...Recap of the BIW – ETL Process The most important part of any Business Information Warehouse (BIW) or Data Warehousing is a process of extraction, transformation and loading of the data from different source systems that are able to provide data which are relevant to a business organization. This data is mainly from its core applications that are used by the business units to execute the enterprise business processes across them. The ETL is also a Strategy about how data from different known source systems can be extracted, transformed and loaded into the BIW or data-warehouse system which then can be used for designing queries, reports and dashboards to enable the business to make decision at different level of the organization (Top Level, Middle Level and Operational Level). (a) extracting data from outside sources, (b) transforming it to fit business needs, and ultimately (c) loading it into the data warehouse Enterprise Data Warehouse (EDW) is mega data mart where all the data from various source systems get consolidated and let the other data marts within other systems use it by pushing the relevant into these data marts through ETL process. So EDW can be a data provider (like any other source system) to various data marts, decision support system applications, data-mining or exploration warehouse applications ETL Concept: Components: (a) (b) (c) (d) Source Systems Data Source (PSA – Persistent Staging Area) Transformation Loading Source Systems can be one or more...

...As a result, this generated less sales tax revenue. To offset the budget deficit, the California Legislature passed a bill requiring cities to transfer 20% of their gross property tax revenues to the state. The city is looking for ways to save money and one of those areas is technology. It is impossible to eliminate technology such as computers all together because it’s a big part of the city daily operations. One of the potential options is virtualization of city’s physical servers, storage devices, and end user computers would result in significant savings in cost to the city of Seabreeze. Benefits of Virtualization Virtualization is defined as a technology that uses software to run multiple applications and operating systems on one or more physical host servers all at the same time. Within the host server is comprised virtual computers known as VM (Virtual Machines) are running the operating systems and applications similar to a physical PC. VM are setup as virtual servers and virtual desktops. Below is an example how a virtualization server operates. Example of Virtualization Server One of the benefits of virtualization is consolidation of servers since the city has 72 physical servers. The physical servers could be reduced from 72 to 4 host servers due to virtualization. By consolidating the physical servers, it will reduce cost of maintenance, software licenses, and hardware. One example of cost savings, in 2009, Landmark Healthcare had 63 physical...

...city’s use of information technology. Technology investments cannot simply be eliminated, as they are a critical component of the city’s infrastructure on which key city services rely upon. Therefore it is necessary to identify technologies which can produce a greater return on investment (ROI) through reductions in the total cost of ownership (TCO) of the city’s technology assets. One approach that would meet this need that has been identified is the adoption of server, storage and desktop virtualization technology. These technologies not only represent a significant opportunity for the City of Seabreeze to reduce costs, but it will also enable the city to reduce its greenhouse gas emissions, raise IT staff efficiency, and improve disaster recovery capabilities. 1. Virtualization benefits The term “virtualization” refers to technology that enables a single physical device, such as a server with a large pool of resources (CPU, memory, disk, etc.), to be logically segregated into smaller separate “virtual machines”, or “VMs” that are each given their own subset of resources based on their actual utilization requirements. According to IT-Online (2008) a Gartner white paper found that the average server uses less than 10% of its available computing capacity in a 24 hour period. This trend will continue to grow as advances in the speed of server hardware outpaces the resource requirements of the city’s applications. Without virtualization, whenever there is a need for a new...

...oracle databases in a virtual world and out sourcing the cloud storage. Our current data warehouse is at ten terabytes. This is expected to increase by twenty percent a year therefore this must also be taken into account when searching for a provider of cloud storage. This will save on cost of equipment and also space. This savings of cost and space will be used to hire more technical personnel such as an oracle database administrator and a JavaScript programmer. We currently are running windows 7 but will be upgrading to windows 8 because it is better suited to the virtual world than windows 7. In regards to infrastructure and security, right now we have a basic to average network set up with a DMZ for our clients and intranet with a few firewalls. Not much can be done since we are running a SQL database. This will change when we upgrade to oracle. More security on the network and our client’s information will now be able to be applied. We will also create and maintain a backup center located off site. This center will not be cloud based but an actual server room. We will have to address that privacy issues associated with using a JavaScript method instead of log files to maintain the sites. This is because JavaScript relies on the placing of cookies on a visitor’s computer usually without them knowing. By doing this we are allowing an independent company to store and review that data. The IT department will be responsible for this project with a time line of...

...on the use of IT to provide government services elimination of existing infrastructure is not an option. An alternate solution is essential in order to reduce the total cost of ownership (TCO) of the city’s IT equipment by providing newer technology that will have a higher return on investment (ROI). The option identified to fulfill this need is the adoption of virtualized servers, storage devices, and desktop computers. The conversion to virtualized environments will result in substantial cost savings as well as providing enhanced security, greatly improved disaster recovery, a more competent IT staff, and a smaller carbon footprint. 1. Benefits of Virtualization Virtualization is “the process of creating a virtual, rather than physical, version of something” (Virtualization, 2015). In the IT industry this refers to technology that utilizes software to imitate hardware and create virtual computer systems. One example of this is to use a single physical device such as a server and logically divide up its resources (Processor, memory, and storage) to create smaller , separate “virtual machines” (VM), each with their own tailored set of reserved resources . Most servers in use today are not designed to run more than one operating system (OS) or application at a time. These restrictions typically equate to the need for the deployment of multiple servers for even small data...
