Database Management System Case Study

A Relational Database Management System (RDBMS) is a type of database management system that stores data in the form of related tables. The system does not require many assumptions about how data is related t or how it is to be extracted from the database. The database can be viewed in several forms.

The chief complaint screen will allow clinicians to enter patient’s reasons for visiting the emergency department. The chief complaint data entry screen will be used to obtain and record information from patients such as symptoms, duration of symptoms, and what major problem they are experiencing as a result of symptoms. The chief complaint data entry screen does not deals with obtaining information about chronic illness or history of family disease. Rather, the data entry screen will enable clinicians to prioritized treatment intervention based on severity of patient’s condition. Furthermore, the data capture in the chief complaint entry screen can be applied to facilitate clinical research, clinicians training, and perform quality check. The data elements in the chief complaint data entry screen will include:

There are many restrictions on the write and read operations in database management system. These restrictions show the measurable effect on the each and every transaction in the database management system and which are due to some specific operations. The transactions are not only read that data from database all the time but sometime some transaction need to delete the data items from database and create the data items into database. Such type of transactions show high impact on concurrency control. So, we are analyzing how those transaction bias the concurrency control in database management system.

A database is a system that is specialized to manage data in a computer application system. Data has many forms, such as text, digital, symbols, graphics, images and sound. The database systems are integral components of current and future command, communication, control and intelligence information systems. (Lunt, 1992, p. 253)

The DBMS has a number of advantages as compared to traditional computer file processing approach. The DBA must keep in mind these benefits or capabilities during designing databases, coordinating and monitoring the DBMS.

The paper will first define the major concepts under review before outlining the pros and cons of a database management system (DBMS) and finally give sufficiently clear arguments to enable the vice-chancellor make an informed decision on the way forward.

Relational Database Management System (RDBMS) is an engine/system based on the relational model created by Edgar F. Codd in 1970. The major distinguish of this system is the ability to use tables for data storage while maintain and enforce certain data relationship. Another aspect of this system is that allow users to insert, update, retrieve, and delete specific content or contents storage in the database. Also, RDBMS provides relational operator codes that enable the relationship between two or more entities in a database (Dangerfield & Morris,1990). These system’s characteristics can be applied on business operations improving company management of small and large amount of information from a specific department or workplace. Relational Database Management allows monitoring all information flow from that specific department

This paper will compare and contrast five different database management systems on six criteria. The database management systems (DBMS) that will be discussed are SQL Server 2000, Access, MySQL, DB2, and Oracle. The criteria that will be compared are the systems ' functionality, the requirements that must be met to run the DBMS, the expansion capabilities – if it is able to expand to handle more data over time, the types of companies that typically use each one, the normal usage of the DBMS, and the costs associated with implementing the DBMS.

Database Management System plays a vital role in most of the real world applications that require storing and retrieving data. Database Management Systems are the most reliable means to organize data. DBMS organizes data into collections from which data can be searched or updated to. There are many different forms and types of DBMS products available in the market each having their own pros and cons. The main DBMS products that are available in today’s market are Oracle 11g, Microsoft SQL Server 2012, IBM DB2 and MySQL 5.5.

Every company that manages database requires a database administration group to supervise and promise the proper usage and employment of the company’s data. The order of database administration is not well understood or universally practiced in a consistent and easily simulated manner. Implementing a DBA function in the organization requires effective planning.

There are two types of database first one is Non-Relational and second one is Relational. Non-relation where all data is stored in one single table and relational database contain two or more table where all the data is stored in many table and table link together. A database is set the data that is stored in tables, which is also structured through objects and data is organized in fields. Databases can store large amounts of data easily because it stored hard drive; it is easy to search the database when you sort up the data. The database has many objects for example table, form, queries and report. Queries allow to easily searching the data. However database is difficult for non-technical users, also it cost for their database package and when they want to update the data they need technical knowledge. To make a database for this type to having the records of on a computer and computer makes the whole system for you more professional and also the database is easy to use and multiple purposes. There are many use of database they can help company and organization with their activities.

In Nowadays, there are two major of database management systems which are use to deal with data, the first one called Relational Database Management System (RDBMS) which is the traditional relational databases, it deals with structured data and have been popular since decades since 1970, while the second one called Not only Structure Query Language databases (NoSQL), they are dealing with semi-structured and unstructured data; the NoSQL types are gaining their popularity with the development of the internet and the social media since April 2009. NoSQL are intending to override the cons of RDBMs, such as fixed schemas, JOIN operations and handling the scalability problems. In this paper we will review one of the graph database (Neo4j), which the graph database is part of the emerging technology that is called NoSQL and compared it with one of the traditional relational database (MySQL). MySQL, it is being another name for Relational Databases and it has been used for a long period time until now. However, with the emergence of Big Data there was clearly a need for more flexible databases. Facebook 's Graph Search using Neo4j, a graph database, is an application which clearly displays how relationships need to be modeled in a more efficient and sophisticated manner than using conventional relational models. In this paper, we will make a compare between MySQL and Neo4j based on the features like ACID, replication, availability and the language that is used in both of

When selecting a new database management system, determine if the vendor offers auditing, reporting and data management tools. In addition, the software should provide application level security and interface to the organization 's corporate-wide procedures for granting access to systems. For example, authentication should allow a secure protocol, such as Secure Sockets Layer (SSL). In addition, data may need to be encrypted to ensure additional protection. Application security gateways and database firewalls understand the application and track user access. Deep packet inspection examines each packet going over the network to the database server to determine the type of access being attempted. Application security gateways can provide

As mentioned briefly above, there are different database technologies. Each technology offers its own pros and cons and below is a look at of the most common technologies.

What is database management system? Database Management System is a database program. The DBMS manage incoming data, organize it, and provided ways for the data to be modified or extract by users or other programs. This cause, most database software comes with an Open Database Connectivity (ODBC) driver that allows the database to integrate with other databases. For example, common SQL statements such as SELECT and INSERT are translated from a program's proprietary syntax into a syntax other databases can understand. Some DBMS examples include PostgreSQL, MySQL, SQL Server, Microsoft Access, Oracle, FileMaker, RDBMS, dBASE, Clipper, and FoxPro. It is a software system that uses a standard method of retrieving, and running queries on data.
