Database manager job description

The nitty gritty
Your scheduled hours should be 9am to 5pm Monday to Friday but it's likely that you'll be on-call in case of any technical problems outside of these hours.
If you find a job in-house you'll be based out of your office. If you work for a company that specialises in building databases for clients then much of your time will be spent at the client's office.
There are part-time jobs out there if you're looking for job flexibility. You may also be able to work from home if you can get online.
If you enjoy the technical side of the job you should look for opportunities to become a technical architect or an analyst.
If you enjoy the people aspects of your role you could move more into the customer relationship management side of things or into business analysis.

Money, money, money
In terms of annual income, the average database manager is on around RM38,000 to RM39,000.

The good points...
As you can see, the salary isn’t too bad, which with experience can jump to around RM42,000. 

...and the bad
With big maintenance or development projects there may be some times when you need to work in the evening or weekends as you'll need to carry out the work with minimum disruption.
Is there study involved?
You'll usually need an IT related degree but if you've worked your way up and show you've got all the right experience then the job could be yours.
It's a specialist arm of computing so up to date, professional qualifications in database packages will be important for getting started.
You should demonstrate some specific experience in managing a database, maybe from a previous role as a database administrator.
Ask your employer if they will send you on any soft skills courses. It's always beneficial to keep your communications, management and presentation skills up to date

History

In earlier computing models, e.g. in client-server, the load for the application was shared between code on the server and code installed on each client locally. In other words, an application had its own client program which served as its user interface and had to be separately installed on each user's personal computer. An upgrade to the server-side code of the application would typically also require an upgrade to the client-side code installed on each user workstation, adding to the support cost and decreasing productivity. In addition, both the client and server components of the application were usually tightly bound to a particular computer architecture and operating system and porting them to others was often prohibitively expensive for all but the largest applications.

In contrast, web applications use web documents written in a standard format such as HTML and JavaScript, which are supported by a variety of web browsers. Web applications can be considered as a specific variant of client-server software where the client software is downloaded to the client machine when visiting the relevant web page, using standard procedures such as HTTP. Client web software updates may happen each time the web page is visited. During the session, the web browser interprets and displays the pages, and acts as the universal client for any web application.

In the early days of the Web each individual web page was delivered to the client as a static document, but the sequence of pages could still provide an interactive experience, as user input was returned through web form elements embedded in the page markup. However, every significant change to the web page required a round trip back to the server to refresh the entire page.

In 1995 Netscape introduced a client-side scripting language called JavaScript allowing programmers to add some dynamic elements to the user interface that ran on the client side. So instead of sending data to the server in order to generate an entire web page, the embedded scripts of the downloaded page can perform various tasks such as input validation or showing/hiding parts of the page.

In 1996, Macromedia introduced Flash, a vector animation player that could be added to browsers as a plug-in to embed animations on the web pages. It allowed the use of a scripting language to program interactions on the client side with no need to communicate with the server.

In 1999, the "web application" concept was introduced in the Java language in the Servlet Specification version 2.2. [2.1?].[4][5] At that time both JavaScript and XML had already been developed, but Ajax had still not yet been coined and the XMLHttpRequest object had only been recently introduced on Internet Explorer 5 as an ActiveX object.[6]

In 2005, the term Ajax was coined, and applications like Gmail started to make their client sides more and more interactive. A web page script is able to contact the server for storing/retrieving data without downloading an entire web page.

In 2011, HTML5 was finalized, which provides graphic and multimedia capabilities without the need of client side plug-ins. HTML5 also enriched the semantic content of documents. The APIs and document object model (DOM) are no longer afterthoughts, but are fundamental parts of the HTML5 specification. WebGL API paved the way for advanced 3D graphics based on HTML5 canvas and JavaScript language. These have significant importance in creating truly platform and browser independent rich web applications.

Benefits

A web application relieves the developer of the responsibility of building a client for a specific type of computer or a specific operating system. Since the client runs in a web browser, the user could be using an IBM-compatible or a Mac. They can be running Windows XP or Windows Vista. They can even be using Internet Explorer or Firefox, though some applications require a specific web browser.

Web applications commonly use a combination of server-side script (ASP, PHP, etc) and client-side script (HTML, Javascript, etc.) to develop the application. The client-side script deals with the presentation of the information while the server-side script deals with all the hard stuff like storing and retrieving the information.

Techopedia explains Web-Based Application

There is a lot of confusion created by the use of terms like Web-based, Internet-based and cloud-based when referring to applications. Web-based applications actually encompass all the applications that communicate with the user via HTTP. This includes light applications like Flash games, online calculators, calendars, and so on, as well as more intensive applications that use HTTP.

Definition - What does Web-Based Application mean?

A Web-based application refers to any program that is accessed over a network connection using HTTP, rather than existing within a device’s memory. Web-based applications often run inside a Web browser. However, Web-based applications also may be client-based, where a small part of the program is downloaded to a user’s desktop, but processing is done over the Internet on an external server.

Web-based applications are also known as Web apps.
