Entity-relationship diagram assists in representing abstraction of logically grouped entities and their relationship to define underlying structure of business objects. Physical data model further derives generation of schema from logical schema to create primary key, foreign key, relationship of objects, indexes, views, stored procedures, and other database objects to support applications by storing and processing data for business functions. Physical and logical data independence separates applications from database dependency in running business logic. Preparation of database architecture provides steps of applying data manipulation language in different schema. Client/server architecture for a database application further underpins the concept of independence of data processing and application logic. Finally, database administrator tool provides utilities for database modeling and design, change management, and backup process to facilitate tasks of a DBA.

Although DBA faces the daily challenges in performing technical task, but interaction with developer is critical in running application and seamless flow of information in the system. Database server evaluation, installation, planning, creating and opening, back up, user creation, design, back up, Performance tuning, patches, and roll out to hosts for database are daily tasks in the life of DBA (Oracle, 2012). DBA can face challenges of boredom from stereotype or overwhelming responsibility in resolving chaos arising from environment issues that requires 24/7 working hours. The most challenging tasks for DBA is to deal with developers of inadequate understanding those can create havoc to the system while using locking or caching. But life can be easy with experienced developers who are well-versed in the system.   ...Download file to see next pagesRead More

Efficiency of Data Mining Algorithms in Identifying Outliers/Noise in a Large Biological Data Base

...? Efficiency Of Data Mining Algorithms In Identifying Outliers/Noise In A Large Biological Data Base Efficiency Of Data Mining Algorithms In Identifying Outliers/Noise In A Large Biological Data Base Introduction The protein sequences numbers in bioinformatics are approximated to be over a half a million. This calls for the need of meaningful partitions of the protein sequences so as to be in a position to detect the role they play. Alignment methods were traditionally used in the grouping and comparing protein sequences. In a later stage, local alignment algorithms were introduced to replace the earlier methods and perform more complex functions. The local algorithms were used to find amino acid patterns that are conserved in protein...

Data base analysis

However, enabling the ordering of the netmask provides the most efficient results for client’s orders but this does not enhance the internal clients in resolving the external addresses. Using the NS1 as a forwarder severs enhances successful name resolution for the internal clients. In round robin disabling, this will prohibit any further load balancing and hence will not enable the internal clients in resolving the external host names. In this scenario the user are likely to suffer from many problems which may prevent them from obtaining IP addresses, these may include the expiry of the users IP address, the incorrect DHCP configuration, duplicate IP address on the same network and lack of DHCP server authorization.
