Analyzing Database Management Systems 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. In the world of computer science large groups of data that are collected are referred to as databases. When there is a multitude of these databases, a way to manage all of this information is needed. That is where database management systems (DBMS) come into play. “A database management system is a collection of programs that enables users to create and maintain a database. The DBMS is a general-purpose software system that facilitates the processes of defining, constructing, manipulating, and sharing databases among various users and applications” [1]. Analyzing these database managements systems could potentially have huge benefits since companies could determine when and where to sell products, track certain trends, and possibly predict future outcomes. Two popular ways to analyze these large amounts of data are OLAP, online analytical processing tools and/or data mining. According to Oracle, one of the
A database administration framework (DBMS) is a PC programming application that connects with the client, different applications, and the database itself to catch and dissect information. A universally useful DBMS is intended to permit the definition, creation, questioning, upgrade, and organization of databases.
A Database Management System or (DBMS) is an essential tool for any organization or company in today’s modern world. A DBMS is “a group of programs that manipulate the database and provide an interface between the database and its users and other application programs” (Stair & Reynolds, 2011, p. 189). So in choosing the right DBMS there are many factoring issues with choosing the right one for the company or organization. When choosing a DBMS one has to think about how the system will ultimately help the company or organization with day to day processes and the goals of the company or organization.
Computer Information Systems (CIS) have forever altered the way in which organizations conduct business. No longer is commerce managed through clunky and expensive paper-based transactions. The advantage of this archaic process, though, was that it allowed corporations to store their documents in secure locations under tight lock & key. Today however, these cabinets have been replaced with database systems. Database systems are the modern version of filing cabinets, which house the vast data transacted by corporations.
There are several important steps to consider when designing a database, as a well-designed database should be deployed and not only support the accuracy and integrity of business information but also avoid redundant data and assist with has enterprise level reporting tasked. If we analyze the
A DBMS is a software program that is intended to manage and query multiple databases. A single database is comprised of tables of relational data, whereas a DBMS can manage relational data that crosses more than one database, and it serves as a manager of the interfaces between the numerous databases, allowing relationships to between databases to be formed. Database managers enhance the classic search feature in most systems to be that much more powerful and vigorous (Onh, 2009).
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.
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 has integrity when the data in it satisfies all established integrity constraints. A good DBMS should provide an opportunity for users to incorporate these integrity constraints when they design the database. The DBMS then should ensure that these constraints are not violated.
Connolly and Carolyn (2004) define a database as a structureordesign that consists of theclient’s data as well as metadata. It is also a persistent, logicallycoherentrepository of inherentlymeaningful data that is relevant to someaspects of therealworld. The database consists of data organized in a systematicway, anditallowseasy retrieval of information, analysis, updating andoutput of data. Thatdata can be in theform of graphics, scripts, reports, text, tables, andsoon. Most of thecomputerapplications are databases at their core. Manycompaniesusuallyhave a lot of data, andsotheyhavebig databases that can handlethatlargeamount of data. It is wherenothe database administratorcomes into playtopensurepropermanagement of the database sothatthe organizational data is safe from anyintrudersor data corruption (Jones, 2014). The database is whatcontrolsthedata of theentireorganization, andany tampering of the databases can culminate to the stoppage of businessoperations.
The need to store and evaluate data is a perpetually growing field in the world of information systems. From the days of using flat files to very large database management systems that store petabytes of data in real time, the practice of building information from data continues to evolve. Today, the relational data model is quite ubiquitous and is used in a plethora of information systems ranging from accounting systems, banks, retail business, and scientific usage. It is important to understand the concepts involved in data modeling for a relational database management system in order to build an effective and efficient system.
Data has always been analyzed within companies and used to help benefit the future of businesses. However, the evolution of how the data stored, combined, analyzed and used to predict the pattern and tendencies of consumers has evolved as technology has seen numerous advancements throughout the past century. In the 1900s databases began as “computer hard disks” and in 1965, after many other discoveries including voice recognition, “the US Government plans the world’s first data center to store 742 million tax returns and 175 million sets of fingerprints on magnetic tape.” The evolution of data and how it evolved into forming large databases continues in 1991 when the internet began to pop up and “digital storage became more cost effective than paper. And with the constant increase of the data supplied digitally, Hadoop was created in 2005 and from that point forward there was “14.7 Exabytes of new information are produced this year" and this number is rapidly increasing with a lot of mobile devices the people in our society have today (Marr). The evolution of the internet and then the expansion of the number of mobile devices society has access to today led data to evolve and companies now need large central Database management systems in order to run an efficient and a successful business.
It is difficult for the companies to develop and control the database. Database Management Systems help organizations to consolidate and standardize large files of data.
This paper will discuss and make comparisons on the markets top Database Management Systems (DBMS) currently available. The paper includes a table for side-by-side comparisons of feature sets and other factors required when making decisions on which DBMS to purchase and implement in a business. While this may not be a complete list of all available DBMS systems it will include important discussions on aspects required when evaluating any major application / system choice.
A database management system (DBMS) is the interface between the application programs and the database. Whenever the application program calls for a single data file (e.g. employee gross pay), the DBMS finds the item in the database under the heading ‘payroll’ and presents it to the application program so as to relieve the end user from the burden of understanding where and how the data are stored.
The make-or-buy analysis is heavily depending on the accuracy of the company’s database. Therefore, I need to make sure that I have maintained the database and updated the information correctly. Moreover, I also need to perform several analysis from numerous files in the database and required the ability to analyze a huge amount of data effectively and in a timely manner.
