30) True/False A data warehouse is updated synchronously, say on a daily basis, each time the production database is updated. 31) is not actually a life cycle phase but involves performing changes, corrections, additions, fixes and upgrades to ensure the system continues to meet its business goals. That is, it occurs after the life cycle has been completed.

When creating a data warehouse, what procedures must be followed?

ALO (Anderson - left - overs.) Enterprises is an organization that provides a wide variety of service offerings for clients. Service types available include bookkeeping, computer installation, computer repair, software installation, taxes, advertising, market surveys, etc. Each service engagement may involve multiple types of service and may include multiple employees. Each type of service has a standard hourly billing rate and can not be entered into the database unless at least one of ALQ's employees is capable of performing that type of service. Employees are trained to perform multiple types of services and can work on multiple service engagements. Employees earn a contracted annual salary based on their credentials, regardless of what services they actually end up performing. Clients are required to pay for a given service engagement in full ( with just one check) within two weeks of the completion date. It is possible for a client to pay for more than one service engagement with…

As part of the Database Life Cycle's initial study, the system objectives must correspond to those envisioned by the end users and stakeholders.   Question 49 options:   1) True   2) False

Computer Science The ABC Car Service & Repair Centers are owned by the SILENT car dealer; ABC services and repairs only SILENT cars. Three ABC Car Service & Repair Centers provide service and repair for the entire state. Each of the three centers is independently managed and operated by a shop manager, a receptionist, and at least eight mechanics. Each center maintains a fully stocked parts inventory. Each center also maintains a manual file system in which each car’s maintenance history is kept: repairs made, parts used, costs, service dates, owner, and so on. Files are also kept to track inventory, purchasing, billing, employees’ hours, and payroll. Create an ERD for ABC Car Service & Repair Centers.

Database Design   Testing (ID_testing,date,observerId) Observer(observerId,observer_name) Type(TypeId,typename) Essentialoil (ID_essential,essentialname,typeId,batchcode) Constituent (ID_constituent,cname,min_percentage,Test_percentage,status)   Before an Essential Oil product is marketed, testing is carried out based on the production batch from any essential oil. This is done to maintain the quality and content of the existing constituents in essential oils. Where the Test Percentage Content must reach the Minimum standard Percentage Content for each constituent. If there is one type of constituent that does not fulfill minimum standard, the batch will not be marketed because it does not meet the standard quality. Question 1. Make an ERD (Entitiy Relationship Diagram) based on the results of Normalization 2. Develop the ERD that you create to implementGeneralization / Specialization.

A new sales ordering system needs a relational database that contains a customer table, a product inventory table, and an order table. Use a word-processing, graphics, or spread-sheet program to draw an entity-relationship diagram showing the relationships among these entities. Next, design each of these tables showing the keys and attributes to be included in each table. Include five sample records for each table.

When performing database queries, it is often necessary to join two or more tables together to produce the desired report. This is the result of . 1) The fact that we have created a normalized database with separate tables and non-overlapping columns in order to reduce data redundancy 2) Premature usage of tables prior to completion of the physical design process Absence of a 3rd generation programming language to code procedural 3) interfaces to the data 4) Poor database design

The duties of a database administrator in relation to configuration management are to oversee and manage the configuration of the database system. This includes ensuring that the database is properly configured to meet the needs of the organisation, implementing changes to the configuration as needed, and maintaining documentation of the configuration settings. The database administrator is also responsible for monitoring the performance of the database system and making adjustments to the configuration as necessary to optimise performance. Additionally, the database administrator must ensure that the configuration of the database system is secure and in compliance with relevant regulations and standards.
