Security And Performance Of A Customer Relationship Management System

A relational database is a database that consists of a collection of tables with columns showing entities, and rows showing data. This type of database uses a primary key and foreign key. The foreign key in another table will point to the primary key of a table, and this is how tables can relate to each other. This permits for one-to-one, one-to-many, and many-to-many relationship between the data. An advantage of relational databases includes the ease of adding or modifying new tables and entities without needing to change the structure of the database already in place. Relational database have many features, including indexing, setting data type, and setting validation tests, all these help to ensure data integrity.

Which database management system platform should I use? This is a very common question that developers ask themselves when they work on a project that requires storing and querying data. There are 4 well-known platforms that people may consider; they are: Oracle, Microsoft SQL, Teradata and DB2. This essay will compare and contrast the differences and similarities between these fours platforms.

This must be in your own words and not copied and pasted from the original source. Include the purpose of the database and the subject matter it covers. This may be four or five sentences; and

Database model defines the logical structure of the database by determining manner in which the data will be stored. Relational model is one of the most popular database models, which defines tables and relationships between the tables.

Database, it is a place use to store lots of data. It can be seen as a filing cabinet. And database management system (DBMS) is software that specificity designs for managing the data in database such as create, update or delete them. General is including security, retrieval and backup features. User also allows using the data to create a report or share data with multi-user.

An ORDBMS is more advanced than a simple RDBMS since the user can also create reports.

The tables in relational databases organize data in rows and columns, simplifying data access and manipulation. It is easier for manager to understand the relational model than put all data in one table. Besides, a relational database allows tables to be linked. And the linkage reduces data redundancy and allows data to be organized more logically. In a word, relational database is easier to control, more flexible, and more intuitive than approaches.

Evaluate the usefulness and ease of use of maintaining a database with MySQL, compared with

• Entity-relationship modeling is logical representation of the data for an organization or for a business area. The E-R model is expressed in terms of entities in the business environment, the relationship among those entities, and attributes of both entities and their

For this week’s paper I have chosen to do a comparison between IBM’s DB2 database management system (DBMS) product and Oracle. Realistically, making such a comparison is akin to discussing religion with friends. Each person will have their own biases based on their own experiences. Looking for an unbiased opinion is much like looking for the Holy Grail, every bit as speculative and subjective with the results jaundiced by the outlook of the reporter (Lim, 2002).

Firstly a relational database contains a set of tables which basically are linked collectively by the relationships between the tables. Also it is also known as reason such as a database is called relational database.

This paper will compare and contrast five different database management systems on six criteria. The database management systems (DBMS) that will be discussed are SQL Server 2000, Access, MySQL, DB2, and Oracle. The criteria that will be compared are the systems’ functionality, the requirements that must be met to run the DBMS, the expansion capabilities – if it is able to expand to handle more data over time, the types of companies that typically use each one, the normal usage of the DBMS, and the costs associated with implementing the DBMS.

Customer data is scattered and duplicated across multiple systems, making it difficult for sales, marketing, operations, and customer service to have a complete and authoritative view of the critical business information (Shankar, 2013). It is not unusual for retailers to have a set of system, such as point of sale (POS), e-commerce, and a call center, which have different formats to create and store data (Shankar, 2013).

We want to strive to the objective to give the customers a better environment and option to receive the client’s services and products. The database will give more detailed information of orders so that the productivity in the company can increase and therefor keep the customers satisfied and genarate at the same time the maximum profit.

Structured Query Language, commonly referred to as SQL, is a programming language that is used to communicate with and handle databases. In order to maximize the outputs that they get from the huge amount of data collected, many companies and establishments employ IT professionals well-versed in SQL. SQL programs are adopted and used by companies in order to access and influence the data and information that is maintained in their databases, as well as for generating and modifying new tables.
