Oracle Employ And Manipulate Users And Roles - 1253 Words

Oracle DBAs employ and manipulate users and roles, as well as various other objects on a daily basis. They do not belong to a schema similar to other objects, including profiles and tablespaces. Users and roles access schema objects like tables, views, synonyms, and indexes. Even novice DBAs possess a reasonable awareness of working with tables including querying, updating, reading, and deleting data from them. Because tables can easily expand in row numbers, performance will inevitably suffer. An adept DBA should retain a fundamental expertise of indexes to alleviate these performance issues. Much like the index of a book, a database index speeds up table searches by adopting pointers to rows of data in contrast to performing full table scans to locate a minute amount of data. An index is a data structure (most commonly a B- tree) that stores the values for a specific column in a table. The B-tree index is the prevailing index and takes advantage of an efficient algorithm for searching columns of high cardinality. This type of search is performed in logarithmic time which exponentially decreases the time to execute a search. Fig 2 illustrates a B-tree index and how it provides more granular levels of information at each level. An index is constructed on the last name column of a table. Oracle uses ‘Miller’ as the root node and divides any last names that are alphabetically less than Miller on the left child node and any last names greater on the right side.

(qtd in ScienceDaily, screen 1) Studies performed were mainly based on American diet, therefore similar studies may be conducted to evaluate whether these findings apply for other racial and ethnic populations. These information would really be useful for individuals who have diabetes or are at risk of developing diabetes; as well as the general population for the promotion of health and prevention of disease. However, to a reader without extensive nutritional background, results of this study may be misleading. The report may mislead by giving the reader the notion that drinking milk alone will be prevention enough against diabetes. Other preventive measures for diabetes should have been included in the report to avoid misinterpretation.

Question: Discuss about the Strategic Information System. Answer: Introduction Strategic Information systems are developed for business initiative. They provide competitive advantage to an organization. An organization is made of various components. It is very important that there should be integration, where all departments are linked together. Certainn departments in an organization are not that important and there are certain that are important. One such department, that is important is Accounts department. Accounts department keeps all the records of transactions and all other accounting related operations. Changes in the technology pattern has also affected accounts department. Automation and integration of packages offered requires services and accounting operations by numerous suppliers in the market. Australia has also witnessed this change, presence of providers who provide services and accounting operations to the customers. Organizational Background Online retailing is growing day by day and many organizations in Australia and in other countries who are in this field. They have captured a huge market share and have been satisfying the customers by providing a good quality of services. Woolworths Limited can be taken for example, has retail stores which offers a wide range of products like groceries and many more. Organization structure of Woolworths consists of many levels where the resources are allocated. These are top management, leadership level, operational employees and others. Combination of these resources from different levels is very important for Woolworths to attain its goals (Woolworths 2017). Various aspects of modern organizational structure It is observed that there are several levels in which the resources of Woolworths has been placed. Woolworths can achieve is goals only when all these levels they collaborate. But such integration is currently absent from Woolworths and in order to get an competitive advantage over the other major players in the market Woolworths need have an integration of sysetms and sub-systems within the organization. System Acquisition Method Many system acquisition methods can be applied in Woolworths case. The organization can use custom software and they can also apply the necessary functionalities with the help of commercial software. The best method will be the use and application of Enterprise Resource Planning (ERP) (Yang and Tamir, 2015). ERP will help organization to cope the various issues related to the organizational structure. The process of sales in Woolworths can be divided in four stages The objectives of business are the inputs of the sales process which results in customer satisfaction as an output. There are other sub activities as well that falls in between.

Consequently problems related to monitoring and controlling occur. Tracking manually and managing these activities is not easy due to operational complexity (Ryan 2016). Therefore, automation of system should be used with tactics for better controlling and monitoring in the process of sales. Due to the various activities, frauds occur and malpractices have been observed in information handling and exchange. It is very important for the organizations to avoid situations of fraud. These kind of fraudulent puts the reputation of the organization at risk and also the put the organization at legal battles. Organizations must and they at most times monitor the fraudulent activities that might occur.
