...Big Data Big Data and Business Strategy Businesses have come a long way in the way that information is being given to management, from comparing quarter sales all the way down to view how customers interact with the business. With so many new technology’s and new systems emerging, it has now become faster and easier to get any type of information, instead of using, for example, your sales processing system that might not get all the information that a manger might need. This is where big data comes into place with how it interacts with businesses. We can begin with how to explain what big data is and how it is used. Big data is a term used to describe the exponential growth and availability of data for both unstructured and structured systems. Back in 2001, Doug Laney (Gartner) gave a definition that ties in more closely on how big data is managed with a business strategy, which is given as velocity, volume, and variety. Velocity which is explained as how dig data is constantly and rapidly changing within time and how fast companies are able to keep up with in a real time manner. Which sometimes is a challenge to most companies. Volume is increasing also at a high level, especially with the amount of unstructured data streaming from social media such as Facebook. Also including the amount of data being collected from customer information. The final one is variety, which is what some companies also struggle with in handling many varieties of structured and unstructured data...

...Smith Consulting Database Environment Student Name DBM/380 Date: Instructor name: Smith Consulting Database Environment Smith Consulting’s current employee management system is inefficient involving a one table database, which produces duplication of many attributes throughout the system. The first iteration of database design provided a new version consisting of various one-to-many relationships to link its various modules. There are currently four modules that consist of an employees, jobs, skills, and projects tables. Smith Consulting has many employees filling many jobs descriptions. Furthermore, each job position may encompass many skills. Finally, many employees may be working on many projects. This first iteration of database design provided a database model that is inadequate and requires a return to the database development life cycle (DDLC) to incorporate the needed many-to-many relationships among tables for efficient allocation of human resources in order to better meet company customer needs. An analysis of the database environment has surfaced the various problems and constraints with the current system. This in turn has determined the scope and boundaries for the new system version. An overall objective and supporting objectives provided the needed data specifications, which is depicted in a logical model table and database schema. Database Environment Analysis The current database environment involves a one table database. This current system has various...

...DBMS vs. RDBMS • Relationship among tables is maintained in a RDBMS whereas this not the case DBMS as it is used to manage the database. • DBMS accepts the ‘flat file’ data that means there is no relation among different data whereas RDBMS does not accepts this type of design. • DBMS is used for simpler business applications whereas RDBMS is used for more complex applications. • Although the foreign key concept is supported by both DBMS and RDBMS but its only RDBMS that enforces the rules. • RDBMS solution is required by large sets of data whereas small sets of data can be managed by DBMS. 1. What is database? A database is a collection of information that is organized. So that it can easily be accessed, managed, and updated. 2. What is DBMS? DBMS stands for Database Management System. It is a collection of programs that enables user to create and maintain a database. 3. What is a Database system? The database and DBMS software together is called as Database system. 4. What are the advantages of DBMS? I. Redundancy is controlled. II. Providing multiple user interfaces. III. Providing backup and recovery IV. Unauthorized access is restricted. V.

...In order to accommodate for , and mitigate against the risk of database configuration and implementation mismatch( see risk priority 1), the development team must be able to provide the following: 1. Specific documentation stating what database software is supported by the RMT. 2. Generate and apply specific tests against supported RDBMS. 3. Provide configuration examples for the supported RDBMS software 4. Work with client, and provide support for RDBMS software that is out of scope for integration. 5. Generate scenarios in documentation that explains “like” configurations of the databases. By enforcing a rigid set of examples and tests against the supported RDBMS software, working with the client to ensure that these match specific requirements for development, and providing helpful support when the issue may arise, much of this risk is mitigated by providing a specific path on how to compensate for the risk. 6. Technical Process Plans This section addresses the processes and mechanics behind the RMT development team’s plans to analysis, construct and test the source code based on the client’s needs. 6.1 Process Model...

...with RDBMS: As far as data modeling is concerned, OODBMS deals with objects while RDBMS deals with entities. The important features of OODBMs are: 1. Building up of complex objects from simpler ones by application of constructors that represent collections, attributes and relations, and order. 2. The objects in OODBMs have identities independent of their values so that there is a considerable equality and distinction between any two identical objects that point to exactly the same data structure in allocated memory. 3. The objects can be encapsulated i.e. only the operations specified in the interface can be performed on objects by applications and the interface contains hidden implementations which are inaccessible by the applications. 4. Provides database garbage collection i.e. it helps in keeping external programs from having to track the use of object pointers. Next, the main features of RDMS (Relational Database System) are: 1. Efficient secondary data storage management 2. Data provided to be stored is arranged in tables. 3. Data is indexed for quick retrieval of data. 4. A facility primary key is provided to uniquely identify the desired rows. When to Use Object Databases & When Not To? Object databases should only be used when there are complex data relationships. Such relation comprise a many-to-many object relationship. Object databases should not be used when there would be fewer joint tables or large volumes of a simple transactional data.

...Database Design: Relational Database Management Systems Marvin E. Eubanks CIS111: Introduction to Relational Database Management Systems Strayer University Professor: Emelda Ntinglet-Davis November 22, 2011 Introduction Regardless of the size of a company or business, the employees are usually considered the most important asset. However, data should rank equally important as the employees do. It is very vital that a company’s data is stored and maintained as accurately and as quickly as possible. Having a Database Management System allows a business to do just this. Database Management System (DBMS) Webopedia (2011), states it simply: “A DBMS is simply the software program on a computer that is used to store and manipulate data.” Manipulation of data consists of adding new data such as adding personal information about an employee; deleting unwanted data such as deleting the personal information of an employee who has quit or been terminated; or changing existing data such as changing the pay rate of an employee who has been promoted. Advantages to having a DBMS are it aides in data security, data integrity, data sharing, data concurrence, data independence, and data recovery to name a few. Database management systems are important because it allows businesses to manage data more efficient and effective; query language allows quick responses to ad hoc queries; improves access to more data; and reduces the chance that data will be inconsistent. Features...

...System). The second approach was based on the network data model, which its main aim of creation was to create a standard database that would unify number of functionalities such as programming languages (queries) for data retrieval, and the inability of the existing database to represent complex relationships database management systems (DBMS). However, these two models had some fundamental disadvantages: • Complex programs had to be written to answer even simple queries • There was minimal data independence • There was no widely accepted theoretical foundation. In reference to DBMS and the ability of building complex relational system, many Relational database management system RDBMS has been developed (also referred as a second generation of DBMSs). RDBMS was used extensively in the 80’s and 90’s, however due to its limitation to respond the more complex entity and, needs of companies and the increasing complexity of database applications. Two “new” data models have emerged; the Object-Relational Database Management Systems (ORDBMS) and Object-Oriented Database Management Systems (OODBMS), which subscribes to the relational and object data models respectively. The OODBMS and ORDBMS have been combined to represent the third generation of Database Management Systems. Current trends of database model: 1. Distributed databases: Distributed databases are the most...
