Comparison of RDBMS with OODBMS:
Choosing between these options need to have a closer look at some different aspects. The main keywords are development, performance and access to different sources (it’s possible that more than one application needs the same data source). The last one is a necessary point for DreamHome company, because all the different offices can have different applications and need the data from the same database.
The performance of the Database is concerned on the structure of the data. An application that navigates though the data like following links will be more efficient if it uses an Object oriented DB. If you have to process the data sequentially or have a complex query to get the data, the relational DB is faster. So in fact the data structure of the DreamHome company will not be extremely complex because in the shared database there will be some information about the owner, the clients, the properties they want to rent, the furniture and the services the owners and clients want to occupy.
Advantages of implementing OODBMS:
Most OODBMS have implemented a reachability persistence which is a big advantage at complex data relationship especially complex object relationship. Reachability persistence means that if an object is stored to the database, the object references the first one is also stored.
The depth of the reachability persistence can be specified by the programmer; so whole bundles of objects can be fetched with a single call. The details like references between the stored objects are handled by the Management system. Such object structures can be found at a tree with parent, child, grandchild and so on. In this situation there is no need to change the original structure of the data to a model. P...

...y exists to create new tables by joining already existing tables. But it is not possible to “join” two classes in an OODBMS. An Object Oriented Database Management system highly depends on the design of the system.
Problem areas implementing an OODBMS within the organization:
New applications have to be implemented, which can store and fetch the data into and from the OODBMS which may include some extra costs for DreamHome company. Another possibility is to search for free standard tools which can handle the data exchange with the Object Oriented Database Management System.
Conclusion:
Nowadays most of the applications connected to a database use the relational standard but recently the Object Oriented Database Management System becomes more important and it is expected that many companies like DreamHome research the advantages of OODBMS and implement this solution.
The next project deliverable is a robust, modernized database and data warehouse design. The company collects large amounts of website data and uses this data to analyze it for the company’s customers. This document will provide an overview of the new data warehouse along with the type of database design that has been selected for the data warehouse. Included in the appendix of this document is a graphical depiction of the logical design of the
The common element of the open source databases is the use of share data of student information. The common features used by the databases are their operating systems UNIX or Windows, as well as MYSQL database. The database used b...
Internal schema at the internal level to describe physical storage structures and access paths, typically uses a physical data model.
The factors listed though impressive and quite thorough, lacks in three crucial factors we believe would make a deep influence in choosing a provider. They are future scalability and expandability, flexibility to adapt to probable changes during development and maturity of technology being used. Elaborating on why the above stated factors are important to be considered during the selection process, we believe that sufficient forethought and foresight needs to be put on to predict future demand and load on the software and evaluate if the provider can handle these predicted future requirements by upgrading and scaling their system. With a focus on agility, the SiL’K team needs to ensure if the providers are flexible enough to accommodate a change if one arises outside the scope of the initial requirement specification. This is more of a qualitative assessment. Lastly, the third factor stresses on evaluating the technology used in the provider’s implementation. Care must be taken to ensure though the technology can meet the current needs, it is of the modern age and has sufficient maturity to evolve over a period of time to enjoy advantages of new, upcoming enhancements.

It assumes an important role in terms of cost reduction for the entity given that it results in the reduction of the number of personnel that would be tasked with maintaining and securing the in-house database and systems. Labor and subsequent resources usually result in higher costs of operation within the entity, which in turn hurts the profit margins and possibly the strategic objectives, and goals of the organization (Hallows, 2002). In essence, the new organizational structure demands the presence of an appropriate network design that will accommodate an increased number of individuals within the proposed workspace, as well as enhanced improvements in security protocols for the system. Cloud technologies with overseas or outside management provide effective and efficient options for reducing the downtimes from network failure and other crises such as damaged equipment and infrastructure. A hosted hybrid solution provides one of the safest systems for organizational needs than other forms of systems.
This paper was written to show the similarities and differences in five different databases. It compared Access, MySQL, SQL Server, DB2, and Oracle in six different areas. It found many similarities in functionality, but large diversity in pricing.
These structures could look similar to a relational database, but others look completely different. Depending on the specific structure used, your choice of Database Management Systems will change as well. There are four common data models to use: Key/Value Stores, Document Databases, Table-Style Databases, and Graph Databases (Data Access for Highly Scalable Solutions). Key Value Stores Looking at the different data storage models, this is the most simple to implement. This is a way to have a schema-less design for storing data.
The database application design can be improved in a number of ways as described below:
The multi-tenant applications by Saas will helps in reducing the cost, as every customers uses the common database through encapsulation. While locally hosted service will produce different database for each customer which will increase the load on system.
Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.
Oracle's relational databases represent a new and exciting database technology and philosophy on campus. As the Oracle development projects continue to impact on University applications, more and more users will realize the power and capabilities of relational database technology.
The Database Management System (DBMS) is software that enables the users to define, create, maintain and control the access to the database. It is a software that interact with the user’s applications programs and it database. Meanwhile, information retrieval system is a system that involved the activity that the systems obtain the information. The obtaining information action need the information from it resources.
These basic rules allow user defined as well as built-in data types to define information which allows the schema to be extensible just as XML itself. (N/A, 2001). With these basic structural boundaries in the Schema benefits noted are; (N/A,2001)
In our world, people rely heavily on the power of technology every day. Kids are learning how to operate an iPad before they can even say their first word. School assignments have become virtual, making it possible to do anywhere in the world. We can receive information from across the world in less than a second with the touch of a button. Technology is a big part of our lives, and without it life just becomes a lot harder. Just like our phones have such an importance to us in our daily lives, database management systems are the same for businesses. Without this important software, it would be almost impossible for companies to complete simple daily tasks with such ease.
