An Analysis Of The Strengths And Weaknesses Of The Big Six Database Servers

A relational database is a database that consists of a collection of tables with columns showing entities, and rows showing data. This type of database uses a primary key and foreign key. The foreign key in another table will point to the primary key of a table, and this is how tables can relate to each other. This permits for one-to-one, one-to-many, and many-to-many relationship between the data. An advantage of relational databases includes the ease of adding or modifying new tables and entities without needing to change the structure of the database already in place. Relational database have many features, including indexing, setting data type, and setting validation tests, all these help to ensure data integrity.

When it comes to customers, the use of relational database management systems can help in linking various features of business electronically, like connecting a customer with specific product

Oracle provides a flexible RDBMS called Oracle7. Using its features, you can store and manage data with all the advantages of a relational structure plus PL/SQL, an engine that provides you with the ability to store and execute program units. The server offers the options of retrieving data based on optimization techniques. It includes security features that control how a database is accessed and used. Other features include consistency and protection of data through locking mechanisms.

Many RDBMS programs also provide the tools you need to create end-user applications that interact with the data stored in the database. Of course, the quality of an RDBMS is a direct function of the extent to which it supports the relational database model. Even among “true” RDBMSs, support for the relational database varies among vendors, and there is yet to be a full implementation of the relational model’s potential. Despite this, all RDBMS programs continue to evolve and become more full-featured and powerful than ever

A unique database model is implemented by each database depending upon the logical structure of the data that is being handled by that database. There are numerous distinct database models out in the market at present that allow the application developers to effectively manage the data. The most widely welcomed

Relational Database System includes Oracle Database, Microsoft SQL Server, IBM DB2, mySQL, IBM DB2, SAP Sybase Adaptive Server Enterprise, and Teradata, etc.

The relational database does have some drawbacks. For example, it may take more time to search for data than some other methods (Heberling, 2008). The relational database would not be the best option if the application used with the database required a special data topology (Stephens, 2009). Suri and Sharma (2011) found that, though the relational database has

An object-relational database management system (ORDMS) is a DBMS that supports both relational and object-oriented functions. SQL:1999 seems like the most innovative update to the language since its induction, largely because of the adoption of object-oriented related upgrades.

Data. It is all around every person on this earth whether they realize it or not. Throughout each and everyone’s life they collect data and have their data collected by others. Height, weight, shopping habits, health history are all examples of data that is tracked. The question is what is done with this data? People, companies, even the government analyze the data they collect and analyze it with hope of discovering new information. How they do this is particularly interesting and opens the door for a larger discussion.

A database could be as simple as an alphabetical arrangement of names in an address book or as complex as a database that provides information in a combination of formats. For example a library can be considered a database because a library stores books therefore it is a database of books. But computer databases collect information and organize such to enable efficient retrieval in formats such as electronically, graphically, audibly, statistically or physically; printed on paper.

The RDBMS is so widely used because of its simplicity to understand relationships between data. The data can also be analyzed in many ways using queries, reports, etc. A database management system covers all functions of the business and is essential for businesses to be run efficiently. Since the introduction of this time of database management system in 1970 it has triumphed many former types of widely used databases and fended off new types of databases to remain the most common type.

The terms data and Internet are connected with one device and its call “Computer”. Now a day’s people are taking more interest regarding data and related terms. In general database means a collection of information that is organized so that it can easily be managed, access and update. In General, databases can be classified according to types of content: bibliographic, full-text, numeric, and pictures. Whereas, Internet play an important role in today’s world. The meaning of INTERNET means an electronic communications network that connects computer networks and organizational computer facilities around the world. Internet is connected with two different part called intra and net. Moreover, it includes business, instructive, administrative, and other networks, all of which utilize the same arrangement of interchanges conventions.

.In this paper we will examine the key features of the database management system MongoDB. Day-to-day information is growing in gigantic amount. Generated information include predominant information and it will have to be analyzed for gathering essential expertise. On the whole, relational databases are used so as to system the data. These, ways works successfully for small amount of knowledge. What if the data is very tremendous? To avoid this problems Mongo databases are introduced. MongoDB is a cross-platform document-oriented database. Classified as a NoSQL databases. NoSQL meets the requirements of the large-scale distributed computing environment, which provides scalability, high availability, high performance and reliability. NoSQL databases are increasingly used in big data and real-time web applications. Using NoSQL provides the benefit of storing data in schema less structure. NoSQL is not a brand new database technology; yet, it provides the possibility and flexibility of handling complex semi-structured data and optimizes solutions to different types of data in this massive and data-intensive era of large-scale computing.

One of the most popularly used database models is the relational model. It was developed by Edgar Codd in 1969. This model provides a declarative method for specification of data and queries. In a relational model of a database, the database users directly state the information they want to be retrieved from it and abstract away from the responsibility of describing the data structures that are used to store data. A database that confirms to the relational database model is known as a relational database.
