  • Please recommend the best tools to build a test plan management tool

    - by fzkl
    I have mostly worked on hardware testing in my professional career and would like to get onto the software development side. I thought working on a practically usable project will help motivate me and help acquire some skills. I have decided to build a test plan management tool for the QA team I work in (We use excel sheets!). The test plan management tool should be browser based and should support this: There would be many test plans, each test plan having test sets, test sets having test cases and test cases having instructions, attachments and Pass/fail status marking and bug info in case of failure. It should also have an export to excel option. I have a visual picture of the tool I am looking to build but I don't have enough experience to figure our where to start. My current programming skills are limited to C and shell programming and I want to pick up python. What tools (programming language, database and anything else?) would you recommend for me to get this done? Also what are the key concepts in the recommended programming language that I should focus on to build a browser based tool like this?

  • What is a Relational Database Management System (RDBMS)?

    A Relational Database Management System (RDBMS)  can also be called a traditional database that uses a Structured Query Language (SQL) to provide access to stored data while insuring the integrity of the data. The data is stored in a collection of tables that is defined by relationships between data items. In addition, data permitted to be joined in new relationships. Traditional databases primarily process data through transactions called transaction processing. Transaction processing is the methodology of grouping related business operations based predefined business events. An example of this can be seen when a person attempts to purchase an item from an online e-tailor. The business must execute specific operations for a related  business event. In this case, a business must store the following information: Customer Info, Order Info, Order Item Info, Customer Payment Data, Payment Results, and Current Order Status. Example: Pseudo SQL Operations needed for processing an online e-tailor sale. Insert Customer into Customers Insert New Order into Orders Insert Each New Order Item into OrderItems Insert Customer Payment Info into PaymentInfo Insert Payment Processing Result into PaymentDetails Update Customer for Current Order Status Common Relational Database Management System Microsoft SQL Server Microsoft Access Oracle MySQL DB2 It is important to note that no current RDBMS has fully implemented all of the Relational Principles. Common RDBMS Traits Volatile Data Supports Transaction Processing Optimized for Updates and Simple Queries

  • Intermittent 403 errors when using allow to limit access to url with both explicit IP and SetEnvIf

    - by rbieber
    We are running Apache 2.2.22 on a Solaris 10 environment. We have a specific URL that we want to limit access to by IP. We recently implemented a CDN and now have the added complexity that the IP's that a request are shown to be coming from are actually the CDN servers and not the ultimate end user. In the case that we need to back the CDN out, we want to handle the case where either the CDN is forwarding the request, or the ultimate client is sending the request directly. The CDN sends the end user IP address in an HTTP header (for this scenario that header is called "User-IP"). Here is the configuration that we have put in place: SetEnvIf User-IP (\d+\.\d+\.\d+\.\d+) REAL_USER_IP=$1 SetEnvIf REAL_USER_IP "(10\.1\.2\.3|192\.168\..+)" access_allowed=1 <Location /uri/> Order deny,allow Allow from 10.1.2.3 192.168. allow from env=access_allowed Deny from all </Location> This seems to work fine for a time, however at some point the web server starts serving 403 errors to the end user - so for some reason it is restricting access. The odd thing is that a bounce of the web server seems to resolve the issue, but only for a time - then the behavior comes back. It might be worthwhile to note as well that this URL is delegated to a JBoss server via mod_jk. The denial of access is, however; confirmed to be at the Apache layer and the issue only seems to happen after the server has been running for some time.

  • In Social Relationship Management, the Spirit is Willing, but Execution is Weak

    - by Mike Stiles
    In our final talk in this series with Aberdeen’s Trip Kucera, we wanted to find out if enterprise organizations are actually doing anything about what they’re learning around the importance of communicating via social and using social listening for a deeper understanding of customers and prospects. We found out that if your brand is lagging behind, you’re not alone. Spotlight: How was Aberdeen able to find out if companies are putting their money where their mouth is when it comes to implementing social across the enterprise? Trip: One way to think about the relative challenges a business has in a given area is to look at the gap between “say” and “do.” The first of those words reveals the brand’s priorities, while the second reveals their ability to execute on those priorities. In Aberdeen’s research, we capture this by asking firms to rank the value of a set of activities from one on the low end to five on the high end. We then ask them to rank their ability to execute those same activities, again on a one to five, not effective to highly effective scale. Spotlight: And once you get their self-assessments, what is it you’re looking for? Trip: There are two things we’re looking for in this analysis. The first is we want to be able to identify the widest gaps between perception of value and execution. This suggests impediments to adoption or simply a high level of challenge, be it technical or otherwise. It may also suggest areas where we can expect future investment and innovation. Spotlight: So the biggest potential pain points surface, places where they know something is critical but also know they aren’t doing much about it. What’s the second thing you look for? Trip: The second thing we want to do is look at specific areas in which high-performing companies, the Leaders, are out-executing the Followers. This points to the business impact of these activities since Leaders are defined by a set of business performance metrics. Put another way, we’re correlating adoption of specific business competencies with performance, looking for what high-performers do differently. Spotlight: Ah ha, that tells us what steps the winners are taking that are making them winners. So what did you find out? Trip: Generally speaking, we see something of a glass curtain when it comes to the social relationship management execution gap. There isn’t a single social media activity in which more than 50% of respondents indicated effectiveness, which would be a 4 or 5 on that 1-5 scale. This despite the fact that 70% of firms indicate that generating positive social media mentions is valuable or very valuable, a 4 or 5 on our 1-5 scale. Spotlight: Well at least they get points for being honest. The verdict they’re giving themselves is that they just aren’t cutting it in these highly critical social development areas. Trip: And the widest gap is around directly engaging with customers and/or prospects on social networks, which 69% of firms rated as valuable but only 34% of companies say they are executing well. Perhaps even more interesting is that these two are interdependent since you’re most likely to generate goodwill on social through happy, engaged customers. This data also suggests that social is largely being used as a broadcast channel rather than for one-to-one engagement. As we’ve discussed previously, social is an inherently personal media. Spotlight: And if they’re still using it as a broadcast channel, that shows they still fail to understand the root of social and see it as just another outlet for their ads and push-messaging. That’s depressing. Trip: A second way to evaluate this data is by using Aberdeen’s performance benchmarking. The story is both a bit different, but consistent in its own way. The first thing we notice is that Leaders are more effective in their execution of several key social relationship management capabilities, namely generating positive mentions and engaging with “influencers” and customers. Based on the fact that Aberdeen uses a broad set of performance metrics to rank the respondents as either “Leaders” (top 35% in weighted performance) or “Followers” (bottom 65% in weighted performance), from website conversion to annual revenue growth, we can then correlated high social effectiveness with company performance. We can also connect the specific social capabilities used by Leaders with effectiveness. We spoke about a few of those key capabilities last time and also discuss them in a new report: Social Powers Activate: Engineering Social Engagement to Win the Hidden Sales Cycle. Spotlight: What all that tells me is there are rewards for making the effort and getting it right. That’s how you become a Leader. Trip: But there’s another part of the story, which is that overall effectiveness, even among Leaders, is muted. There’s just one activity in which more than a majority of Leaders cite high effectiveness, effectiveness being the generation of positive buzz. While 80% of Leaders indicate “directly engaging with customers” through social media channels is valuable, the highest rated activity among Leaders, only 42% say they’re effective. This gap even among Leaders shows the challenges still involved in effective social relationship management. @mikestilesPhoto: stock.xchng

  • How do Oracle Forms compare to Microsoft Access as a "front-end"?

    - by webworm
    I recently started a project where I was set to build an ADP based application in Access 2003. The font end GUI was going to be in Access while all the data resided in MS SQL Server. I say "was", because the powers that be have decided that Oracle Forms might be a better choice than Access and SQL Server. The place where I am doing this work is an Oracle shop where they use Oracle 10g. They also use Oracle Forms quite a bit internally. As for me I am always up for learning anything new. I have always been a rather "eclectic" developer (I work with .NET WinForms, ASP.NET, Java, C#, Python, and Access) so I would not mind moving to Oracle Forms as long as it could do the same things as MS Access (hopefully even more as VBA is rather limited). So my question is this. How does Oracle Forms (10g) compare to MS Access for developing a GUI application? Access uses VBA for it's language, what does Oracle Forms use? I know the Forms app is a Java applet. Does that means you can write Oracle Forms using Java?

  • What is a good software development plan?

    - by Totophil
    Whilst browsing through answers on SO I came across something that is, in my view, one of the more frequent software development management misconceptions: "[software development] plan is a reasonably detailed description of all the activities you need to undertake". Hence the question: what is good software development plan? Can it be boiled down just to a work breakdown structure; is WBS the single most important thing for a software development plan anyway?

  • Authoritative sources about Database vs. Flatfile decision

    - by FastAl
    <tldr>looking for a reference to a book or other undeniably authoritative source that gives reasons when you should choose a database vs. when you should choose other storage methods. I have provided an un-authoritative list of reasons about 2/3 of the way down this post.</tldr> I have a situation at my company where a database is being used where it would be better to use another solution (in this case, an auto-generated piece of source code that contains a static lookup table, searched by binary sort). Normally, a database would be an OK solution even though the problem does not require a database, e.g, none of the elements of ACID are needed, as it is read-only data, updated about every 3-5 years (also requiring other sourcecode changes), and fits in memory, and can be keyed into via binary search (a tad faster than db, but speed is not an issue). The problem is that this code runs on our enterprise server, but is shared with several PC platforms (some disconnected, some use a central DB, etc.), and parts of it are managed by multiple programming units, parts by the DBAs, parts even by mathematicians in another department, etc. These hit their own platform’s version of their databases (containing their own copy of the static data). What happens is that every implementation, every little change, something different goes wrong. There are many other issues as well. I can’t even use a flatfile, because one mode of running on our enterprise server does not have permission to read files (only databases, and of course, its own literal storage, e.g., in-source table). Of course, other parts of the system use databases in proper, less obscure manners; there is no problem with those parts. So why don’t we just change it? I don’t have administrative ability to force a change. But I’m affected because sometimes I have to help fix the problems, but mostly because it causes outages and tons of extra IT time by other programmers and d*mmit that makes me mad! The reason neither management, nor the designers of the system, can see the problem is that they propose a solution that won’t work: increase communication; implement more safeguards and standards; etc. But every time, in a different part of the already-pared-down but still multi-step processes, a few different diligent, hard-working, top performing IT personnel make a unique subtle error that causes it to fail, sometimes after the last round of testing! And in general these are not single-person failures, but understandable miscommunications. And communication at our company is actually better than most. People just don't think that's the case because they haven't dug into the matter. However, I have it on very good word from somebody with extensive formal study of sociology and psychology that the relatively small amount of less-than-proper database usage in this gigantic cross-platform multi-source, multi-language project is bureaucratically un-maintainable. Impossible. No chance. At least with Human Beings in the loop, and it can’t be automated. In addition, the management and developers who could change this, though intelligent and capable, don’t understand the rigidity of this ‘how humans are’ issue, and are not convincible on the matter. The reason putting the static data in sourcecode will solve the problem is, although the solution is less sexy than a database, it would function with no technical drawbacks; and since the sharing of sourcecode already works very well, you basically erase any database-related effort from this section of the project, along with all the drawbacks of it that are causing problems. OK, that’s the background, for the curious. I won’t be able to convince management that this is an unfixable sociological problem, and that the real solution is coding around these limits of human nature, just as you would code around a bug in a 3rd party component that you can’t change. So what I have to do is exploit the unsuitableness of the database solution, and not do it using logic, but rather authority. I am aware of many reasons, and posts on this site giving reasons for one over the other; I’m not looking for lists of reasons like these (although you can add a comment if I've miss a doozy): WHY USE A DATABASE? instead of flatfile/other DB vs. file: if you need...

I’m looking for a paper book I can buy, or a reputable website with whitepapers about the issue (e.g., Microsoft, IBM), not counting the user-generated content on those sites. This will have a greater change to elicit a change that I’m looking for: less wasted programmer time, and more reliable programs. Thanks very much for your help. You win a prize for reading such a large post!

  • what's the key different between data management and data governance?

    - by Sid Xing
    i just read some articles about these two theories, and i thought they have the similar goal, but DG is more about process management by follow some best practice. So my 1st question is about the difference between DG & DM. I'm confused. There're so many concepts around data management. Data quality, data security, data governance, data profiling, data integration, master data management, metadata management.... It seems like neither of them is EXACTLY separated, they're together. My 2nd question, or ask for your suggestion to help me better understand the relation between these concepts. Appreciate your help.

  • What is New in ASP.NET 4.0 Code Access Security

    - by HosamKamel
    ASP.NET Code Access Security (CAS) is a feature that helps protect server applications on hosting multiple Web sites, ASP.NET lets you assign a configurable trust level that corresponds to a predefined set of permissions. ASP.NET has predefined ASP.NET Trust Levels and Policy Files that you can assign to applications, you also can assign custom trust level and policy files. Most web hosting companies run ASP.NET applications in Medium Trust to prevent that one website affect or harm another site etc. As .NET Framework's Code Access Security model has evolved, ASP.NET 4.0 Code Access Security also has introduced several changes and improvements.   A Full post addresses the new changes in ASP.NET 4.0 is published at Asp.Net QA Team Here http://weblogs.asp.net/asptest/archive/2010/04/23/what-is-new-in-asp-net-4-0-code-access-security.aspx

  • SQL SERVER – Remove Debug Button in SSMS – SQL in Sixty Seconds #020 – Video

    - by pinaldave
    SQL in Sixty Seconds is indeed tremendous fun to do. Every week, we try to come up with some new learning which we can share in Sixty Seconds. In this busy world, we all have sixty seconds to learn something new – no matter how much busy we are. In this episode of the series, we talk about another interesting feature of SQL Server Management Studio. In SQL Server Management Studio (SSMS) we have two button side by side. 1) Execute (!) and 2) Debug (>). It is quite confusing to a few developers. The debug button which looks like a play button encourages developers to click on the same thinking it will execute the code. Also developer with a Visual Studio background often click it because of their habit. However, Debug button is not the same as Execute button. In most of the cases developers want to click on Execute to run the query but by mistake they click on Debug and it wastes their valuable time. It is very easy to fix this. If developers are not frequently using a debug feature in SQL Server they should hide it from the toolbar itself. This will reduce the chances to incorrectly click on the debug button greatly as well save lots of time for developer as invoking debug processes and turning it off takes a few extra moments. In this Sixty second video we will discuss how one can hide the debug button and avoid confusion regarding execution button. I personally use function key F5 to execute the T-SQL code so I do not face this problem that often.

  • How to Access a Windows Desktop From Your Tablet or Phone

    - by Chris Hoffman
    iPads and Android tablets can’t run Windows apps locally, but they can access a Windows desktops remotely — even with a physical keyboard. In a pinch, the same tricks can be used to access a Windows desktop from a smartphone. Microsoft recently launched their own official Remote Desktop app for iOS and Android devices. Microsoft’s official apps are primarily useful for businesses — if you’re a typical home user, you’ll want to use a different remote desktop solution. Microsoft’s Remote Desktop App Microsoft now offers official Remote Desktop apps for iPad and iPhone as well as Android tablets and smartphones. The apps use Microsoft’s RDP protocol to connect to remote Windows systems. They’re essentially just new clients for the Remote Desktop feature that has been included in Windows for more than a decade. There are big problems with these apps if you’re an average home user. Microsoft’s Remote Desktop server is not available on standard or Home versions of Windows, only Professional and Enterprise editions. If you do have the appropriate edition of Windows, you’ll have to set up port-forwarding and a dynamic DNS service if you want to access your Windows desktop from outside your local network. You could also set up a VPN — either way you’ll need to do some footwork. This app is a gift to businesses who are already using Remote Desktop and enthusiasts who have the more expensive versions of Windows and don’t mind the configuration process. To set this up, follow our guide to setting up Remote Desktop for Internet access and connect using the Remote Desktop app instead of traditional Remote Desktop clients. TeamViewer If you have the standard edition of Windows or you just don’t want to mess around with port-forwarding and dynamic DNS configuration, you’ll want to skip Remote Desktop and use something else. We like TeamViewer for this. Just as it’s a great way to remotely troubleshoot your relatives’ computers, it’s also a great way to remotely access your own computer. It doesn’t have the same limitations Microsoft’s Remote Desktop system has — it’s completely free for personal use, runs on any edition of Windows, and is easy to set up. There’s no messing around with port-forwarding or dynamic DNS configuration. To get started, just download and run the TeamViewer program on your computer. You can get started with it immediately, but you’ll want to set up unattended access to connect remotely without using the codes displayed on your screen. To connect, just install the TeamViewer mobile app and log in with the details the TeamViewer window displays. TeamViewer also offers software that runs on Mac and Linux, so you can remote-control other types of computers from your tablet. Other Options Microsoft’s Remote Desktop app and TeamViewer aren’t the only options, of course. There are a variety of different apps and services built for this. Splashtop is another fairly popular remote desktop solution that some people report as being faster. Unfortunately, it’s not entirely free — the iPad and iPhone app costs $20 at regular price. To use it over the Internet, you’ll have to purchase an additional “Anywhere Access Pack.” If you’re frustrated with TeamViewer’s speed and you don’t mind spending money, you may want to try Splashtop instead. As always, you could use any VNC server along with a VNC client app. VNC is the do-it-yourself solution — it’s an open protocol. Unlike Microsoft’s RDP protocol, you can install a VNC server of your own, configure it how you like, and use any mobile VNC client app. This is more flexible because you can install a VNC server on any edition of Windows or even non-Windows operating systems, but it otherwise has all the same issues — you have to worry about port-forwarding, setting up dynamic DNS, and securing your VNC server. Keep an eye on Chrome Remote Desktop. Chrome already offers a built-in remote desktop feature that allows you to remotely control your PC from another Windows, Mac, Linux, or Chrome OS device. Google is rumored to be building an Android app for Chrome Remote Desktop, which would allow you to easily access a computer running Chrome from Android tablets. Google’s solution is much more user-friendly for average people than Microsoft’s Remote Desktop solution, which is clearly geared towards businesses. Chrome Remote Desktop just requires signing in with a Google account. Remote desktop solutions like Microsoft’s Remote Desktop app and TeamViewer are also available for Windows tablets. On Windows RT devices like the Surface RT and Surface 2, they allow you to use the full Windows desktop that’s unavailable on your tablet.
