Choosing A Database Everyday the world progressively moves towards a digital future, and the use of physical data storage, such as files in filing cabinets, are becoming obsolete. Most companies store their information into databases to easily manage and share their data within the organization. A database management system (DBMS) is needed to to create, use and maintain databases for the efficient storage and retrieval of data. Why Choose a Database? Before one can begin to choose a database, it is

Security of NoSQL Database against Intruders Abstract The evolution of distributed web based applications and cloud computing have generated the demand to store voluminous of big data in distributed databases efficiently to offer excessive availability and scalability to users. The new type of database resolves many new challenges especially in large-scale and high concurrency applications which are not present in relational database. These new sorts of databases are not relational by using explanations

What is a Relational Database “A relational database is a collection of data items organized as a set of formally-described tables from which data can be accessed or reassembled in many different ways without having to reorganize the database tables. It was invented by E.F. Codd in 1970.” (TechTarget, 2006) A simpler definition of a relational database is a self-describing group of related tables. There are three ways to modify a table. We can insert a record, delete one, or update a record

Relational Database Management System This type of database management system that stores the data in the form of related tables. It is a social database administrator which deals with some typical kind of queries and uses SQL for the development of the database. This type of database is a very powerful database as it deals with the relations which makes the data manipulations easier other than any other database. It has the features of data entry, data deletion, and creating of new entry and records

P1 Entities: Entities are objects that are located in a data base. Entities allow you to store data objects in the systems data base. These are set out in a table form in the data base. Primary keys, foreign keys, referential integrity and data redundancy are all part of entities. Primary Keys: Primary keys are items that are used to find a record of something on the system with certainty. These files cannot be duplicated and will normally provide a primary key e.g. “autoconters”. Foreign Key:

to a specific data management technology. Without being specific to a particular DBMS product, it describes the data as much as details (Watt and Eng 2014). As we mentioned before, there is another type of DBMS involved in the logical data model such as hierarchical data model and network data model, which will be discussed in the following. 2.2 Hierarchical data models and its products: Hierarchical data model suggests that if the relationships between data in the database are established that

IBM i from other platforms, including its storage, security, and programming models. But one of the most unique aspects of the IBM i platform is its integrated DB2 database, which is used exclusively by practically all IBM i customers. You just dont find this on other platforms. But perhaps its time for IBM i to diversify its database support? In many respects, DB2 for i is the platforms greatest strength. IBM i is renowned for its transaction processing prowess that drives ERP and other line of
