What is a database management system? Discuss each of the five important software components of a database management system.
Data Base Managements System (DBMS) is a computer software program installed on a system hard drive that catalog, retrieve, and run queries on data. It provides ways for data to be altered or removed by users or other programs. There are several different types of database management systems that exist that were created for the proper control of databases for specific purposes.
The five software components of a database managements system are DBMS engine, data definition subsystem, data manipulation subsystem, applications generation subsystem, and data administration subsystem (Cummings, 2010).
Database management systems engine is the central component of the DBMS it stores and retrieves data it accepts logical request from multiple other subsystems and transform them into its physical equivalent. The DBMS engine collects logical requests for data users and issues physical input/output requests to the computer operating system. The data requested is gathered from physical storage and while the data remains in memory, it is managed by the DBMS engine.
Data definition subsystems create and maintain data dictionary. Define structure of the files within the Data Base. Its logical structure must be defined prior to entering information and any time information is entered or deleted the data definition subsystem must be used. Field name, type, form, default value, validation rule, is an entry required, and can there be duplicates are examples of logical properties (Cummings, 2010).
Data Manipulation Subsystem is used to add, change and delete information in a database. There is software in the ...

Some examples is nanotube which is have been added to the frames of tennis racquets and gulf clubs. Nanotubes are some of the toughest materials known to exist to man. Since these tubes are microscopic, millions can be added to the tennis racquet to make it strong in order to give tennis players more control and power. Medicine is another area in which nanotechnology transforming. With the medical field dealing with things on the smallest level, the small nano devices are being developed to enter the body. An example is Nano robot which is a computer-controlled robotic device used to treat and eradicate diseases.
Nanotechnology differ from traditional manufacturing in which traditional manufacture take a large item and break it down to its smallest form, nanotechnology starts at the smallest form and build up (Cummings, 2010).

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.
One of this is in the medicine field. A Nanogenerator can produce electricity from one’s heartbeat or from the in and out movement of the lungs during breathing. This means that the Nanogenerator can be used in making pace makers for people with heart problems. This would go a long way because by using this technology, issues of replacing the battery of battery run pacemakers and also maintenance issues of the pacemakers that would be required. It would also help in avoiding the many risky and costly operations that patients have to go through.
Nanotechnology, shortened to "nanotech", is the study of the control of matter on an atomic and molecular scale. Nano science and nanotechnology are recent, revolutionary development in Science and Engineering that are evolving at a very fast pace.[1,2] It is driven by the desire to fabricate materials with novel and improved properties that is likely to impact virtually all areas of the physical and chemical sciences, biological sciences and health sciences. The word ‘nano’ derives from the Greek word ‘nanos’, which means dwarf or extremely small and mathematically, a nanometer is a billionth of a meter or 10-9 m. Particles whose sizes fall in the size range of 1-100 nm is called a nano particles, whether it is dispersed in gaseous, liquid or solid medium. Generally nanotechnology deals with structures of the size 100 nanometers or smaller, and involves developing materials or devices within that size. Nanotechnology is very diverse, ranging from extensions of conventional device physics, to completely new approaches based upon molecular self-assembly, to developing new materials wi...
What is the goal of technology? Most answers include some form of ways of increasing speed, or decreasing size all for the ultimate goal of convenience. Ok, so what is convenience? Convenience is the skill level at which something can be achieved, in other words, how desires can be met. So the true goal of technology is to assist in meeting desires. The quicker and smaller technology is, the easier it is to obtain those desires. Nanotechnology is the newest wave of technology that will potentially make a huge breakthrough in technology’s goal. Though not a science secure as of yet in our world, it is waiting for the time to make its momentous break though into the modern world, bringing with it a global effect on the human way of life.
“Nanotechnology is science, engineering, and technology conducted at a nanoscale which is about 1 to 100 nanometers,” according to the National Nanotechnology Initiative. A nanometer is a billionth of a meter, there are 25,400,000 nanometers in an inch and a sheet of newspaper is about 100,000 nanometers thick. Putting that into perspective, if a marble were a nanometer, a meter would be the size of the Earth. Nanotechnology can be used throughout all fields of science, including chemistry, biology, physics, materials science and engineering to study and apply extremely small things. Physicist Richard Feynman introduced the concepts of nanoscience and nanotechnology with his talk titled “There’s Plenty of Room at the
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"
Relational database management systems are composed of objects or relations. They are managed by operations and governed by data integrity constraints.
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
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.
Nanotechnology is science, technology and engineering that is conducted at the nanoscale. The nanoscale is about 1 to 100 nanometres.
The database application design can be improved in a number of ways as described below:
Nano refers to 10-9 power or one billionth. Nanoscience is ths study of atoms, molecules and objects whose size is on the nanometer scale (1-100nm)
The Database Management System (DBMS) is software that enables the users to define, create, maintain and control the access to the database. It is a software that interact with the user’s applications programs and it database. Meanwhile, information retrieval system is a system that involved the activity that the systems obtain the information. The obtaining information action need the information from it resources.
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.
