Database Models as Explained By Our Experts

According to our database programming experts, a database model is the logical structure of a database including its constraints and relationships that demonstrate how information is stored or accessed. There are many database models used today. Below are the most common ones:

Hierarchical model: In this database model, data is organized into a tree-like structure that contains a single root to which all other data is linked. Just as the name suggests, the hierarchy starts from the original data (Root data) and spreads like a tree with nodes and parent nodes. In this model, each child node has only one single parent node. Hierarchy model only provides for one-to-many and one-to-one relationships, but not many-to-many. A good example of such a model in real life is a department that has many courses, many students, and of course many professors.

Network model: This is basically an extension of hierarchical model whereby information is organized more like a graph. In this model, child nodes usually have more than one parent node. In network model, information is more related because there are many relationships established. Also, since data is related, accessing it gets much faster and easier. This database model is used to map many-to-many relationships.

Relational model: This is the most commonly used database model today. It was developed to overcome the inflexibility and complexity of the hierarchical and network database models. The relational model consists of unique tables that are composed of fields and records. One field in each table can be chosen as the primary key. A primary key is a unique value that is used to distinguish a certain record from other records within a specific table. The most common relational database management systems include MySQL, Microsoft SQL Server, and Oracle.

Object oriented database model: Although relational database models have a wide range of applications, they do not support the distribution of databases across multiple servers. For this reason, object oriented database models were developed. With the object oriented database model, users can define the method by which they want to access, represent, and manipulate data.

Applications of Databases

Databases are used in almost everything we do today. Some of the most common applications include:

• Banking: – To store customer and accounts information, process loans and perform other banking transactions
• Academic institutions: – To carry out student registration and store grades
• Online shopping: – Nowadays, we all want to shop from home. A database management system allows online stores to add and sell products, store customer billing information, and process payments.
• Airlines: – To manage reservations and flight schedule information
• Libraries: – To maintain information related to the name of the book, author, availability and book issue dates.
• Telecommunications: – To store records of the calls made, generate monthly bills, and maintain balances on calling cards
• Sales department: – To manage purchase, products, and customers information
• Finance: – To maintain information about sales, purchases of stocks and bonds, and holdings
• Manufacturing: – To store supply chain information, track the production of products in factories, and manage inventory of items
• HR department: – To store employee, salary, taxes, benefits, and payroll information.

Advantages of Database Management Systems

Controlling data redundancy: Data redundancy is simply duplication of data. Database systems have a centralized database and control of data, which avoids unnecessary duplication of data, hence saving the storage space. Having a centralized database also eliminates the extra time used to process large volume of data.

Data integrity: A centralized control of data allows database administrators to define integrity constraints on data in the database. For instance, one can enforce integrity in a customer database such that only customers from a certain region are accepted.

Security: By having complete authority over data, a database administrator is able to secure information by ensuring that data is accessed only through proper channels.

Data consistency: By eliminating redundancy, one is able to greatly reduce chances of inconsistency. In addition, accessing and updating records gets very easy when everything is stored in one place.

Improved data sharing: In database management systems, information is stored in structured tables that are designed to provide different levels of user access, based on user needs. As such, a piece of data can be accessed or shared by multiple users at the same time.

Disadvantages

• Database management systems require high skilled personnel and sophisticated hardware and software, which may be costly to maintain. The cost of regulation compliance, licensing, and personnel training can be substantial too.
• To ensure that the database operates efficiently, one must keep the system up-to-date by applying the latest patches to all components. As a result, a company would be required to invest heavily on technology, a practice that is quite expensive.
• In many organizations, all data is stored in a single database. In the event that the database is corrupted due to viruses or power failure, then the organizations may be at a risk of losing valuable information. To avoid this there must be a data mirroring facility which leads to further cost escalation.

Database Languages

A database language is used to read, store, and update information in a database. There are two main languages that can be used for such purposes:

Data Definition Language (DDL): This is used to classify the database schema or structure. This language allows the database administrator to name and depict relationships, attributes, and entities that are required by an application along with any associated security and integrity constraints. Common tasks that fall under DDL include:

• CREATE: – to create objects in a database
• ALTER: – to change the structure of the database
• DROP: – to erase objects from the database
• COMMENT: – to include comments in the database programs
• RENAME: – to rename an object in the database

Data Manipulation Language (DML): This language offers a set of instructions to perform the basic data manipulation techniques on the information held in the database. Common tasks performed under DML include:

• INSERT: – to insert data into a table
• SELECT: – to retrieve data from the database
• DELETE: – to delete records from a table, but the spaces allocated for the records remain
• UPDATE: – to update existing data within a table
• MERGE: – to INSERT an operation
• LOCK TABLE: – to control concurrency
• EXPLAIN PLAN: – to explain access path to data

Elements of a Database

The most important elements of a database include:

Database schema: Simply put, a schema is a group of common or related objects in a database. Related objects often have relationships to one another within a schema. A schema is usually assigned one owner who has full access to any object in the schema.

Table: This is the primary unit of a physical location where data is stored in a database. Tables are linked with each other using relationships.

Columns:  Also known as a field, a column is a specific category of data that exists within a table. Columns represent related parts of a table and are the smallest logical structures of data storage in a database.

Rows: A row is the collection of all columns in a table. It is usually a single record in a table.
