1. You are working as a database architect for your organization. An application programmer that uses your database has a performance problem. The application she is writing has a looping structure that fires off a SQL statement for each looping iteration. In each SQL statement, only the WHERE statement is altered. What would be your recommendation to her?
If the database in question supports batch processing, the looping structure could instead be used to build a batch of SQL statements one by one, which are then executed together once the loop is done. Because the changes in each statement are fairly minimal, implementation of program logic to accomplish this would be relatively simple, and the performance would be considerably better.
2. In class we discussed Logical Units of Work (LUW) and transaction management. How many logical units of work can you have in a stored procedure? Also, discuss transaction management and how LUW(s) relate to triggers.
It is generally inadvisable/not standard practice to use commit statements within a stored procedure, which mea...

In the Quran, the rules following women are quite simplistic. One of the first is that no matter the woman, god will always be above her. Another few rules are, that men can marry up to four while women can only marry one husband; men must also stay away from the women in his family. Followers of the Quran believe that men were made above women, a quote from the Quran supports this by saying, “Men are in charge of women, because God has made the one of them to excel the other…” (9.1). These rules were put into place not to govern women, but to control a man’s actions; though this may seem irrelevant, but its significance is that it shows the women still have some sort of free will, not just absolute control. Next we have the Law of Adamnan,
What is the relationship between management and mission, resources, the system process, and structure? Which of these internal factors are ends, and which are means?
Some faculties and departments are already using Oracle applications in their day-to-day operations. As time goes by, more and more information users will be working with an application based on Oracle database technology. If you get the opportunity to be a member of an application development team, you will become familiar with the workings of Oracle and relational databases. Other users may have to learn about this popular database management system through their own experience. This article is for our readers who, as of yet, have no access to Oracle databases but have a yearning for learning what they're all about.

"Although fully searchable text could, in theory, be retrieved without much metadata in the future, it is hard to imagine how a complex or multimedia digital object that goes into storage of any kind could ever survive, let alone be discovered and used, if it were not accompanied by good metadata" (Abby Smith). Discuss Smith's assertion in the context of the contemporary information environment

In this report I will discuss briefly how transaction management can be used within the database I will also discuss how concurrency and recovery can be used within databases I intend to use the database platforms provided by Microsoft and Oracle.
Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.
The database application design can be improved in a number of ways as described below:

Another function of the DBMS is the concurrency control services. Database Management System must ensure that the database is updated correctly because the database can be used by many multiple users. The DMS enable many user to access the data concurrently. The database managements system will help from ay data loss. It have the features which that can support the updates like batch processing, locking, two-phase locking and the time stamping.
