In simple terms, a data warehouse (DW) is a pool of data produced to support decision making; it is also a repository of current and historical data of potential interest to managers throughout the organization, A common way of introducing data warehousing is to refer to its fundamental characteristics. In addition to a relational database, a data warehouse environment includes an extraction, transportation, transformation, and loading (ETL) solution, an online analytical processing (OLAP) engine, client analysis tools, and other applications that manage the process of gathering data and delivering it … 3. Answer: • Data sources . Data may also come from an OLTP or ERP system. Describe two major factors that drive the need for data warehousing as well as several advances in the field of information systems that have enabled data warehousing. Internal Data: In each organization, the client keeps their "private" spreadsheets, reports, customer profiles, and sometimes eve… DWs are central repositories of integrated data from one or more disparate sources. ________ (also called in-database analytics) refers to the integration of the algorithmic extent of data analytics into data warehouse.

ETL (Extract, Transform and Load) is a process in data warehousing responsible for pulling data out of the source systems and placing it into a data warehouse. Active data warehousing can be used to support the highest level of decision making sophistication and power. Data Transformation is a two step process: Data Mapping: Assigning elements from source base to destination to capture transformations. Data warehousing is often part of a broader data management strategy and emphasizes the capture of data from different sources for access and analysis by business analysts, data scientists and other end users.. Most data warehouse are built using ______ database management systems to control and manage the data. A data mart is a subject-oriented or department-oriented data warehouse.

Make sure that the data’s correct. There are several basic information system architectures that can be used for data warehousing. This preview shows page 4 - 5 out of 5 pages. Real-time data warehousing, also known as active data warehousing (ADW), is the process of loading and providing data via the data warehouse as they become available. It is a scaled-down version of a data warehouse that focuses on the requests of a specific department, such as marketing or sales. Benefits 4. Load Manager Architecture. There is a plethora of nuances in how each process is physically conducted and electronically controlled. 3.

Briefly describe four major components of the data warehousing process. Data are sourced from multiple independent operational "legacy" systems and possibly from external data providers (such as the U.S. Census). Meaning of Data Warehouse 2. It can be achieved on specific theme. Managing data warehouses includes security and priority management; monitoring updates from the multiple sources; data quality checks; managing and updating meta data; auditing and reporting data warehouse usage and status; purging data; replicating, subsetting and distributing data; backup and recovery and data warehouse storage management. It senses the limited data within the multiple data resources . The data warehouse architecture is based on a relational database management system server that functions as the central repository for informational data. The _____ data warehouse architecture involves integrating disparate systems and analytical resources from multiple sources to meet changing needs or business conditions. Data Warehouse Storage Which of the following online analytical processing (OLAP) technologies does NOT require the precomputation and storage of information? Managing queries and directing them to the appropriate data sources. 62) A common way of introducing data warehousing is to refer to its fundamental characteristics. Idiosyncrasies across industries adds further diversity. Components of a Data-Warehouse 1. In the Michigan State Agencies case, the approach used was a(n) ________ one, instead of developing separate BI/DW platforms for each business area or state agency. - 1811351 In which stage of extraction, transformation, and load (ETL) into a data warehouse are data aggregated? It is an evolving tool space that promises real-time data integration from a variety of sources, such as relational databases, Web services, and multidimensional databases. Because the recession has raised interest in low-cost open source software, it is now set to replace traditional enterprise software. The ________ Model, also known as the EDW approach, emphasizes top-down development, employing established database development methodologies and tools, such as entity-relationship diagrams (ERD), and an adjustment of the spiral development approach. 4. Which data warehouse architecture uses metadata from existing data warehouses to create a hybrid logical data warehouse comprised of data from the other warehouses? The role responsible for successful administration and management of a data warehouse is the ________, who should be familiar with high-performance software, hardware, and networking technologies, and also possesses solid business insight. The primary purpose of metadata should be to provide context to the reported data; that is, it provides enriching information that leads to the creation of knowledge.

Hardware resources are dynamically allocated as use increases, All of the following are true about in-database processing technology EXCEPT, with _____ data flows, managers can view the current state of their businesses and quickly identify problems, In_______ oriented data warehousing, operational databases are turned to handle transactions that update the database. 67) Briefly describe four major components of the data warehousing process. What are they? DBMS Components: Data. Tightly coupling different elements of your data pipeline. The data captured by the information system in the warehouse is then passed on to the higher management in order to take better decisions. A well designed data warehouse means that user requirements do not hace to change as business needs change. Based on the data requirements in the data warehouse, we choose segments of the data from the various operational modes. The four main components of a computer system are input devices, output devices, processing devices and the storage devices used to store data within the computer system. More data, coming in faster and requiring immediate conversion into decisions, means that organizations are confronting the need for real-time data warehousing (RDW). Data warehouse thus helps in getting business trends and patterns which can later be presented in the form of reports which provide insight for how to go ahead in the process of business growth. Backup and archive the data. These are the hardware components of a computer system; software is a set of digital instructions for the computer stored in the memory. Looking at sales data over several years can help improve product development or tailor seasonal offerings.

Metadata describe the structure of and some meaning about data, thereby contributing to their effective or ineffective use. As database helps in storing and processing data, a data warehouse helps in analyzing it. When querying a dimensional database, a user went from summarized data to its underlying details. Data are organized by detailed subject, such as sales, products, or customers, containing only information relevant for decision support. How does the use of cloud computing affect the scalability of a data warehouse? Data warehousing can define as a particular area of comfort wherein subject-oriented, non-volatile collection of data happens to support the management’s process. A data warehouse is a repository for data generated and collected by an enterprise's various operational systems. Source data coming into the data warehouses may be grouped into four broad categories: Production Data:This type of data comes from the different operating systems of the enterprise.
