Database Administrator The career I have chosen to research is database administrator. According to a report released by the U.S Bureau of Labor Statistics, “Employment of database (DBAs) is projected to grow 11 percent from the 2014 to 2024, faster than the average for all occupations. Growth in this occupation will be driven by the increased data needs of companies in all sectors of the economy”(1). The 11 percent might not seem like a lot compared to the specific field but if you really…

Definition of Data: The term data is known as representation of objects, events which are stored and recorded in the computer and the data exists in a variety of forms such as values, variables and numbers and so on etc. EX: The database in a hospital contains data such as name of the patient, address, disease and contact number. Definition of Database: The term database is determined as data collection in an organized manner and every data present is related to each other in some other way.…

The benefit of using a relational database is that it can help the efficiency of data storage by avoiding data duplication. It is very easy to change data and the format of it which can be added or removed easily. The data can only be stored once so no more than one record change is needed. Relational databases are used to work together by primary key and foreign key as this creates a link between more than one table. By this it can use the attributes and entities within the database which makes…

We pass from an industrial age to an information age around 1940 in US, but as far as around 1858 for Britain. The Information age, however has growth at a fast pace living the old school behind where in person and/or days and even months for delivery of information has become a thing of the past. Today messages and information are at the touch of the fingers and has expand to most part of the world. But what makes this age to important, how database management system has help to stay current…

Another operations management technique widely used in the business world in linear programming. What is linear programming? Linear programming is a commonly used mathematical technique designed to help operations managers plan and make the decisions necessary to allocate resources (Quantitative Module B: Linear Programming). In addition, Linear Programming (“LP”) is one of the few operations management techniques that will guarantee an optimal answer, providing that all of the assumptions are…

from 1 to 0. Explanation on how this is done is dealt in the later chapters. A backup reset can be generated when VDD or VBAT power on, if both supplies had been previously turned off. It can also be done in a software way when RCC_BDCR bit is triggered. BDCR means backup domain control register. For this task there is also a function written namely, RCC_BackupResetCmd(). Now I would explain more about accessing the backup domain. After a reset these registers are protected against write access…

Would war have such a negative connotation if there was no aftermath? No grief, no mourning, no rebuilding, no tensions, just an end. In short, that would be extravagant. Humans could fight, make a stand, change, and that would be it. Blissful. The reality presses down unrelentingly,as this will never happen. War is gruesome and malevolent affair with no victors. When the recovery period after war is considered, the price and the ensuing struggle, there is no escaping what has already been done.…

The gradual transformation in data quantity has resulted in emergence of the Big data and immense datasets that need to be stored. Traditional relational databases are facing many difficulties meeting the requirements of the volume and heterogeneity structure of big data. NoSQL databases are designed with a novel data management system that can handle and process huge volumes of data. NOSQL systems provide horizontal scalability by supporting horizontal data partitioning across heterogeneous…

Data, information, knowledge and wisdom are referred to as the DIKW hierarchy model cited in Figure 1. This visual metaphor illustrates large amounts of data at the bottom of the pyramid which are reduced to smaller amounts of information consequently creating more condensed knowledge and even smaller wisdom. For Ackoff (1989) data is a symbol and does not have meaning on its own. Information emerges from data that has been processed and hence data has now been given meaning. Knowledge is built…
