The names may be retrieved according to beginning letters or other important data (such as item purchased). But for a database of full-text magazine articles, the user will need to search according to name, title, publication, and keywords, among other features. The database will not be able to perform adequately without such usability factors. Even if a database is 'fast' in terms of how it returns queries, the queries must be of use to the searcher.
When developing the infrastructure, a data management system is required to operate the databases, store the information, back up the data, and enforce security. If users are entering sensitive information, password protection and encryption is also essential. The hardware and software used must be adequate to support the needs of the system. And the ease of data entry is also vital if data is constantly being entered and edited. The costs of faulty data entry computer protocols can be currently seen in California, where the statewide system for tracking student data known as CalPADS "has been fraught with problems. District staffers complained they often couldn't get online to enter required data" (Lambert 2010). "Some school districts' student information systems are more compatible with the state system than others. Other districts...
This example, drawn from real life, shows the very serious consequences poor data entry method design can have upon a system, when online forms are time consuming and not designed in an intuitive fashion to suit the knowledge base and the existing records of the likely user.

Joint Application Design Describe how joint application design (JAD) might be considered a better information-gathering technique than the traditional method of requirements gathering? What are its shortcomings? The Joint Application Design (JAD) methodology could potentially be considered a better information gathering methodology compared to more traditional information gathering approaches given its highly structured approach to capturing and validating data. The highly methodical nature of the application design technique that concentrates on identifying
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
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
These factors further accelerate the value and TCO of databases over time. Describe the features, tools, and utilities of Structured Query Language (SQL). How can tasks be automated with SQL? SQL has specifically been designed with features, tools and utilities to enable programmers to support nth-tier data architectures in addition to legacy client-server computing scenarios. The development and continual improvement of the features, tools and utilities of SQL for automating tasks
Database marketing, sales force automation and virtual reality are three of the newest trends in technology to impact the way company's market to their customers. All three technologies offer specific advantages and disadvantages for their use. The appropriate use of the technology must be based solidly on the type of product, costs incurred, and the nature of relationship with clients. When used in a judicious way, all three technologies can
