Database Management

Database Management

Every system revolves around data – in one form or another. Today, there are a large number of options to collect, store, index, search, retrieve and convert data on a continuous basis. Different systems have different database requirements – and software designers have to taken into consideration various factors such as load, volume of records to be managed, data formats, query performance, etc.

Our database management courses are aligned to help course participants understand database fundamentals beyond what is taught at the college level and prior to that. The courses focus on providing the guidance to all participants so that they can go deep into database management and administration if they so desire.

We have different courses available targeted towards participants with different skill sets, and also based on the nature of applications and data access requirements.

Our courses include coverage of the storage mechanisms and formats, and data organization principles as listed below:

A DBMS always provides data independence. Changes in storage mechanism and formats can be made without modifying the entire application. There are four main types of database organization:

    • Relational Database: In this model, Data is organized as logically independent tables, with relationships among tables shown through shared data. Integrity of the links between tables is maintained with the data in one table possibly referencing similar data in other tables – referential integrity – an important concept in a relational database system. These tables can be queried using “Select” and “Join” Operations. Relational Databases have been used widely in enterprise systems and applications.
    • Flat Database: Data is organized as a group of one kind of record with a fixed number of fields. Due to the repetitive nature of data, data integrity can be compromised in this format.
    • Object-Oriented Database: Data is organized along the lines of object oriented programming concepts. Just like an object consists of data and methods, and classes group similar objects, the data in Object oriented databases are stored with similar associations.
    • Hierarchical Database: Data is organized with hierarchical relationships. This type of database can quickly lead to a complex network if the one-to-many relationship is violated.
