Label each file name according to the section of the assignment it is written for. Additionally, you may create and / or assume all necessary assumptions needed for the completion of this assignment.

Large companies have been using the power of business analytics for quite a while now. Your company desires to get in on the action; company executives believe that using advanced data analysis will enable the company to make smarter decisions and improve business performance. Business analytics gives companies the ability to look at past realizations and performance as well as set up new expectations and performance goals. Analytics-as-a-Service is a new delivery model that uses cloud technology to provide business insights without enormous infrastructure enhancements. The executive team has heard great things about analytics and cloud technology but is apprehensive because they are unfamiliar with the look and feel of the technology. The executive team is interested in your recommendations and eagerly awaiting your forward-thinking viewpoint.

Section 1: Design Document

  1. Write a four to six (4-6) page design document in which you:
  • Support the need for the use of analytics and cloud technology within this company.
  • Create a workflow diagram to illustrate how analytics and cloud technology could align with the company’s business processes. Note: The graphically depicted solution is not included in the required page length but must be included in the design document appendix.
  • Create three to five (3-5) screen layouts that illustrate the interface that organizational users will utilize. Note: The graphically depicted solution is not included in the required page length but must be included in the design document appendix.
  • Give one (1) recommendation for solution providers that could help your company secure a firm advantage by using analytics and cloud technology.
Your assignment must follow these formatting requirements:
  • Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
  • Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.
  • Include charts or diagrams created in MS Visio or Dia as an appendix of the design document. All references to these diagrams must be included in the body of the design document.

Running head: PROJECT DELIVERABLE 3: DATABASE AND DATA WAREHOUSING DESIGN Project Deliverable 3: Database and Data Warehousing Design Bennie Carter CIS 499: Information Systems Capstone Darcel Ford Monday, February 4, 2019 1 PROJECT DELIVERABLE 3: DATABASE AND DATA WAREHOUSING DESIGN 2 Why a Data Warehouse is needed in the Company In the contemporary business environment, it is reported that a paltry 0.6% of data available to each organization is being utilized yet in the same breadth; companies in the US on averagely lose businesses worth billions of dollars because of using bad data to obtain analyzed information. Such gives an impression that the company data are not properly stored and analyzed to accurately guide decision making processes in the company. The kind of investment companies put towards data gathering, storage, security and processes involved in manipulating the same data to derive logical meaning from it over and over is enough testimony how data can remain to be core in influencing the direction a business takes (Manikandan, Lavanya, & Gokila, 2018). In today’s business space, the culture of doing business heavily depends on data especially while determining important business forecasts in relation to the situations in existence. Unfortunately, the data available can only serve to perfect or spoil completely. Data only remain powerful if it can be used while in the right state, which is a product of data organization and analysis (Black, Keene, Lamb, & Oglesby, 2018). Archaic storage of data and running ineffective data analytics only serves better in compounding company data-related problems. The arrival of data warehouse technology, however, caused a paradigm shift as far as storing data, analyzing and reporting are concerned together with the speed with which it is accessed. Data warehouse basically is the place from which historical and current data are stored. In an organizational setup, the scope of the data warehouse spans across all departments hence creating one giant data repository to ease analysis which is normally key to market research, PROJECT DELIVERABLE 3: DATABASE AND DATA WAREHOUSING DESIGN 3 generating analytical reports and more critical decision support mechanism. A clear contrast between traditional databases and the data warehouse in terms of the scope of data each handles. While the former works best with a snapshot of current data, the latter houses a range of data dating several years back up to the currently available data hence granting in-depth analysis and reporting. Best Practices the Company must adhere to A company before embarking on a process to put in place a data warehouse should at basic levels align itself to some guiding principles dubbed as best practices. The principles are normally constructed cleverly to ensure the company benefits maximally from the data warehouse project while at the same time ensuring areas of conflicts are minimized. Some of these practices include aligning the project to business objectives and corporate strategy of the company, building an incremental data warehouse, building in adaptability and have the project be under the management of IT specialists and business professionals. A schema that Supports Company's Business and Processes Basic requirements of a schema comprise fields, tables, views, relationships, and indexes. Tables UserData- Main purpose of the table is to contain information pertaining to each user that accesses the system. The fields contained include username followed with a password, and lastname, employee_id, title, and level. Another table is Usermanagement- used to monitor data contribution that a given user is allocated in the system. The fields contained in this table include UserID, Original_Level, DateCreated, and the New_level. The next table in the schema is Levelwhich defines levels a user can get in the system. Fields in the table include Level_number and PROJECT DELIVERABLE 3: DATABASE AND DATA WAREHOUSING DESIGN 4 level_description. Another table worth noting is knowledge which comprises the information the user feeds into the system for use by other system users. Fields in this table include knowledge_ID, Created_by, Approved_by, Description, Category_name, and Approved_for. Knowledge statistics table monitors frequency within which a piece of information (information piece) is accessed. Fields include KsId, UserID, Date_Accessed. For the table Media_Details, information such as data related to maps, the knowledge to the files and any other media related details. The fields include KID, ID, MDID, and media_description. Finally, categories become the last table to be discussed. The table comprises set information regarding categories from which each media and knowledge fall into. The fields found in the table include Category_Name, Category_Id, Category_Description, DateCreated, and CreatedBy. Relationships The relationships at the Userdata table are one to many symbolized by 1-* for the tables; knowledge table, UserManagement table, Media_Statistics table, knowledge_statistics table and lastly relationship with the media table. On the contrary, the UserData table relationship with the Level table is many to one symbolized as (*-1). In the knowledge table, there is one to many (1*) relationship to the Knowledge_Statistics table. However, the relationship with the UserData table is many to one (*-1). The Kowledge_Statistic and UserManagement table relationship is many to one (*-1) and many to many (*-*) with the media_statistics table. The rest of the relationships between the tables will be visibly shown on the E-R diagram. Views Views are query defined objects. Views sometimes are referred to as virtual tables since they don’t store data. In this schema, views can play a key role in joining as many related tables PROJECT DELIVERABLE 3: DATABASE AND DATA WAREHOUSING DESIGN 5 as possible. For example, the tables UserData, Knowledge, UserManagement, Media_Statistics, Media, and Level can be joined. The use of views helps achieve quite a number of advantages such as enforcing business rules, maintaining consistency, beef up security through table access restrictions, introduces simplicity to the design work by creating room to join related tables, and finally they help a great deal in saving on space. Indexes The relevance of index in a database is to speed up data retrievals from a mesh of tables. A company database contains myriads of tables with multiple rows and columns. An index initiates the quick search operation and retrieval through selected data form columns. For example, from the above schema tables, an index syntax to perform specific data retrieval in the table UserData would be SELECT sir_name FROM User_Data WHERE sir_name LIKE Chambers. Explanation and Support The database schema structure above contains tables with fields, the relationship between the tables, views, and indexes. Key elements such as constraints, relationships, and data items are insightfully explained through the use of advanced data model concepts. By understanding the schema well, one is able to travel through the journey of database design steps (the logical design and physical design) without much difficulty. Additionally, one is equally able to appreciate the simplicity of the whole database design process by just borrowing a little from the logical flow of the schema with its high-level abstraction. PROJECT DELIVERABLE 3: DATABASE AND DATA WAREHOUSING DESIGN 6 Entity Relational Diagram The main essence of the entity-relationship diagram (ERD) is to provide a graphical illustration of the database entities and also to define the relationship between each and every entities (Heayyoung, Omori, & Ohnishi, 2018). The ERD becomes very crucial when designing a standard database because of its high-level logical data model. It is a simple paper representation of the actual complex database which in reality may prove tough to understand as a result of the high level of abstractions. From the company ERD, one can easily deduce how the many company database entities are associated with each other. PROJECT DELIVERABLE 3: DATABASE AND DATA WAREHOUSING DESIGN 7 Data Flow Diagram (DFD) USER /EMPLOYEE DATA SOURCE USER CONTRIBUTION (Knowledge addition) ID DATA STORE (User data) Data Categorization ID (User data) DATA STORE (User data) (User data) USER /EMPLOYEE INFORMATION ACCESS FREQUENCY USER /EMPLOYEE DATA CONTRIBUTION MONITOR ACCESS LEVEL (Extent a user can go) DATA SOURCE DATA SOURCE The Data Flow Diagrams further unravels design ambiguities by clearly showing activity flow from the input point, all accompanying transformations until the output is achieved. DFDs comprises 4 main components: entities, data stores, processes, and data flow. Symbols used in DFDs to represent the interaction between the components varies depending on the model being handled. However, the syntax for the longest time has remained the same. DFDs have gained a PROJECT DELIVERABLE 3: DATABASE AND DATA WAREHOUSING DESIGN 8 lot of attraction from object-oriented analysts due to their strong emphasis on module-based design.
