DATABASE ASSIGNMENT HELP

A Database is a collection of data stored in a well-organized fashion for ease of retrieval and manipulation. The process of storing, manipulating and retrieval of this data is mainly via a computer system and the software that aids the computer to do all that is referred to as a Database Management System (DBMS).

Assignments relating to the creation and management of Databases have proven to be confusing for many students, most of whom end up with poor performance each time they encounter a Database assignment. Nonetheless, these students can’t entirely be blamed for their dismal performance because Database as a study unit is very wide and students can’t be experts just after 3 months of study.

Breakdown of Databases

Classification of Databases come in 4 broad perspectives. Computer scientists can classify Databases according to the type of data held in the Database, their area of application, the Database structure, and the Database model. Classifying Databases according to their models is the most popular mainly because it gives an easy avenue of developing Database Management Systems.

From the first three classifications, we have the following types of Databases:

Active Databases	Graph Databases
Cloud Database	Hypertext/Hypermedia Databases
In-memory Databases	Mobile Databases
Distributed Databases	Operational Databases
Embedded Databases	Parallel Databases
Real-time Databases	Deductive Databases

When it comes to Database classification according to the models, we have the following Databases which are common:

• Hierarchical Database Model: In this Database model, data is organized in a tree-like structure and stored as records. These records are then connected to one another through links. In this Database, data is accessed on a one-to-many relationship and it is very predictable.
• Network Database Model: Unlike the hierarchical model which is based on a one-to-many principle, the network model allows each record to have multiple parent records and multiple children as well. This kind of relationship is referred to as a many-to-many relationship.
• Relational Database Model: First explained by Edgar Codd in 1969, this model the most commonly used today. In a relational Database, the idea is to describe the Database as a collection of one or more relations. The main advantage of this model is its simplicity and elegance.
• Entity-Relationship Model: The entity-relationship model describes gives a basic relationship of objects in a specific domain. Mainly used in the early stages of Database development, this model depicts real-world objects as Databases entities and specifies the relationship that can exist between two or more entities.
• Object Database Model: Unlike Relational Databases that present information in form tables, in this model, information is represented in the form of objects; just like in object-oriented programming.

Apart from the above, other common Database models are:

• Star Schema
• Flat file
• Inverted index
• Associative model
• Multidimensional model
• Multivalue model
• Semantic model, etc.

Overview of DBMS

As earlier mentioned, accessing and managing data in a Database is carried out with the help of a Database Management System. This is a software package through which users can define, update, retrieve and manage data stored in a Database.

The Relational Database Management Systems (RDBMS) are among the most popular ones today and implementation and use of these Databases require a good mastery of SQL. SQL is the standard language of Database management and over 80% of the Databases you will encounter will require knowledge of SQL.

Some of the commonly known DBMS include:

Microsoft SQL server	MySQL
dBase	LibreOffice base (for Linux) and Microsoft Access for Windows
MariaDB	Oracle
mSQL	IBM DB2

As a student, you may not be good at SQL and dealing with these Databases may be a great challenge. Facing an assignment on this? You don’t have to worry because experts at All Homework Assignments got you covered. With our help, you can be sure of excelling in any Database homework because we are the masters of Database management.
