There are many different types of databases, different performances of databases, and different database software functions. Before we get to much into databases lets take a step back and think about what a database really is and how they are applied. A database is a software program arranged to collect hold and process information. There are quite a bit of software programs out there already that can allow you to do all this. However, what makes databases different is that once you enter information in to, the database will operate the information in ways that allow you to analyze the information. Databases are designed in such a way that as to make it easier to obtain particular pieces of data. Databases are used in many ways existing in …show more content…
Whether we want to accept it not humans rely on databases they could even be called somewhat of a structure for us. In fact databases play such a large role in day to day life that just asking the question “ what would life be like without databases?” could even be the same as asking “what if computers never existed?”. Finally, we move to the last point. People as a whole are always interacting with databases. If you have ever gone to a library and could not find the book or the movie you were looking for, you turn to the computer. When you do this and you look up what you want, you are accessing the libraries database, the entire collection of everything and anything that the library has on site and even whats not there. The next example of how people interact with databases is through scheduling flights. Since we live in a modern age where pretty much everything is done online for the most part its pretty simple to understand this example. In this day and age whenever someone needs to schedule a flight they just go online to the airlines website and look at the available flights to the destination that they would like go. When doing this, you are actually accessing a database of the airlines available flights for that destination. The last example on how people interact with databases is through online shopping. In fact just last week I, myself was looking for a part for my car engine that could only be ordered online. So when I went to the website I saw an
Database tools and technologies affected the business processes and decision making by a great extent. The most important benefit of the database is to change unstructured information into structured information, and allow users to analysis the data stored into different tables with the help of queries. Before database, all the information used to stored into paper and other unstructured computer programs, due to which getting required information process was very slow. Due to database, all the
Data objects can model relational data or advanced data types such as graphics, movies, and audio. Smalltalk, C++, Java, and others are objects used in object-oriented data. The object-relational is a combination of relational and object-oriented databases. Traditional and advanced data types can be used to construct database management systems. These systems can connect to a company’s website and update records as needed. Database Approach The main purpose of a database is data storage that can be stored and retrieved when needed. A popular common language called structured query language (SQL) is used to store and retrieve data in relational database. This language enables the systems to run a report or modify data or remove the data from the database. A database management system (DBMS) controls all aspects of a database, this is not limited to the creation, maintenance, and use of database. The DBMS ensures proper applications are able to access the database. An important purpose of a DBMS is to maintain the data definitions (data dictionary) for all the data elements in the database. It also enforces data integrity and security measures. Data Models Data models provide a contextual framework and graphical representation that aid in the definition of data elements. In a relational database, the data model lays the foundation for the database and identifies important entities,
I would have the fields set up as first name (EMP_FIRST), middle initital, (EMP_INITIAL), last name (EMP_LAST), area code (EMP_AREACODE), phone (EMP_PHONE).
This must be in your own words and not copied and pasted from the original source. Include the purpose of the database and the subject matter it covers. This may be four or five sentences; and
Whatis.com (2004) defines a database as "a collection of information that is organized so that it can easily be accessed, managed, and updated." In my current job at Wellco Tank Trucks, Inc., we do not use any type of databases in the daily operations of our business. My only job that involved regular use of a database was at Chilcutt Direct Marketing (CDM) in Oklahoma City, Oklahoma. From February 2003 to June 2004, I was an Account Executive of Brokerage at CDM. CDM is a direct marketing company that manages and brokers customer mailing lists for companies across the United States.
Databases are everywhere now and impact our lives in a multitude of ways. It can accurately be said that “your life is in a database” or, more accurately, in multiple databases, and information about you (a retrieval of facts about
Figure 11 shows the relationship of a database using DBMS, connecting the user with the information from the database. A database consists of many data from customers to orders, services, employees, and so on. The user can be a customer or employee. Employees use DBMS to find customer’s information, service types, and service provider information. Later in the process, the DBMS will then extract data from the database to answer the users’ questions.
Relational database affects my daily life because I use at work all the time. I started to work as a caregiver and I have to have many fields for many occasions, for example I need to do a table for her food and have breakfast, lunch, snack, and dinner as her fields to identify what she will be her choices in having that day. Then I will have another table for her medicine that she needs to drink at a certain time. Clearly, I have used relational database daily. I also use relational database for my personal life like my data for contacts, music, and pictures, all these data have their own table set up, for example, my music, I have all the music organized by there genres, I have about 2 I only have rap music and Spanish music and when i downloaded
Example 1 – Consider the following relational database for the Super Baseball League. It keeps track of teams in the league, coaches and players on the teams, work experience of the coaches, bats belonging to each team, and which players have played on which teams. Note the following facts about this environment:
A database is a collection of data that is organized and is supposed to be organized in such a way that it resembles reality. An example is finding the amount of room on a flight, so you find one with a spare seat available. Databases are supposed to be organized in a way where in the end the users and stake holders that may not have the same knowledge of a database as you, can easily read and
Databases are normally used by businesses and schools to store their data. These databases are kept secure, and users can only access the information stored on the database they have been granted access to. Now data is added to, accessed, or remove from a database using languages such as SQL (Structured Query Language), MYSQL (My Sequel), etc.
In order to obtain peer reviewed research articles related to the impact of the psychological contract on job satisfaction in community mental health care workers it is important to review research that has been completed in a variety of researchers and in different settings. The databases that were selected to locate peer reviewed articles for this paper where Academic Search Complete and ProQuest Psychology. Tutorials were available for each of these databases and ProQuest was used to learn how to navigate through the data base since it was not a familiar data base to this author.
Databases allow us to easily store and retrieve data in a purely digital format. The strength of this is that large amounts of data can be stored and retrieved with minimal effort on the part of the user. Opposed to manually flipping through files, one can quickly pull up the requested data through a computer program. Many systems that were conventionally paper and file based have been converted to a digital format which are now stored in one or more databases.
“A database is a structured collection of records or data that is stored in a computer system. In order for a database to be truly functional, it must not only store large amounts of record, but also be able to access those records fast and efficiently. In addition, new information and changes should also be easy to input.” (tech-faq.com) To be useful over a long term the database should be able to store all the records necessary for the business to function as well as be able to get all of this information back in case of a system failure or a crash. If all the information is loss a business could go bankrupt so the database is a fail
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.
