The problems, other than redundancy, associated with the nondatabase approach to processing data include difficulties accessing related data, limited security features to protect data from access by unauthorized users, limited ability for multiple users to update the same data at the same time, and size limitations. 3. What is an entity? An attribute? An Entity is a person, place, object, event or idea for which you want to store and process data.
With an information-centric storage system the information can be shared amongst different departments and areas and also helps to prevent duplication, while providing better redundancy and reliability with dynamic systems that can be repaired and upgraded without the downtime on a server-centric storage system. 3. What are the attributes of big data? Research and prepare a presentation on big data analytics. Big data is any data that isn’t able to be handled by commonly accepted methods of data processing, whether it is database management systems, processing and search
(TCO E) Enterprise applications have become easier to install because: (Points : 5) they have been reduced in function vendors have modularized the applications so they can be rolled out a module at a time vendors have changed their design to make the application more adaptable to diverse business processes Users have become more familiar with how to use the applications 6. (TCO F) Agile Methodologies (Points : 4) were developed because traditional methodologies did not work because software development is unlike any other development activity users seldom know what they want when the project starts all of the above 7. (TCO G) A salesperson clicks repeatedly on the online ads of a competitor in order to drive the
Given a situation containing entities, business rules, and data requirements, create the conceptual model of the database using a database modeling tool. 3. Given an existing relational database schema, evaluate and alter the database design for efficiency. 4. Given an existing database structure demonstrating efficiency and integrity, design the physical tables.
It would be too expensive and time consuming, and the IT staff would have to customize the interface leaving the staff more work to do with integrating the new system. Ch.6 1. Are the DFDs in PE Figures 6-1 and 6-2 balanced? Show that they are, or are not. If they are not balanced, how can they be fixed?
12) User access refers to what objects and data in a database a user has permissions to use. 13) Update permission is the permission to make changes to the database. 14) Delete permission is the permission to remove records from database tables. 15) A business rule is a rule that covers how data are acquired, stored or processed. 16) User access refers to what objects and data in a database a user has permissions to use.

A disadvantage of batch processing is the deferral amid gathering the input data and attaining an output. It can correspondingly be exasperating to discover later that a batch run has failed due to data input glitches. Also, issues come up if customers are asking for information regarding a particular request that they placed. Real-time processing will process each transaction and inputs the information right away. This necessitates that all salespeople and additional personnel have to be
The fabrication phases and the assembly and test phase consist of their own procedures. Nowadays manufacturing process becomes more and more technologically diverse and intense. It results in a decrease in a direct labor percentage of total manufacturing cost. Management considered that an inaccuracy of GEI’s standard cost system caused a poor financial performance. The company need find a better cost system which could truly track costs and identify which of products were profitable and which were not.
This, coupled with production, storage and shipping issues, has resulted in inventory shortfalls and a marked decline in GMP’s profits and customer base. In order to improve quality and efficiency of service, an information system solution to allow GMP to capture and analyze point of sale, inventory and logistics data from our stores and facilities in near real time is needed. In order to implement this project, we need to focus on lean manufacturing; cutting inventory storage requirements; reducing the lead time needed to replenish and make product; establishing more efficient throughput on orders; and maintaining
