Abstract
"Throughout your career, you will be directly or indirectly accessing a variety of databases, ranging from a simple roster of departmental employees to a fully integrated corporate database. You will probably access these databases using software called a database management system (DBMS). A DBMS consists of a group of programs that manipulate the database and provide an interface between the database and the user of the database and other application programs. A database, a DBMS, and the application programs that use the data in the database make up a database environment. Understanding basic database system concepts can enhance your ability to use the power of a computerized database system to support organizational goals and advance your career."
Microsoft Access
"First of all you need to understand how Microsoft Access breaks down a database. Some keywords involved in this process are: Database File, Table, Record, Field, Data-type."
"After you've set up multiple tables in your Microsoft Access database, you need a way of telling Access how to bring that information back together again. The first step in this process is to define relationships between your tables. After you've done that, you can create queries, forms, and reports to display information from several tables at once. A relationship works by matching data in key fields - usually a field with the same name in both tables. In most cases, these matching fields are the primary key from one table, which provides a unique identifier for each record, and a foreign key in the other table."
"A form is nothing more than a graphical representation of a table. You can add, update, delete records in your table by using a form. NOTE: Although a form can be named different from a table, they both still manipulate the same information and the same exact data. Hence, if you change a record in a form, it will be changed in the table also."
"A form is very good to use when you have numerous fields in a table. This way you can see all the fields in one screen, whereas if you were in the table view (datasheet) you would have to keep scrolling to get the field you desire."
"A report is an effective way to present your data in a printed format. Because you have control over the size and appearance of everything on a report, you can display the information the way you want to see it.
form. This will give me a good set of results, if I was to use
Publication of a Written Report. After a committee votes on a reported bill, the chairman instructs the staff to put together a written report.
A database is a structured collection of data. Data refers to the characteristics of people, things, and events. Oracle stores each data item in its own field. For example, a person's first name, date of birth, and their postal code are each stored in separate fields. The name of a field usually reflects...
Pivot tables are a powerful feature in Excel. It allows you to sort large amounts of data easily and allows for certain distinction in what is pulled and sorted. I currently use pivot tables daily with my job and have used them in my past work experiences. They ability to sort data is vital; it allows you so many different options for how you can display important information in your
Did you know PivotTable report also known as a PivotTable can be used to analyze and summarize large information of data without the use of formulas? In Chapter 7, a pivot table report shows the same data in a table in more than one arrangement (Marks, 2011). PivotTables can be used in numerous ways to move; pivot, and fields of data from one place to another using drag and drop. There are several of ways you can look at the same data in a number of different ways. For example, from a list of cops in a police station, you can get a quick estimation of how many calls they received. It is useful when you want to analyze related totals, like the list of numbers to sum and compare facts about different total. There are seven types of screen elements: pivot table field list, report filter area, column labels area, row labels area, values area, layout section, and field section. Several of people may believe there are several of ways to place the data from your...
For example, each row of a spreadsheet may store information about a car that Sutton Dealership will sell. Each column may store a different aspect of the car's information, such as model, make, colour, engine size, etc. The spreadsheet software can analyse this data by counting the number of people who purchased car with 2.0 litre engine size, listing all the people who purchased white cars, or performing other calculations. This makes spreadsheets similar to database.

Big Data is a term used to refer to extremely large and complex data sets that have grown beyond the ability to manage and analyse them with traditional data processing tools. However, Big Data contains a lot of valuable information which if extracted successfully, it will help a lot for business, scientific research, to predict the upcoming epidemic and even determining traffic conditions in real time. Therefore, these data must be collected, organized, storage, search, sharing in a different way than usual. In this article, invite you and learn about Big Data, methods people use to exploit it and how it helps our life.
DBA deals with all of this by finding user needs, set the database, and test the system. DBA should enable editing any system he or she created. At the same time DBA should ensure the security of the data and guarantee data integrity and backup. Moreover, DBAs should know the database management systems (DBMS) that include the knowledge of Oracle, IBM DB2, and Microsoft SQL server (“Database Administrator,” 2010). Oracle is one of the most important platforms that DBA must know and have experience with. According to Kanaracus “The database experience we look for most of the time is Oracle”, says Tom Hart, executive vice president of the operations and technology group at Veritude. “SQL Server is more of a nice-to-have"
Big data is a concept that has been misunderstood therefore I will be writing this paper with the intentions of thoroughly discussing this technological concept and all its dimensions with regard to what constitutes big data and how the term came about. The rapid innovations in Information Technology have brought about the realisation of big data. The concept of big data is complex and has different connotations but I intend to clarify its functions. Big data refers to the concept of a collection of large and complex amounts of data that are found extremely difficult to notate or even process by most on-hand devices and database technologies.

In the Orlando office we have three main databases. We have a Microsoft Access Database, a Visual Source Safe database, and a Microsoft SQL server database with a custom web client front end. The Microsoft Access database is fairly simple. We use this data base to keep track of the computer hardware and software configurations that are used when doing quality assurance testing and problem replication and troubleshooting of the software product. For any one product we can have up to twenty or thirty different configurations. Initially keeping track of the configurations along with the machine name and IP address was done on paper with a grid like matrix. After a short period of time, this became extremely time consuming and impractical. A simple database was set up in Access and then the database was shared to allow each user to be able to find out what configuration each computer was in for that day or that week so that the proper tests and or bug reporting could be conducted. The database allows the users to search by software version, platform type, operating system, machine name, IP address, memory size, and several other items that are not as significant. Before the database was created the engineer would have to leave their desk find the chart and to a cross reference using the matrix that was drawn up, and hopefully that matrix was kept up to date. Now as the technicians update or change the machine configurations they can enter that information immediately into the database and it will automatically provide a matrix view or a tabular view for any engineer who needs it.
The database application design can be improved in a number of ways as described below:
The DBMS has a function that can be differentiate from the information retrieval system. The DBMS have the ability to store, update and retrieve the data. This is the main function of the DBMS because the database can be used if there is any record is being stored into the database. The record need to be retrieve first, then it can be change by the database administrator as it will be the record has been updated. The DBMS will protect the structure of the data structure.
In our world, people rely heavily on the power of technology every day. Kids are learning how to operate an iPad before they can even say their first word. School assignments have become virtual, making it possible to do anywhere in the world. We can receive information from across the world in less than a second with the touch of a button. Technology is a big part of our lives, and without it life just becomes a lot harder. Just like our phones have such an importance to us in our daily lives, database management systems are the same for businesses. Without this important software, it would be almost impossible for companies to complete simple daily tasks with such ease.
