Database is a collection of programs that enables users to create and maintain data. The other meaning, database some collection the related files that are usually included, concurrent referenced to one another. Good feature of a database is that data and records contains some in different files can be easily organized and save from harm in danger when using specialized database management software called a database management system (DBMS) or database manager.
A database-management system (DBMS) is a group of organized data and a set of programs have access to some data. This is a collection of related data without any doubt meaning and thus is a database. The collection data usually referred to as the database, have something information directly connected to an enterprise. The main goal of a DBMS is to provide a way to store up and save some of database information that is both well-located and useful. From data, the user known facts that can be recorded and that have trusted the meaning. For example, consider the names, telephone numbers, and addresses of the people may we know.
There are many different types of DBMSs, a variety from small systems that run on personal computers to enormous systems that run on main frames. These are some example of database applications such as mechanized library systems, automatic banker machines, flight reservation systems, and mechanized parts inventory systems.
There are many functions a Database Management System (DBMS) serves that are key components to the operation of database management. When decide to perform a DBMS in business, first we must decide what type of DBMS we want. These are the ability to update and get back the data, Support Concurrent Updates, Recovery of Data, Security, ...

...sorts of files may have an internal structure, they are still considered "unstructured" because the data they contain in order in a database.
Email is an example of unstructured data, because while the busy inbox of a corporate human resources manager might be arranged by date, time or size, if it were truly fully structured, it would also be arranged by exact subject and content, with no difference or spread which is not practical, because people do not generally speak about precisely one subject even in focused emails.
Conclusion is, structured data and unstructured data have the own characteristic and benefits. We as a user must know to handling the both of integration into a database. We as a user also must take attention in any probability in database storage.

There are two types of data. They are unstructured and multi-structured. Unstructured data comes from information that isn’t organized or easily interpreted by traditional databases or data models. This is usually in text format.
The first database systems were based on the network and hierarchical models. A database can be defined as a collection of non-redundant data which can be shared by different application systems. A database implies separation of physical storage from use of the data by an application program to achieve program/data independence. Using a database system, the user or programmer or application specialist need not know the details of how the data are stored and such details are usually "transparent" to the user. .
Databases always used to fascinate me from my under graduation with great curiosity to know how large data is managed and queried. This led me to do Masters in computer science concentrating in the field of Data Management. In the course of my study, I understood the concepts of DBMS which provides a robust and efficient way of managing and mining data. Through the courses like Database Systems (ITCS 6160), Knowledge Discovery in Databases(ITCS 6162) and Knowledge Based Systems(ITCS 6155) I gained enough theoretical and practical knowledge about the importance of proper organization of data, good techniques to build an efficient database management system and how well the data can be managed.
Non-relational databases [7] are distributed and are document-oriented just like file folders hold everything from a person’s address and phone number to their tweets online surfing preferences, in the similar manner non-relational databases keep tracks of all documents.
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.
For this coursework two kinds of data models can be used. The object oriented data model, Object Oriented Database Management System(OODBMS), or the relational data model, Relational Database Management System(RDBMS). The differences between these two models and the data model to be used are described in this chapter.
A database contains a variety of data which are structurally placed in order. They can easily be manipulated, accessed and viewed e.g. a dictionary, timetable or telephone book. A database is like a bank, were you either retrieving the money as well as storing it or you just simply view the amount.
A database is a collection of data which is organized and easy for users to find data. Database can record massive amount of data, it can be use for business and organization’s purpose. Every organization should have database security to secure the information of the organization.
A database is an ordered collection of data that usually can be accessed through many different ways. A databases most important function is retrieving information. But Databases also have many other functions pertaining to information, including being able to sort, store, and locate information. The easier a database can access information the more effective the database is. Most of todays complex databases are found on a computer.
A database management system, or DBMS, gives the user access to their data and helps them transform the data into information. Such database management systems include dBase, Paradox, IMS, and Oracle. These systems allow users to create, update, and extract information from their databases. Compared to a manual filing system, the biggest advantages to a computerized database system are speed, accuracy, and accessibility.
Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.
A database management system is a collection of programs that allow users to create and maintain a database. Even though there are numerous advantages for using database management systems, there are a few disadvantages. Such disadvantages include complexity, size, performance, and the associated costs of a database management system. The advantages of a database management system outweigh the disadvantages, but one should understand the disadvantages to ensure they have a complete understanding of the system.
Unstructured usually refers to information that doesn’t reside in a traditional row column database. As we might expect , it’s the opposite of structured data. The data stored in fields in a database. Unstructured data files often include text and multimedia content. Example include e-mail messages , word processing document , video , photos , audio files , presentations , web pages an may other kinds of business document. Note that these sorts of file may have an internal structure they are still considered unstructured because the data they cont...
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.
Another function of the DBMS is the concurrency control services. Database Management System must ensure that the database is updated correctly because the database can be used by many multiple users. The DMS enable many user to access the data concurrently. The database managements system will help from ay data loss. It have the features which that can support the updates like batch processing, locking, two-phase locking and the time stamping.
