Data warehouses merge the data fetched from different sources and give it structure and meaning for the analysis. A. : These are the purpose-specific sub-databases of the data warehouse containing only some parts of the entire big data. Data from the traditional database using the Online Transaction Processing (OLTP) is used. Over time, more data is added to the warehouse as the multiple data sources are updated. As opposed to this, if you fetch raw data, directly from the data source, you might face issues with the uneven formatting of data, data being unstructured and not sorted. Business Intelligence tools require such data from the data warehouses. Whereas, if you need data for more subjective and holistic queries like factors affecting order processing time, the contribution of each product line in the gross profits etc., data warehouses are used. Data warehousing is the electronic storage of a large amount of information by a business or organization. However, in order to query the data for reporting, forecasting, business intelligence tools were born. Application software then sorts the data based on the user's results. In data warehousing, data is de-normalized i.e. In a 3NF state, every field of the table in a database is functionally dependent on only the primary key and does not contain any indirect associations. (a) is true, (b) is false Both (a) and (b) are true (a) is false, (b) is true Both (a) and (b) are false. But blockchain is easier to understand than it sounds.

A) normalized. warehousing and data mining, and it highlights the techniques and the limitations of analyzing and interpreting enormous data. This set of MCQ questions on data warehouse includes collections of multiple choice questions on fundamental of data warehouse techniques. Actually, in the past, businesses have really struggled with the concept. In each data mart, only that data which is useful for a particular use is available like there will be different data marts for analysis related to marketing, finance, administration etc. The data is transported through the Online Analytical Processing (OLAP). These BI tools query data from OLAP cubes and use it for analysis. 31. Business Intelligence and data warehousing is used for . Data warehousing and Business Intelligence often go hand in hand, because the data made available in the data warehouses are central to the Business Intelligence tools’ use. What is Data Warehousing?

IBM data Stage is a business intelligence tool for integrating trusted data across various enterprise systems. A holistic approach to deal with and manage immense amounts of data that we use at enterprise levels. The process by which we fetch the data into data warehouses from the source is ETL (Extract, Transform, Load). Data warehouse contains ..... data that is never found in the operational environment. And also, helps in customer interaction which includes, sales analysis, sales forecasting, segmentation, campaign planning, customer profitability etc. Step 3: If you wish to use data from the data warehouse for specific purposes like marketing analysis, financial analysis etc., subsets of the data warehouse are created known as data marts and data cubes.

Step 1: Extracting raw data from data sources like traditional data, workbooks, excel files etc. Forecasting. Data warehouses merge the data fetched from different sources and give it structure and meaning for the analysis. Also, we discuss how BI tools use it for analytical purposes. D) All of the above. Also, decentralized data and data retrieval from the source was a slow process. When a user needs data related as a result to the queries like when did an order ship? ... business intelligence (BI) or data … At the front-end, exists BI tools such as query tools, reporting, analysis, and data mining.

Consider the following two statements: (a) Business intelligence and Data warehousing is used for forecasting and Data mining. Data warehousing and OLAP has proved to be a much-needed jump from the old decision-making apps which used OLTP. Instead, a copy of that we take data into an integration layer staging area where manipulate and transform it in specific ways.

After the data has been compiled, it goes through data cleaning, the process of combing through the data for errors and correcting or excluding any errors found. Which one of the following options is correct? Data lakes and technologies like Hadoop follow Extract-Load-Transform which comparatively more flexible process than ETL.
