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.

Data is raw or a symbol or set of symbols that have minimal independent meaning and information transpires when data becomes pertinent or develops a purpose.
The first type of Big Data used in military logistics is the structured data, which is data that has been stored in the databases in an orderly manner. In military logistics, the two sources of structured data are machines and humans. Examples include GPS data, usage statistics of vehicles, ships and aircrafts, and data from medical devices. The second type of structured data is unstructured data, which is data that resides in the traditional column databases and have no clear format in storage. Examples include the mobile data, and data from satellite images about certain terrains (Sagiroglu & Sinanc, 2013).
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"
Unstructured grid can consist of any type of elements ranging from triangle, quadrilateral to tetrahedral, prism, pyramids and hexahedral.
Relational database management systems are composed of objects or relations. They are managed by operations and governed by data integrity constraints.
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...
Inconsistently storing organization data creates a lot of issues, a poor database design can cause security, integrity and normalization related issues. Majority of these issues are due to redundancy and weak data integrity and irregular storage, it is an ongoing challenge for every organization and it is important for organization and DBA to build logical, conceptual and efficient design for database. In today’s complex database systems Normalization, Data Integrity and security plays a key role. Normalization as design approach helps to minimize data redundancy and optimizes data structure by systematically and properly placing data in to appropriate groupings, a successful normalize designed follows “First Normalization Flow”, “Second Normalization Flow” and “Third Normalization flow”. Data integrity helps to increase accuracy and consistency of data over its entire life cycle, it also help keep track of database objects and ensure that each object is created, formatted and maintained properly. It is critical aspect of database design which involves “Database Structure Integrity” and “Semantic data Integrity”. Database Security is another high priority and critical issue for every organization, data breaches continue to dominate business and IT, building a secure system is as much important like Normalization and Data Integrity. Secure system helps to protect data from unauthorized users, data masking and data encryption are preferred technology used by DBA to protect data.
"Although fully searchable text could, in theory, be retrieved without much metadata in the future, it is hard to imagine how a complex or multimedia digital object that goes into storage of any kind could ever survive, let alone be discovered and used, if it were not accompanied by good metadata" (Abby Smith). Discuss Smith's assertion in the context of the contemporary information environment
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.
RDBMS remains for Relational Database Management System. RDBMS information is organized in database tables, fields, and records. Each RDBMS table comprises of database table columns. Every database table line comprises of one or more database table fields. RDBMS store the information into the accumulation of tables, which may be connected by basic fields (database table sections). RDBMS additionally give social administrators to control the information put away into the database tables. Most RDBMS use SQL as database query language
Information Retrieval is simply a field concerned with organizing information. In other terms, IR is emphasizing the range of different materials that need to be searched. Others researcher said that IR is the contrast between the strong structure and typing a database system with the lack of structure in the objects typically searched in IR. The actual process in information retrieval systems is it has to deal with incomplete or under specified information in the form of the queries issued by users. IR uses the techniques of storing and recovering and often disseminating recorded data especially through the use of a computerized system.
2) Variety: Big Data comes from various sources, so data is not of single format. Basically, data is divided as - Structured, Unstructured and Semi structured. Structured data is the data which resides within fixed field . Semi structured data is tabular, relational, categorical or meta -data. Unstructured data is text , messages, tweets or posts.
A Flat file database is a database that stores data in a single file (such as .txt or .ini). One record is held in each line of the text file with fields separated by delimiters. There is no structural relationship between the records. A list of names, CNIC number, address and phone numbers written on a piece of paper or typed using a type writer or word processor is a flat file database.
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 pretty much the entire world of computers. Databases are the most used method of storage for large multiuser funtions where the coordination between many users is necessary. This is just basically what a database is.
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.
