What Is Java Used for on a Computer?In Feburary 2016 27,

In Feburary 2016 27,
On both PCs and the Internet, Java programs provide entertainment. Java is a common language for building gaming experiences, with the full range of computer games implemented using the platform. Developers and organizations also use Java to create entertainment software and websites, including those for watching video, listening to music and interacting with website content. Entertainment sites use Java in a number of ways, such as modeling and connecting to databases at the 'back end' as well as providing user interaction at the 'front end.'
Office
Whatever you use office software for, whether for business or domestic purposes, the programs you use may be written in Java. Java programs for office use include word processing and spreadsheets. The open source system, Open Office, uses Java and is a popular example of how flexible the platform is. One main advantage to the Java language is that it is portable, meaning that developers can write Java programs once, and they will be compatible with a number of different operating systems when executed.
Organization
Java applications provide organizational tools, including calendars, electronic communications, such as email, and even Web browsing. There are many open source Java applications for productivity, including personal organizers, to-do lists and mind mapping tools. When people browse the Web, using on-line tools for organization which are implemented in Java, the Java Runtime Environment installed on their computer allows these functions to operate.
Databases
Java provides a range of resources for database applications; it is therefore often the basis for such software. Developers can use Java to create user interfaces to connect to data sources without having to implement these connections within their own code, as the language provides ready-made resources for it. Java applications can therefore make connections to, as well as query and process results from, popular database management systems over a network, including Oracle and MySQL.
Programming
For most users, Java is a tool that enables the software they use to function, but it remains relatively remote from their own interaction. However, for developers, the Java installation on a computer is what allows the Java programming itself to be carried out. The main tools developers use to create Java applications are included within the Java Development Kit, which includes the JRE. There are also many development tools for Java, including Integrated Development Environments, such as Eclipse and NetBeans.

The Responsibilities for a GIS DBAIn Feburary 2016 23,

In Feburary 2016 23,
In addition to requisite database administration skills, GIS DBAs need to possess some knowledge on geographic information systems. These skills namely include geographic knowledge, but not just placement of states and countries. GIS data is much more advanced, recording changes in elevation, air patterns, pollution and water levels. Mathematical skills are also necessary, as they help DBAs draw correlative relationships between major GIS data sets. GIS DBAs should be aware of how different environmental events impact others and what consequences they may carry to data that's being sorted by them.
Job Overview
GIS DBAs will perform a variety of responsibilities over the course of their careers. Leveraging their technical skill sets, GIS DBAs will support the planning and development of GIS databases, generate reports based on that data and drive the creation of new research methods and computational activities. They're also responsible for data entry, modification and maintenance. Data integrity becomes very important over time, as historical data gets called upon in future research projects as reference points.
Technical Proficiencies
DBAs who work in GIS capacities need to have a unique skill set that combines traditional computer database skills with knowledge of GIS data systems. Commonly required skills include SQL Server, MySQL, ArcGIS Server, .NET, ArcGIS desktop, Visual Basic, SharePoint, and ArcPAD. The Arcline software products are designed specifically for GIS data management, making them an essential item that should be in any GIS DBA's toolbox. Professionals in this field should also know how to extrapolate data from all of these different sources and develop models, theories and relational databases.
Report Generation
Generating reports is one of the foremost responsibilities of GIS DBAs. While scientists may be the geographic subject matter experts, they can't do much without access to the geographic data. Furthermore, with the data in its raw form, it will take them much longer to model and analyze it. This is where the core function of a GIS DBA enters into play. These professionals help query specific data that researchers need access to, then reformat the data into more palatable forms, such as charts and visual graphs.

Can I Work on WordPress Offline?In Feburary 2016 11,

In Feburary 2016 11,
Users may want to work with WordPress offline for several reasons. One use for offline WordPress is as a test environment. An offline, local installation of WordPress offers a safe, easily restored environment to test changes to the WordPress installation, such as code implementation or layout testing.
Local Server
WordPress can run on any computer that supports PHP scripting language and MySQL databases. Windows, Mac and Linux machines can all be configured to support this environment. Once enabled, users can install the WordPress web application and then access this installation from their local machine. Local server installations work exactly like online WordPress installations, except instead of typing an Internet URL to access the WordPress installation, users enter their local hostname or http://127.0.0.1 address to point to the installation.
Desktop Blogging Clients
Desktop blogging clients allow users to draft posts offline, though most other administrative functions must still be done via an online connection to the WordPress installation. WordPress-compatible desktop blogging clients include Windows Live Writer, BlogDesk and Qumana. Features vary between desktop clients, but most include post creation, categorization and tagging. More advanced desktop clients may allow a user to manage other aspects of her blog, such as creating local backups.
Maintenance Mode
Users who want to take their WordPress site offline but still work with the backend have the option of installing a plugin that will put the WordPress site in maintenance mode. Maintenance mode will close the site to incoming user connections but allow administrators and other authorized users access to the live site. Though not truly working offline, enabling maintenance mode is a viable alternative for users who only need to take WordPress offline temporarily.

Pitfalls in Relational Database DesignIn Feburary 2016 08,

In Feburary 2016 08,
Choosing names is an aspect of database design that is often neglected but can have a considerable impact on usability and future development. To avoid this, both table and column names should be chosen to be meaningful and to conform to the established conventions, ensuring that consistency is maintained throughout a system. A number of conventions can be used in relational database names, including the following two examples for a record storing a client name: 'client_name' and 'clientName.'
Lack of Documentation
Creating documentation for a relational database can be a vital step in safeguarding future development. There are different levels of documentation that can be created for databases, and some database management systems are able to generate the documentation automatically. For projects where formal documentation is not considered necessary, simply including comments within the SQL code can be helpful.
Failure to Normalize
Normalization is a technique for analyzing, and improving on, an initial database design. A variety of techniques are involved, including identifying features of a database design that may compromise data integrity, for example items of data that are stored in more than one place. Normalization identifies anomalies in a database design, and can preempt design features that will cause problems when data is queried, inserted or updated.
Lack of Testing
Failure to test a database design with a sample of real, or realistic, data can cause serious problems in a database system. Generally, relational database design is started from an abstract level, using modeling techniques to arrive at a design. The drawback to this process is that the design sometimes will not relate accurately to the actual data, which is why testing is so important.
Failure to Exploit SQL Facilities
SQL has many capabilities that can improve the usability and success of a database system. Facilities such as stored procedures and integrity checks are often not used in cases where they could greatly enhance the stability of a system. Developers often choose not to carry out these processes during the design stages of a project as they are not a necessity, but they can help to avoid problems at a later stage.
