'List of the infobases in which selective information about you exists •Flat- cross-file entropy bases. The planar file informationbases atomic number 18 expendd to store miniature amounts of information that is required to be edited by the hand. They be do up of files strings that coincide one or more files and they argon impelling in storing simple info lists but they bring forth complex if the selective information structures atomic number 18 replicated. Flat file infobases require a simple arise to the methods of storing information, thereof if complex data types ar stored, the file bend unread equal to(p) for the single(a) using the data bases.\r\n m whatever an(prenominal) an(prenominal) companies use the flat file data bases in storing their data since they argon easily assessed and edited (Matthias, 2003). • horde databases The server databases uses the net and it is easily accessed by the clients at each time, for instance, 24 hours , one week. The clients be fit to access the websites in order to imagine the data. horde databases are applic able to many companies that require to provoke performances and communications on data issues anywhere in the world.\r\nServer databases chip in a special trait that aloneows the clients to deliver particularised data requests from the database and then it is the indebtedness of the database to perform the function (Matthias, 2003). •Relational databases An example of a rational database embroils the SQL server databases. These types of databases uses a logical readying in the processes that they store data. For instance presentation of tables in data storing where by each field is exposit by a true character.\r\nThe realtions in the databases are exposit when the characters are linked with one an new(prenominal). many companies uses the relational data,bases since they are effective when they are intentional propely and therfre resulting to clear da ta analysis without any extra (Bing, 2011). ii): Make a list of the databases in which data about you exists. How is the data in each database captured, updated and how very much? What data privacy concerns do you have? rationalise briefly. info sources are delimit by their portability mechanisms and the self-sustaining approaches that enhances the connection of the databases.\r\nThere are variant types of data sources and they are introduced to define a certain database. An application stinker be use to define unalike types of database by changing the components of the data source. There are trey different types of data sources, managed data sources,native data source and operational data sources (Pang,2001). •Managed data sources Managed data sources define the approaches employ in error discussion mechanisms, connections pooling as well as global execution anxiety. Since they are applicable on global proceeding they are usu wholey updated on daily basis.\r\nA managed data source in a data store declare oneselfs all the implementation mechanisms and interfaces that are issued in the data source. The retentiveness storage warehouse can be able to use the managed data source in the elaboration of global transactions (Pang,2001). • primaeval data sources Native data sources are significant in the warehouse interface and are provided by the vendor’s sich as oracle. The native data source are different from the managed data source since the connections cannot be retrieved in global transaction.\r\nThey are updated with several approaches depending on the information to be retrieved. Operational data sources All operational data sources applicable in a warehouse are apply in the management of data in different sectors. The data sources are retrieved by the application of connections that enhance the operational process of data retrieving and enhancement effective. In a datawarehouse basis, information of data is retrieved from more than one ideal source thence the application of the operational data source defines different strategies of connection to effectively define a certain data. ii): Using your caller-out of choice example from above, apologise the type of ending wear that thecompany can returns from implementation of a data warehouse. Within this context, what would bethe single- surveyd function of data mining? Decision jump constitutions are important computerized information that enhances the strategies that are utilize in determination making (Power, 2002). The decision makers are able to use the networking communication technology, data information and other models to enhance the approach of decision making.\r\nDecision support systems are significant in the company since they provide information on graphical approaches and include expertness application on artificial intelligence (Power, 2002). BLM family is entitled to use the communication driven decision support system that has a responsibility in targeting internal patterns. The importance of the communication driven decision support system is to enhance individual collaboration. The technology that is applied in this type of decision support system includes the client services for instance, instant messaging. fictitious character of data mining •analyzing\r\nData mining softwares are important in analyzing data from different perspectives (Bing, 2011). It analyses, categories,summaries and indicates the descent that occurs in a given data. Data mining procedures are effective since they analyses the total components that the user wants prefers effectively. • intent of valuable information Data mining is defined as the processes that are used by data software to analyses, summaries useful limit. Data mining provides all the knowledge that is required to uncover certain figures connect with information retrieval for several applications.\r\nIn such(prenominal) cases, cross tabulat ion information, decision trees applications can assist in the retrieving of certain valuable information. QUESTION 2: Enterprise Content Management (electronic countermeasures) helps companies to capture, organize and poll particularly unstructured content to deliver get out business. ECM technologies cover a broad delineate of capabilities. With the help of examples name and briefly inform three of such capabilities. •Document management capability either department in an giving medication is conversant with put down management capabilities.\r\nThe role of ECM In to the highest degree of the institution is to assist the organization on the approaches associated with enter management through the introduction of policies that requires documentation cycle. ECM applies alter methods repositories that enhance the mechanisms of discovering the information effectively and thence the vex policies enable tracking of information in the organization through the applicatio n of bar codes and labels(Handy, 2009).\r\nThe centralized mechanisms have moderated that storage and protection of informations against any self-appointed use, hence they offer security on information. file management capabilities Record management capabilities has been known as a secondary task, strategies that are associated with this capability include, the requirements on clear records assignments within the departments. Record management capabilities figure that records are well updated in the organization to ensure that the organization maximizes transparency. The record management capabilities provides the managers with an opportunity to set up the records according to the organizations filing plans. • mesh content management capabilities\r\nThe development of web content management capabilities ensures that the organization is able to communicate effectively with employees and customers. Web content management capabilities ensures that the organizations is in a impersonate to manage different sectors for instance multilingual Internet sites and mobile services slice it ensures that these sectors are effectively updated. Summary of the findings IBM is a worldwide known company that applies the enterprise content management with software application. They provide semantic data management software within the organization. Question 3\r\nWrite the lecture compend relating to Week 9 †Topic: Data store and Data Mining data warehouse Companies are entitled with different sorts of information. The traditional methods of data storage include, invoices, sales and distribution were developed by many companies and it was a hard task that required a lot of computing producing biased and inaccurate information. With the juvenile innovations of technology and information systems data management and store has become an easy process (Michael, 2009). The effective use of Data storehouse provides an approach of combining all the information that is required by the company.\r\nData warehousing includes the application of all the companies data storage and the retrieving of any information is made easy. Data warehousing is made effectively through the strategies that are associated with the retrieving of information for instance, the pickax process of a certain area to retrieve the data, keying of individual as the subject matter and any data information is retrieved and the group team of the organization develops extraction programs. Data warehousing is applicable in coordination of information and copying of data within the organization and outside the organization(Michael, 2009).\r\nTrusting data sources. Data warehouse is subjected with different departments with a large number of data sources from the external departments. An organization can lack the concord on the quality retrieval of data into the data warehouse, and sometimes it can be a rugged process to access how the data is refreshed. The data sources used by th e organization are diverse; thence there is the need to determine strategies that can be applied in trusting data sources. Tools The tools include the simple reporting query tools which are used to tell us what has happened. On-line analytical touch on gives a reason of the happenings •executive information system extracts information on the users who want to mess with the data warehouse • data mining processes includes the all the statistical techniques that are advanced with intellectual research properties. Data mining components include, cross z softwares and the IBM . The architecture- centralised or distributed. If the data is termed as centralized then it kernel that only one database is applicable to a specific hardware for the access of all users. QUESTION 4 Features and tools in face book\r\nThe features and tools in facebook have different importances on the representation of the companies, public figures, bands. They are the key tools of the entities and t hey include pages and the indite subscribers. •The pages Pages are used to represent company’s public figures, bands. The pages can be applicable to •Profiles with subscribe Profiles with subscribe consists of the strategies that an individual uses to subscribe to another person. In this case the profile with subscribes are used by multiple individuals and they include, intelligence information feed, find friends\r\nEntity attribute mensurate model(EAV) Entity attribute value model is a data model that is used to define entity where by the arguments and properties are used to explain them. The number that is used to describe each entity is relatively modest. This model is also known as the station matrix model. Structure of an EAV table The data that is equal is defined in a spacious approach that is capable of storing the entire space matrix that is be of occupied values. In the EAV model each parameter and property describes the entire entity and each ro w that is represented.\r\nIn EAV model, it stores a single component. The EAV tables are also described as bulky and skinny in which the long strategies describe a specific number of rows while the skinny description defines the number of the columns (Michael, 2009). Data in EAV table is recorded and retrieved in three columns, entity, the parameters and the values. The entity colum defines the distributor point description and the parameter column defines the attribute characters for instance, name, and ID and the value define the attributes.\r\n'
