Multidimensional Data Model

What is a data cube? A data cube allows data to be modeled and viewed in multiple dimensions. It is defined by dimensions and facts. In general terms, dimensions are the perspectives or entities with respect to which an organization wants to keep records. Each dimension may have a table associated with it, called a dimension table, which further describes the dimension. Facts are numerical measures. The fact table contains the names of the facts, or measures, as well as keys to each of the related dimension tables. Example: 2-D representation, the sales for Vancouver are shown with respect to the time dimension (organized in quarters) and the item dimension (organized according to the types of items sold).

Database Users and User Interfaces

There are four different types of database-system users, differentiated by the way they expect to interact with the system. Different types of user interfaces have been designed for the different types of users. Naive users are unsophisticated users who interact with the system by invoking one of the application programs that have been written previously. For example, a bank teller who needs to transfer $50 from account A to account B invokes a program called transfer. This program asks the teller for the amount of money to be transferred, the account from which the money is to be transferred,and the account to which the money is to be transferred. As another example, consider a user who wishes to find her…

Different Types of Database management systems

A Database is a collection of records. Database management systems are designed as the means of managing all the records. Database Management is a software system that uses a standard method and running queries with some of them designed for the oversight and proper control of databases. Types of Database Management Systems: There are four structural types of database management systems: * Hierarchical databases. * Network databases. * Relational databases. * Object-oriented databases Hierarchical Databases (DBMS) : In the Hierarchical Database Model we have to learn about the databases. It is very fast and simple. In a hierarchical database, records contain information about there groups of parent/child relationships, just like as a tree structure. The structure implies that a record…

Entity-Relationship Diagrams

Data models are tools used in analysis to describe the data requirements and assumptions in the system from a top-down perspective. They also set the stage for the design of databases later on in the SDLC. There are three basic elements in ER models: Entities are the “things” about which we seek information. Attributes are the data we collect about the entities. Relationships provide the structure needed to draw information from multiple entities. Generally, ERD’s look like this: adapted from another professor. Developing an ERD Developing an ERD requires an understanding of the system and its components. Before discussing the procedure, let’s look at a narrative created byProfessor Harman. Consider a hospital: Patients are treated in a single ward by…

Informatica: What are the kinds of lookup?

You can configure the Lookup transformation to perform different types of lookups. You can configure the transformation to be connected or unconnected, cached or uncached: Connected or unconnected. Connected and unconnected transformations receive input and send output in different ways. Cached or uncached. Sometimes you can improve session performance by caching the lookup table. If you cache the lookup table, you can choose to use a dynamic or static cache. By default, the lookup cache remains static and does not change during the session. With a dynamic cache, the Informatica Server inserts or updates rows in the cache during the session. When you cache the target table as the lookup, you can look up values in the target and insert…

Patient Recording System

The system supplies future data requirements of the Fire Service Emergency Cover (FSEC) project, Fire Control, fundamental research and development. Fire and Rescue Services (FRSs) will also be able to use this better quality data for their own purposes. The IRS will provide FRSs with a fully electronic data capture system for all incidents attended. All UK fire services will be using this system by 1 April 2009. Creation of a general-purpose medical record is one of the more difficult problems in database design. In the USA, most medical institutions have much more electronic information on a patient’s financial and insurance history than on the patient’s medical record. Financial information, like orthodox accounting information, is far easier to computerize and…

Individual Database Design

“A database is a structured collection of records or data that is stored in a computer system. In order for a database to be truly functional, it must not only store large amounts of records well, but be accessed easily. In addition, new information and changes should also be fairly easy to input (tech-faq. com)”. To ensure practical use over a long period of, databases ought to be built with high-level of data integrity and the capability to recover data in the event of hardware failure. Data that has been destroyed or corrupted is useless within a business’s data system structure. The database architecture is the set of specifications, rule, and processes that dictate how data is stored in a…

Vendor Database

As you recall, data is a collection of facts (numbers, text, even audio and video files) that is processed into usable information. Much like a spreadsheet, a database is a collection of such facts that you can then slice and dice in various ways to extract information or make decisions. However, the advantage and primary use of a database over a spreadsheet is its ability to handle a large volume of data and yet allow for quick access to the information that is desired. Databases are everywhere now and impact our lives in a multitude of ways. It can accurately be said that “your life is in a database” or, more accurately, in multiple databases, and information about you (a…

System Proposal for Riordan Manufacturing, Inc.

Introduction In reviewing the current and historical sales and marketing information for Riordan Manufacturing, Inc., it became clear that there is a need for a new streamlined system to track the past and present workings of the company. There are past marketing plans being stored in one location in a file cabinet, limiting the personnel that has access to it (Riordan Manufacturing, Inc., 2012). Sales employees are using different methods to track their numbers, in some cases using pencil and paper (Riordan Manufacturing, Inc., 2012). We propose a new cloud based system that will compile all of the past sales and marketing information and current customer contacts and needs. This system will allow employees from all areas and locations access…

Database Management

In his book Groupware — Computer Support for Business Teams, Robert Johansen defines groupware as “specialized computer aids that are designed for the use of collaborative work groups.” This definition is better than the “shared data” definition because it helps eliminate multiuser databases from the groupware category. Yet electronic mail fits this definition, as well as some other software sharing tools that experts are still debating. A more useful definition also appears to be one of the oldest. Peter and Trudy Johnson-Lenz are credited by many as coining the term groupware in 1978. They defined it as “intentional group processes plus software to support them.” Groupware enhances collaboration by allowing by the exchange of ideas electronically. All the messages on…

Information Literacy

Why is it important to understand the difference between computer literacy and information literacy? Information literacy differs from computer literacy in that information literacy is the ability to organize and analyze data whereas computer literacy simply pertains to the ability to use computer software or hardware. Information literacy goes far beyond the simple technical knowledge of being able to use a computer. It is important to understand the difference between the two because of the importance of information literacy and the benefits an individual and an organization can derive from such knowledge. Information literacy includes computer literacy as well as information finding, information understand, value creation and sharing of information with others. (Nishimuro, 1999. ) Information literacy contributes to the…

Thesis Documentation of Library System

The design of the existing MLS curriculum was last revised in 1986. It was based on the old/traditional way of library operations. Recent developments in technology have however radically changed the format of information sources, the way of seeking, accessing and delivering information and of the learning styles. It has also brought about the existence of other alternative information providers serving as competitors of the library in the information market place. More so, the capabilities and capacities of technology have increasingly transformed libraries into a virtual place. The expectation of the 21 st century setting has expanded the role of librarians from mere passive custodians of library materials to librarians with knowledge of computer database and library automation systems. Today’s…

Seerat Un Nabi

Chapter one Distributed database system (DDBS) technology is the union of what appear to be two diametrically opposed approaches to data processing: database system and computer network technologies. Database systems have taken us from a paradigm of data processing in which each application defined and maintained its own data to one in which the data are defined and administered centrally. This new orientation results in data independence. The working definition we use for a distributed computing system or a distuributed processing database states that it is a number of autonomous processing elements (not necessarily homogeneous) that are interconnected by a computer network and that cooperate in performing their assigned tasks. The “processing element” referred to in this definition is a computing…

Library Science

An integrated library system (ILS), also known as a library management system (LMS),[1][2] is an enterprise resource planning system for a library, used to track items owned, orders made, bills paid, and patrons who have borrowed. An ILS usually comprises a relational database, software to interact with that database, and two graphical user interfaces (one for patrons, one for staff). Most ILSes separate software functions into discrete programs called modules, each of them integrated with a unified interface. Examples of modules might include: acquisitions (ordering, receiving, and invoicing materials) cataloging (classifying and indexing materials) circulation (lending materials to patrons and receiving them back) serials (tracking magazine and newspaper holdings) the OPAC (public interface for users) Each patron and item has…

Database systems are the spinal cord of any health care organization. It can be define as the collection of health data. The use of such systems has improve the health care system for decades helping set standards and even regulations to help the system be more efficiently productive. There are different database architectures available to meet the needs of each organization individually. There is a need for the continuum of database across the health care system. Definition A database is a structure that can store information about multiple types of entities, the attributes of those entities, and the relationships between the entities (Pratt & Adamski, 2012, Chapter 1). How data is received, stored, processed, and made available to others has…

History of Database

Storing data and files is an important aspect of business for various industries of the world. The storage of data in computers or database system is proven to be cost effective. Large or small database needs a system which will control the processes in the databases. Such applications are called database management systems (DBMS). From the time it was designed, the need for a good DBMS has increased because of the escalating number of data stored in the database. There are many available DBMS that private corporations use today. Indeed, database management systems have evolved due to the demand for the services that these systems provide.
