RE: Week 3 Discussion

DLBC has many phases that require activities to complete them. These various activities include creating and defining the scope of the application. One needs to define the goals and how they will be achieved. Other activities are selecting a DBMS and creating database requirements documents that include required activities and materials to create a successful database. Also one needs to design the database by creating documents and a visual plan of the database system before its actually created. The designing of the database requires one to create a database application prototype. One needs to create a database by bringing the design plan to its physical functional form and as well creating the database application prototypes. After creating the database and the application, testing should take place to improve any weaknesses and errors before implementing the new system and application. After testing the next activity is the implication phase. One will implicate the new database system and application and carefully load all new data into the system.
These activities may pose some challenges such as poorly defining the scope. If the scope is not thoroughly defined then one may not know the goals or know or the appropriate activities to achieve the goals. This may lead to a poor design and creation of the database and its application. Poor designing of the database and its application is another challenge. Poor designs may result from one not thoroughly thinking about all components or from one not having sufficient knowledge of the specific DBMS. The poor design also may be a result of poorly defined requirements. This can pose a domino effect that ultimately results in the unsuccessful creation of the database and its application. Another calling is the implementation and the transference of new data. Implicating a new database may cause issues if the database is poorly tested or is implemented with unresolved issues and errors. The final challenge I will discuss is the transference of new data. Transferring new data may pose challenges such as one not transferring all the data and transferring new data that may not be correct or up to date.
These issues can be avoided by simply taking their time, having sufficient knowledge of the DBMS, thoroughly testing the database and its application, fixing all errors and weaknesses, and reviewing data before transference and implications.
