Each of the following activities are commonly performed during the implementation of the Database Life Cycle (DBLC). Fill in the blank, before each activity, with the phase number of the DBLS that this activity would normally be performed. DBLC Task Numbers: 1. Database initial study 2. Database design 3. Implementation and loading 4. Testing and evaluation 5. Operation 6. Maintenance and evolution

Explanation:

Database initial study  : The basic data dictionary components are developed as the entities and attributes are defined during this phase. Database design  : The data dictionary contents are used to verify the database design components: entities, attributes, and  their  relationships.  The  designer  also  uses  the  data  dictionary  to  check  the  database    design  for  homonyms and synonyms and verifies that the entities and attributes will support all required query and report requirements. Implementation and loading  : The DBMS's data dictionary helps to resolve any remaining attribute definition inconsistencies. Testing and evaluating  : If problems develop during this phase, the data dictionary contents may be used to help restructure the basic design components to make sure that they support all required operationsOperation  : If the database design still yields operational glitches, the data dictionary may be used as a quality control device to ensure that operational modifications to the database do not conflict with existing components.Maintenance and evolution : As users face inevitable changes in information needs, the database may be modified to support those needs. Perhaps entities, attributes, and relationships must be added, or relationships must be changed. If new database components are fit into the design, their introduction may produce conflict with existing components.

Ithink your answer will be a

Don’t know sorry if i know it later i would put it here
