1. Dedicated file architecture- Privately designed files are allocated to each and every application. With the application the data structure is deeply embedded and the control of data files is with application. 2. Closed database architecture- Database management system has lot of advantages over file systems like security, view, recovery etc. but the separate databases are still designed for almost all applications. This is real with dedicated file architecture, which has high degree of data redundancy and poor administration. Spaghetti looking interfaces move data between the closed databases which are known data scrubbers. They usually do not add any value and compensate for inefficient data administration. 3. Subject data base architecture- Based on its own internal attributes the data is analyzed, …show more content…
a. Coming together of inverses- A linear logic act progress into an inverse of itself i.e. is X becomes not X. Meaning of this is nothing but an advantage which is unrevised becomes a drawback. This kind of contradiction occurs due to unavoidable reversal due to contentment of the champion and starvation of losers. b. Reversal of inverses – for the accomplishment of the goals, doing the inverses of the linear logic would help. Basically to get X set the actions of not X. This happens due to environment of conflicts of inverse simple linear logic. Growth of the market Even though the concept of data warehousing is not that old, but the evolution of the technology is quite fast. With the arrival of the cost effective MPPs using COTS i.e. commercial off the shelf disc drives with the RAID III technology, vector systems collapsed in the value when it is compared to parallel processing manufacture, installation and startups. Data warehousing is the most talked about and important topic in the information
The company can make use of SAP BW/4HANA warehouse in order to perform any analytical operations on real time data. Using this data warehouse the company can generate reports which will be helpful: • For the business managers to know more about their product manufacturing and distribution costs. These reports will provide them with necessary information so that they can build new ways to reduce overall
DataClear had also recorded very impressive sales growth in its first two years and, given the projections, were looking at 300 percent average revenue growth thru '02. The case analysis available shows that DataClear has a $600 million annual domestic market for its current product and $1.2 billion when you add in the global market in telecommunications and financial services. With product expansion, there was a potential annual $2.7 billion market ($1.5billion domestic/$1.26 billion abroad) to target in the telecommunications, financial services, chemical, petrochemical, and pharmaceutical industries combined.
... different layers such as ETL stage, SIF, BDW and how data is processed to generate reports according to the requirement. The processing of information from raw data to different processing stages culminating in coherent information is fascinating.
The database application design can be improved in a number of ways as described below:
A data warehouse comprised of disparate data sources enables the “single version of truth” through shared data repositories and standards and also provides access to the data that will expand frequency and depth of data analysis. Due to these reasons, data warehouse is the foundation for business intelligence.
The last decade can be marked as a period of significant changes in the business world. Being accustomed to utilize computers as a powerful tool with its office applications such as Microsoft Word and Excel. In the 1990s office workers first faced the opportunity to share information using the Internet (McNurlin, 2009). However, the situation became even more different with the transition to the third millennium. With a further development of information technologies, the majority of big enterprises had to reconstitute their business processes and to make the transition to the Internet economy. Enterprise resource planning (ERP), supply-chain management (SCM), customer relationship management (CRM) software and the variety of other information systems became essential components of the new economy. It can be expected, that all these complex solutions were designed to bring great benefits for different sides of the corporate activity, in particular, decisions made by top-managers are expected to become nearer to the ideal, customer service is to be improved and collaboration more prolific. Nevertheless, to ensure the desired results it should be taken into account that the key concept of these reorganizations is an information or a data, dealing with which can be a serious issue, and wide utilizing of the data warehouses in contemporary organizations confirms this fact.
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, 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.
Within the analysis phase a set of goals are needed within the domain. From this there are three perspectives which are taken; the object model the Ronald LeRoi Burback (1998) states “dynamic model, and a functional model. The object model represents the artifacts of the system. The dynamic model represents the interaction between these artifacts represented as events, states, and transitions. The functional model represents the methods of the system from the perspective of data flow.” After the analysis phase the system design phase takes place. Here the system is sub-categorized and appointed tasks and persistent data storage is established, also within this phase the architecture is formed. Lastly the object design phase starts and is where the implementation plan is established and algorithms and object classes are also
As we all know that Exascale computers runs million processors which generates data at a rate of terabytes per second. It is impossible to store data generated at such a rate. Methods like dynamic reduction of data by summarization, subset selection, and more sophisticated dynamic pattern identification methods will be necessary to reduce the volume of data. And also the reduced volume needs to be stored at the same rate which it is generated in order to proceed without interruption. This requirement will present new challenges for the movement of data from one super computer to the local and remote storage systems. Data distribution have to be integrated into the data generation phase. This issue of large scale data movement will become more acute as very large datasets and subsets are shared by large scientific communities, this situation requires a large amount of data to be replicated or moved from production to the analysis machines which are sometimes in wide area. While network technology is greatly improved with the introduction of optical connectivity the transmission of large volumes of data will encounter transient failure and automatic recovery tools will be necessary. Another fundamental requirement is the automatic allocation, use and release of storage space. Replicated data cannot be left
The dynamics of our society bring many challenges and opportunities to the business world. Within the last decade, hundreds of jobs have emerged particularly in the technology sector to help keep up with the ever-changing world and to compete on a larger and better scale than the competition. Two key job markets and the basis of this research paper are business intelligence or BI and data mining or DM. These two fields play a very important role in small to large companies and are becoming higher desired sectors within the back offices of the workplace. This paper will explore what the meaning of BI and DM really is, how they are used and what we can expect as workers and learners of the technology and business fields for the future.
For the past couple of decades the majority of businesses have wanted to construct a data-driven organization or company. Furthermore, companies around the world are considering harnessing data as a basis of competitive advantage over other companies. As a result, business intelligence and data science use are popular in many organizations today. The increase in adoption of these data systems is in response to the heavy rise in communications abilities the world over. Which, in turn ,has increased the need for data products. Indeed, the Data Scientist profession is emerging to be one of the better-paying professions due to the urgent need of their labor. This paper is going to discuss what business intelligence is all about and explain data science that is usually confused to be similar to business intelligence. I will tackle a brief overview of data scientists and their role in organizations.
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.
