The significant amount of database performance optimization is attained through the SQL optimization that endeavors to optimize the queries at the application level.
The first step towards database tuning is to identify the reasons behind the issues and determine the current bottlenecks in the database system. This is an intricate task since the factors that influence the overall performance of a database system are quite diversified. The first classification of factors can be categorized under ‘hardware’ that comprises a processor, disk, memory, and network performance. The other factors include indexing, database design, partitioning or locking that are directly associated with the database system. Also, the issues can occur at the application level of the system. Extensive literature is available about these factors, discussion of which would go beyond the scope of this study. This infers that database optimization requires a very explicit set of expertise and includes the fields of database administration, system administration, and application development. Usually, the hardware related database performance issues are easier to identify and fix than other factors. Many database performance issues also occur due to sub-optimal or wrong indexing and inappropriate use of locking mechanisms. Although the role of database design is also very important in database performance, however, the re-designing of a running database system is not at all feasible as it is complex and requires vast resources. The primary focus of this study is SQL optimization as it offers great potential to improve database performance.
This study is aimed towards determining the gain of optimizing SQL in database systems. The paper will discuss the significance of fine tuning SQL queries. ...Download file to see next pagesRead More

...values and lists. However, this type of database can be complicated if the replication of more complex data structures is involved according to The One Stop Website Shop (2012). One other disadvantage with these types of database lies in the fact that they are easy to corrupt. The relational databases have more logical structures compared to their flat-file counterpart in view of the way that information is stored. Relational databases in existence today include Oracle, SQL Server and MySQL. In the relational database, a table is used to represent actual objects, and every field acts as an attribute. As an example, a table that contains...

...dependencies such as deletion and updating. It is also needed for the purpose of making the relational database model more informative to the average user. Logical Database Design This refers to the development of the database while defining the dependencies and relationships that may come up in the database. The data and information, which is gained in the process, is then arranged in a logical manner and transferred into those objects of storage, which are supported by the database. These storage objects in the case of a relational database refers to the tables into which there are rows and columns/ Physical...

...system is predominantly used in accepting commands provided by application programs and executing them on behalf of the user (Ritchie, 2002). This commands are written in database language of the database management system like SQL. Some of the responses include messages, results of queries, and completion of codes. Database management system normally operate as servers in order to support a wide variety of concurrent users. Application programs which run as clients for the set servers are its immediate users. These clients run on behalf of the end users. In transmission of this commands, communication protocol is required and also responses between servers and clients....

...SQL and Security Answers to the assignment SQL Injection is a form of database attack where the attacker attempts to insert amalicious code into non validated input. The attacker tries to get the database to dump its contents. A sample is provided below: Var TrainCity; Traincity – Request from (‘TrainCity’); Var sql = “select * from OrderTable where TrainCity = ‘”+ TrainCity +”’”’ If the user requests the city table, the query will drop all the data in the city table. The technique used here is that the attacker will pose the query to the database about the table TrainCity. When the database responds to the query it will drop the table with the entries. This table will be dropped to the attacker, and he will have access... to the...

... and confidence (Pathak, 2008). Opting for relational databases can position organizations to fully exploit future technological advances. Normalization Normalization is the process of minimizing data redundancies in databases, and is often employed when designing and redesigning databases (Whitehorn & Marklyn, 2001). This includes the creation of tables and the establishment of relationships between those tables. This is based on rules developed to not only protect the data but also to make the database more flexible by reducing redundancy and inconsistent dependency (Whitehorn & Marklyn, 2001). It is an important procedure that if understood and well implemented, can significantly improve one’s understanding of SQL. Importance... , 2001)....

...Affiliation: Portfolio Optimization Asset Allocation A variation of different assets will provide the investor with a variability of return in the investor’s portfolio and reduce the risk. In order to achieve portfolio optimization the investor has to allocate the portfolio in different asset classes. The most beneficial way to allocate the assets is to let a global touch permeate the portfolio. Look at different national markets in order to find independency, hence reduce the risk (Litterman, 2003). In order to attain optimization at a national level it is of great importance to look at different type of sectors and industries, this is supported by Litterman (2003). ). The...

...Databases In designing databases, the initial steps of drawing the entity relationship diagrams play a vital role in ensuring that the database works efficiently. The key components of these diagrams are entities and the relationships that exist among them. It is therefore wise to draw these diagrams before developing the baseball statistics database. Databases To begin with, we must identify the attributes within the baseball statics. Identified attributes are as follows. Players are labeled as pitchers and hitters. The hitter statics include homeruns, batting average, stolen bases, doubles, triples and walks. The pitcher statistics are strikeouts, walks, saves, innings, pitched, earned runs, wins and losses... and include...
