thus, becomes the main motivator for NoSQL. Some of the challenges faced by relational databases were the mismatch that resulted when transforming

Introduction Relational Database was proposed by Edgar Codd around the time 1969.It has become dominant for commercial applications. In the 20th century there are countless Relational Database System (RDBMS) take for instance: IBM.DB2 and Oracle. Glossary The following are the main terms and concepts related to the named model: 1. Attributes –they describe the facts, details or characteristics of an entity. The attributes that maybe contained in an invoice might be price, number, data or paid/unpaid

Advantages of a Relational Database The relational database provides a number of advantages over previous models, such as the following. • Built-in multilevel integrity: Data integrity is built into the model at the field level to ensure the accuracy of the data; at the table level to ensure that records are not duplicated and to detect missing primary key values; at the relationship level to ensure that the relationship between a pair of tables is valid; and at the business level to ensure that

Abstract. In this report I will introduce the Memcached technology and provide more details about it. In addition, I will explain how it works and how it differs than relational database technology. Furthermore, I will use the finding of the paper “Performance Evaluation of a Clustered Memcached” to present how Memcached can improve the performance of the web applications. The paper that I did study is about a simulation project of using three different architectures of Memcached. The simulation

developers go to for all data. You need only a relational database. This is the false assumption that you will see when it comes to database models. The relational database model is great for data that normally can fit into a table, or shows relationships between data, but not all data falls into that category. There are a few options for these situations. You can use an object-oriented database, a hierarchical database, a network database, and a flat-file database. The first alternative is known as the

Database Normalization Srikanth Karra Instructor: Dr. Steven Case Southern New Hampshire University When we design a database for a relational system, the main objective in the development of a logical data model is to create an accurate representation of the data its relationship and constraints. The data should be split in different tables, which can then be joined together based on their relations with each other and the data found in each one of them. These tables should therefore be designed
