Multimedia database can be understood as the collection of multimedia data which are interrelated and which includes text, images, graphics, animations, audio, and video as well. This database always contains a huge amount of multi source multimedia data. Along with this, you should also understand the multimedia database management system. This database management system is a framework that is behind managing multimedia data.
Because of this multimedia database management system, the user is able to store, utilize, and deliver multimedia data in all different ways.
Classes of multimedia database
There are mainly three classes in a multimedia database. They are:
- Dynamic media
- Static media
- Dimensional media
Multimedia Database management system and contents
Here is a list of contents of the multimedia database system:
- Media data
This is the actual data in this multimedia database which represents the object.
- Media format data
There are many types of formats used and some of them are information like sampling rate, encoding scheme, and resolution. This is all about the format of the multimedia data that it takes after it is encoded, processed, and acquired.
- Media keyword data
This is all about keyword description and it is regarding the generation of the multimedia data. This is also called as content descriptive data. For example, this is all about time, date, and place of the recording.
- Media feature data
This is completely dependent on the content and media features data is all about the distribution of kinds of textures, colors, and all kinds of shapes that present in the multimedia data.
Multimedia Applications Types
These types are actually based on data management characteristics.
- Repository applications
This is a huge amount of multimedia data along with meta-date like Media keyword data, Media format date, Media feature data which is stored mainly for retrieval purposes. For example the respiratory of engineering drawings, satellite images, and radiology scanned pictures.
- Presentation applications
This is about the delivery of multimedia data which is subjected to all kinds of temporal constraints. There is a need that DMBS should deliver data at a specific rate for optimal listening and viewing of multimedia data. It demands the quality of the service at the highest level and this is above the threshold.
In this case, data is always processed when it is delivered, for example, annotating video and audio data. There is real-time editing analysis is another best example of presentation applications.
Collaborative of work by using multimedia information
This always demands the execution of highly complex tasks. This can be tasks like changing the notifications and merging drawings. The best example that we can give for this is an intelligent healthcare network. There are a lot of challenges that the multimedia database face. Let’s look into some of them.
When you are working on the modeling, it is all about improvements in information retrieval techniques and databases. All the documents in this constitute highly need specialized areas.
When it comes to design there is a need to address the multimedia media design completely which is not yet done. There are mainly three design types and they are physical, logical, and conceptual. All these three multimedia databases are yet to be addressed. You can easily find some tuning and performance issues. These issues are present at all levels and they are highly complex to understand. The main reason behind this is, they carry varieties of formats like MPEG, PNG, JPEG, and GIF. These are data formats that are not easy to convert from one form to another.
There are issues with storage as well and they are mainly concerned about handling different forms of multimedia data. There are challenges related to compression, representation, and even mapping. These are needed, to perform archiving, hierarchies and even for buffering mainly in input as well as output operations. But in DBMS, you can make use of Binary large object or BLOB which helps in un-typed bitmaps to get stored and retrieved.
There are many types of features needed like an application that may need to involve video playback and audio-video synchronization. It can also be about physical limitations dominated. There is one solution that you can make use of parallel processing. But this can only solve some problems. So, none of the required technology is completely developed. More than this, the multimedia database always takes a huge amount of time for processing data. It also needs a lot of bandwidth. So, there are many other major issues that are still not addressed.
Multimedia database- Areas of applications
There are many places where a multimedia database is really useful. Mainly in areas where real-time controlling and monitoring is needed, the multimedia database can be utilized. It brings a lot of benefits to these types of systems. More than just the implementation of the multimedia database, it is all about utilizing it in the right way.
Let’s look into some of the major areas where the multimedia database is utilized.
Record and document management
This is the area where industries utilize the multimedia database for keeping their detailed records. The business makes use of multimedia databases for a variety of documents. The best example that we can give for an area where a multimedia database is utilized is an insurance claim record.
This multimedia database is definitely one of the very effective tools. It helps in knowledge dissemination and that results in offering several resources. The best example of this area of utilization is a multimedia database used in electronic books.
Education and training
The multimedia database is very useful in the education field. Through this multimedia database, it is possible to create learning materials that are computer-aided and make use of multimedia sources. This type of source is very popular in the learning field today. Digital libraries are the best example for the usage of the multimedia database in the field of education.
Apart from this, the multimedia database is useful in many other areas like advertising, marketing, entertainment, and even retailing. It is very useful for travel as well. The best example we can give for this area is, virtual tour of cities feature that has been available on the internet today. Multimedia databases can be utilized at its best in real-time monitoring as well as for control. The best example of this is controlling the manufacturing operation in a city.
