Oracle, MySQL, Cassandra, Hadoop Database Training in San Francisco, California

Learning SQL development can seem like an overwhelming task at first. However, mastering just a few key points will help ease your way through 80 percent of the day-to-day challenges when writing stored procedures and solving common problems. Here are three important SQL development factors to keep in mind:

Outer Joins
One of the most crucial things to understand in SQL server are joins. Joins are a way to retrieve data from two or more tables based on logical relationships between them. Joins dictate how Microsoft SQL Server ought to use data from one table to select the rows in another table.

In my experience inner joins are intuitive while outer joins can present additional hours of grief by overlooking associations in the other table(s). The outer join is the key to answering questions about what the database does not have. For example, if you need to make a query to display all the students who are without report-cards, you’ll need a left join to get all students coupled with a “where clause” to return the ones who have nulls for their report card table columns in the results.

Many talented Java script programmers have muddled through the SQL Server by deficient coding around the inner join. As a result, their queries can take five hours to run, whereas, properly written left joins, can take only two seconds to run.

Aggregation
Grouping results comes up in SQL a lot more than you might think. Knowing how to write a query when answering questions such as, “What’s the average grade for each teacher’s student list?” is invaluable. This kind of question cannot be answered with a single table or solely by joins. You’ll often find you need to use joins in conjunction with group by statements. Always write the raw query first and then look at the results. Next, you have to figure out the best way to group them, rewrite your select clause and add a group by clause in the end.

Digging Through Data
I find this is the most lacking skill in many programmers. In fact, many otherwise-talented programmers holding Master’s Degrees fail to get jobs because they couldn’t analyze rows of data objectively during interviews. It’s just something that’s not taught but is crucial to get under you belt. Why? Eventually, some query is not going to perform as you may expect. And, the only way to find discrepancies is to look at rows of data, identify what join isn’t finding a match or where bad data is throwing things into chaos. Get familiar with how joins actually work, even if you have to manually walk through the logic of a large stored procedure’s tree of joins. It’s boring and time-consuming but absolutely necessary.

Take the time to master the core skills that will make you a successful SQL Programmer and avoid queries that run for five hours!

Facebook Releases C++Software Modules, May Lead To More Open Source

[Jun, 13, 2012] |

Facebook has recently released a collection of C++ software modules that it uses to run the popular website. With Facebook releasing Folly (the name it designated for the collection), more of the internal programs could become open source since they need different parts of the collection.

Jordan DeLong, a Facebook software engineer, said one concerning holdup to releasing additional work is that any open source project had to cut away from the dependencies on non-released internal collection code.

What is the most pressing problem in Project Management for a SoftwareProject Manager?

[May, 02, 2014] |
Tags:

A project manager acts as the primary link between business and technical teams. A project manager is responsible for maintaining the project schedule, developing project estimates, working with external teams and tracking project issues. The project manager belongs to either the technical team or the project management office (PMO). The project manager works with business teams, technical teams, business counterparts, testing resources, vendors and infrastructure teams.

A project manager is often challenged with diagonally opposite views from the business side and technical side. A project manager’s success depends on balancing the needs and emotions of both sides.

Understanding the Requirements
A project manager must familiarize with the project’s requirements as defined by the business or product managers. This will help you understand the business vision behind the project. You will need this knowledge while negotiating with the technical teams.

Understanding the Technical Landscape
A project manager must also understand the technical systems, resource skills and infrastructure capabilities available for the project. Business teams come up with expectations that are sometimes beyond the capabilities of the technology team. It is the responsibility of the project manager to understand the technical capabilities available to the project.

Walkthrough of Business Requirements
This is a critical step in the project delivery process. The project manager must invite members from the business team, technical team, testing team, infrastructure team and vendors. The project manager must encourage the various stakeholders to ask questions about the requirements. Any prototypes available must be demonstrated in this meeting. The project manager must find answers to all questions resulting from the requirements walkthrough. The project manager must get the final version of the requirements approved by all stakeholders.

Managing Conflicts in Timelines and Budgets
All project managers will face the conflicts arising from shortened timelines and limited budgets. Business teams typically demand many features that are nearly impossible to deliver within short timeframes. The project manager must work with business and technical teams to prioritize the requirements. If the project is executed in a product development organization, then the project manager could utilize agile methodologies to deliver projects incrementally. In this case, the project manager may be required to act as a scrum master to facilitate scrum meetings between various stakeholders.

The Art of Saying “No”
As a project manager, you may be forced to say “no” to demands from both business and technology teams. However, it is important to create a win-win situation for all parties when you are faced with conflicting demands. You can work with the stakeholders individually before bringing all parties together. Most stakeholders prefer to work together. The success of a project manager depends on how effectively he or she can bring out the best in everyone, driving everyone towards a common goal.

Finally, the job of a project manager is not to satisfy the demands from all corners. The project manager must identify the essential deliverables that will meet the business needs, with a solid understanding of what is possible within the limits of technology.

IT Job Roles and Responsibilities Explained

[Apr, 30, 2019] |
Tags:

Let's face it, IT roles have evolved and are no longer meant for the IT department alone. Most departments tend to have a technical person that can help make sense of data. These days, businesses encourage data democratization, meaning that everyone in the business is responsible for the information that the organization receives. Departments no longer have to wait for data to pass through IT before they receive it. The departments get information as it comes. Then, they make decisions based on that data.

IT Job Roles and Responsibilities

1. Project Manager

A project manager, in this case, is someone that plays a managerial role in a company’s project. In fact, this is one of the most important IT job roles. The manager is responsible for his or her team. He or she makes sure that deadlines are met, and the project proceeds as planned. It mainly includes planning, design, initiation, monitoring, execution, and control.

2. IT Director

In most cases, the term director is associated with big positions in a company, and is often associated with a board role. As one of the top IT job roles, the IT director is responsible for planning, managing and executing the core-infrastructure of a company. The primary role of the IT director is to oversee all the technology operations within the firm. The director then evaluates what his or her team does to make sure that the activities are in line with firm’s main objectives. On top of that, the IT director makes sure that all departments have their technology needs met by his or her team.

3. IT Manager

The rank of an IT manager is definitely lower than that of a director, however, the role is still very crucial for any IT department. Every IT department has staff members that are meant to deliver results at the end of the day. The IT manager supervises most of the workers in the IT department. He or she is in charge of motivating them and making sure that they do what they are supposed to do. The IT manager’s roles include monitoring, planning, coaching, disciplining employees, and counseling.

4. Software Engineer

This position can also be referred to as a software architect, system engineer or application programmer. The main work typically involves creating and programming system-level software such as database systems, operating systems, and embedded systems. Their primary role is to ensure that they understand how both software and hardware work and to use them appropriately. However, the responsibilities don’t stop there. The software engineer is also required to interact with both colleagues and clients to explain which system or solution is going to be more suitable for use.

5. Systems Analyst

A systems analyst can also be called a solutions specialist, product specialist or a systems engineer. Their primary work mainly involves identifying, analyzing, and coming up with new information systems that will provide a viable solution. This is mostly done as a response to the requests of customers or just for the business. They also have to make sure that they determine the costs and total time required to bring the information systems into effect.

6. Helpdesk Support

There are times when your team could encounter system problems. Perhaps, a piece of hardware or software has malfunctioned. You need helpdesk support to deal with such issues. This is a professional that knows about common computer problems. Without them, business operations could stall because an employee can be stranded, and there’s no one to help.

7. Network Designer

As much as helpdesk support can solve most IT problems, there are other issues that they can’t solve. You may experience system shutdowns or slow internet. In that case, you need an expert in maintaining communication systems. These professionals will also be responsible for setting up cyber security systems for the organization.

IT involves many job roles and responsibilities that all work hand-in-hand to deliver results. As you begin your business, you should know about these roles so that you can know which ones are going to be the most suitable for your firm.
