Object-Oriented Database Management Systems The construction of Object-Oriented Database Management Systems started in the middle 80's, at a prototype building level, and at the beginning of the 90's the first commercial systems appeared. The interest for the development of such systems stems from the need to cover the modeling deficiencies of their predecessors, that is the relational database management systems. They were intended to be used by applications that have to handle big and complex
Relational and Object-oriented Database Management Systems A database is a “shared collection of logically related data designed to meet the information needs of multiple users in an organization” (Hoffer 709). Databases contain data records or files, such as sales transactions, product catalogs and inventories, and customer profiles. Databases allows multiple users in an organization to easily access, manage, store, and update data when needed. A database management system is software
merging object oriented programming ethics with database management ethics. Object oriented programming concepts such as encapsulation, polymorphism and inheritance are imposed as well as database management concepts such as the ACID properties (Atomicity, Consistency, Isolation and Durability) which show the way for system reliability, it also supports an ad hoc query language and secondary storage management systems, which is allocated for managing very large amounts of data. The Object Oriented
interactivity. The inclusion of multimedia learning objects in online or blended course design often enhances how students process information by appealing to the multiple ways students learn and giving them opportunities to test or practice their understanding of content. What is a Learning Object? Essentially, a learning object is a tool that instructors can use to teach a particular topic and address a specific learning objective. A learning object can be considered to be a single, self-contained
The Database 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
Differentiate between database management system and information retrieval system by focusing on their functionalities. In short Database Management System is knows as DBMS. DBMS is a system that is uses a standard method of cataloguing, retrieving and running queries data. The DBMS operate to manage incoming data, then organizes it, and provides ways for the data to be modified or extracted by users or other programs. Information Retrieval System or IR is finding material (usually documents) of
application in the real world needs to interact with databases. Java Database Connectivity (JDBC) is the Application Programming Interface (API) used to build Java applications that can interact with relational databases. There are many relational databases such as Oracle, My SQL, DB2, Java DB, Dbase, Sybase, Ingress, Informix, FoxPro and so on. The researcher will be able to use the four types of JDBC drivers to interact with any kind of database in the world. In this iteration, the researcher also
Within the past decade, there has been a tremendous growing need for web servers and databases; also their related service and the two concepts have hit the headlines as the most researched knowledge domains in the technology sphere. Subsequently, this has revolutionized the way many people interact with one another through effective information sharing. This rapid spread and the management effectiveness of advanced technologies are establishing great opportunities for development of distributed
Java language is currently one of the most popular programming languages being used. Java language is an object-oriented programming language was developed by James Gosling in 1995 at Sun Microsystems that can be run on many different operating systems (Wikipedia, 2015). It is also known as high-level language because it is easier for humans to read and write
A database is an ordered collection of data that usually can be accessed through many different ways. A databases most important function is retrieving information. But Databases also have many other functions pertaining to information, including being able to sort, store, and locate information. The easier a database can access information the more effective the database is. Most of todays complex databases are found on a computer. SQL is the Structured Query Language. A database and SQL help communicate
Since the SQL language appeared in mid 1970s, it has been leading the relational database industry for many years. With the modern era of databases not everyone sees the advantages of using relational databases. NoSQL, was first developed in the twenty first century (MongoDB, para 19) to address the issues that the SQL language could not handle. NoSQL cannot handle pure relational database models, it can use any of five different kinds of models, including relational to solve problems. With the variety
concerned with organizing information. In other terms, IR is emphasizing the range of different materials that need to be searched. Others researcher said that IR is the contrast between the strong structure and typing a database system with the lack of structure in the objects typically searched in IR. The actual process in information retrieval systems is it has to deal with incomplete or under specified information in the form of the queries issued by users. IR uses the techniques of storing and
to NoSQL For storing the data in organized manner we use the traditional relational databases and in these databases the information is stored in the form tables. NoSQL is an abbreviation or a short form for ‘Not only SQL’. Carlo Strozzi in 1998 for the first time used this name to refer their open source relational database, which didn’t exposed its SQL interface. As this was different from the relational databases so on later stage he suggested to name it NoRel (No Relational) instead of NoSQL (Not
track of who has books and who doesn't, she also needs to be able to do this quickly and with ease. Possible solutions ================== Her possible solutions are: creating a database, a spreadsheet, a manual card system, or a written list of who has what. Disadvantages ============= Database and spreadsheet - Computer could break and information will be lost, someone could also hack into the system, also, if the system got a virus then the information could become damaged
Decision Support System (DSS) is an information system at the management level of an organization that combines data, analytical tools, and models to support semistructured and unstructured decision-making. A DSS can handle low volume or massive databases optimized for data analysis. DSS has more power than other systems. They are built explicitly with a variety of models to analyze data or they condense large amounts of data into a form where they can be analyzed by decision-makers. DSS are designed
Data Manipulation Language Data Manipulation refers to data retrieval from the database, data insert into database, modify data of the database and delete data from the database. Since these operations can manipulate data in the database, the language is called as Data Manipulation Language. There are two main types off DMLs. They are as follows: 1. A high-level or procedural DML can be used to specify complex database operations concisely. 2. A low-level or procedural DML must be embedded in a general-purpose

data at rest. This paper focuses on Database encryption for database security, different methods and levels of database encryption and its advantages over other methods of data protection. It also discusses on the performance issues associated with data encryption and best practices to minimize the performance over head on the database server due to encryption. 2. Database security - Encryption: Database security is securing the data on a centralized database against the compromises of their confidentiality
: What is the "A" in ACID database properties? Give an example of the use of this property and what might happen if the property is not met A: The “A” in ACID database properties represents Atomicity. Atomicity is described easily using “all or nothing” i.e, if we consider that the database processes the transactions either it should be fully completed or not at all done. If a single task in a transaction fails then the whole transaction fails. According to this ACID rule, Let us consider two
records list the contact details of residents, their Medical Administration Record (MAR) and accident/incident records. Designing the record around the database makes it easier for staff to sort out and identify, for example, all residents who are taking controlled medications or whose risk assessment needs closer observation by internal staff. A database application will also help HB to reduce the overall burden of the traditional paper method and will e... ... middle of paper ... ...nce an incident
