Database Development
The objective of this study is to recommend three specific tasks that could be performed to improve the quality of datasets using the Software Development Life Cycle (SDLC) methodology and to recommend the actions that could be performed to optimize record selections and to improve database performance from a quantitative data quality assessment. Finally, this work will suggest three maintenance plans and three activities that could be performed in order to improve data quality. The second part of this study involves the evaluation of which method would be efficient for planning proactive concurrency control methods and lock granularities and assessment of how the selected method can be used to minimize the database security risks that may occur within a multiuser environment. Secondly, this work will analyze how the verify method can be used to plan system effectively and ensure that the number of transactions do not produce record-level locking while the database is in operation.
I. SDLC and Improving Quality of Datasets
High quality data makes the data resources of the organization more optimal for use in that it promotes both effectiveness and efficiency. Improvement of data quality using SDLC is reported to be in three categories including those of: (1) error detection...

Database Modeling and Normalization Entity Relationship Model (ERM) Diagram is a data model used to describe the database in an abstract method. The relational database stores data in table. The entity in the database could point to several entries. For example, employee is an entity in the relationship database, and a diagram used to create the entity in the database is called entity-relationship diagrams or ER diagrams. (Silberschatz, Korth, 2006). Objective of

Design criteria exist at the levels of the technical, system integration aspects of the database to other systems through XML. This integration is critically important to ensure that the applications created can be effectively used over time and not have any scalability issues. There is also the need for designing the databases at the presentation layer to provide for scalability and flexibility of being able to create applications relatively quickly
Oracle supports stored programs such as stored procedures and packages. This enables the developers to centralize application logic in the database. Oracle provides powerful functions and sub-queries in its SQL statements. Developers can distribute systems by database links, materialized views and distributed queries. This feature saves much cost for developing distributed systems and applications. And there's a lot of features integrated with Oracle, compare to other database it is
