SQL Server comes with several tools named services. The SQL Server Reporting Services (SSRS) is one such tool that lets you compose reports exactly the way you need them. The suite of services provided by Microsoft also includes an Analysis services module and integration services module. Creation and management of a wide variety of these reports is made possible through this server based reporting service or the SSRS. The types of reports that can be created include the basic one that contain data tables and associated charts. Complex data visualizations are made possible by the SQL server reporting services. The complex reports may contain charts, maps and sparklines. Sparklines make more sophisticated visualizations possible and they help add additional illustrative small charts to data in a chart already. This reporting service tool can handle these easily. All these reports can be generated in different formats. The data used for the reports could not only e SQL Server data but can also come from other RDMSs. SQL server analysis services can be a source as could be Parallel data warehouse or even Teradata. The reporting service can handle XML based data sources too.
The reports generated by the SQL server reporting services can be included in the applications you develop. These could as easily be viewed on the report manager or the report services website. The required reports in reporting services can be generated as required basis. These could be scheduled as subscriptions too. This component of SSRS can be arranged to install on SharePoint.
Originally SQL Server Reporting Services (SSRS) used to be shipped as an adjunct to the main SQL Server product. It was first released more than 10 years ago in 2003. From the SQL Server release 2005, the services have been completely integrated. The SSRS was enhanced significantly in the 2008 and 2008 R2 versions. These new set of features enhancements include enhanced charts, data regions, a new gage feature, formatting of text an introduction of a Tablix feature. This lets a report area to be converted to matrix and the other way round. A complete overhaul of the report designer was done at this release. This redesign introduced a grouping pane in the interface. Basic features of this reporting services have not changed since this 2008 R2 release.
A Power View feature was added, however, with the SQL server reporting services release 2012. Power View provides a new way of creating reports that business users need. A SSRS installation needs to be associated with a database instance, of course. A ReportServer and a ReportServerTempdb exist in such an instance. ReportServer holds quite a few details about reports created. These include definitions of the report, its configuration, security and history, etc. On the other hand ReportServerTempdb provides a workspace for building of reports. A Report Server Web Service will need to be hosted. End users can publish their own reports when they have permissions. The sequence of events in publishing a report starts with a http request to the web server. The reporting services server retrieves metadata related to the report and requests data from the data source and returns a complete report when data is available to it.
Microsoft’s RDBMS product for desktops and enterprise is the SQL Server and SQL Server 2012 is the version released to the market in 2012. The SQL Server 2012 evolved from the 2005 version. The SQL server code started out to be jointly owned by Microsoft and two other companies named Ashton Tate and Sybase. It was released as the desktop product on PS/2 with OS/2 environment back in 1989. By the time several upgrades were released to arrive at the sql server version 2005, Microsoft has own version of the code contributed by Ashton Tate by this time. The 2012 version evolved through 2008, 2008 R2 versions to become the SQL Server 2012.
The SQL Server 2012 grew into the SQL Server 2014 version and the latest product from Microsoft stable is the community technology preview 2016 that has just been released recently. The sql server 2012 adds two major trends to the feature list that was available with the previous 2008 R2 version.
With the SQL Server 2012, Microsoft decided to support only ODBC (open database connectivity). Even the interconnectivity between MS document types supported through OLE was to be dropped. The general release of the SQL Server 2012 came in Mar, 2012 followed by release of Service pack 1 in Nov 2012 and the pack2, in Nov, 2014. The added features include a PowerView. When creating business intelligence reports, you can mash up various data sets in SQL Server 2012 through this feature. Operationally, the AlwaysOn feature adds handling of database failures easier. Multiple copies created by the system in SQL Server 2012 helps make disaster recover quite straightforward. There is even a stripped down version which is not as resources hungry as the full version of the SQL Server 2012 but can let you carry out the most important operations. Programming features enhanced in the SQL Server 2012 include a ColumnStore indexes feature. These are read-only indexes that help optimizing processing queries on large data warehouses. Testing of the SQL Server 2012 procedures and queries can be played out (tried out) on a non-production server without risking crashes affecting your production operations. Operationally, an audit trail is a very important tool for systematic management of the database operations but a security safeguard against malicious activities, if any.
By this point in the development of the SQL Server product, SQL Server 2012 has evolved into an enterprise level DBMS with the ability to handle large volume of enterprise level data, supported by the administrative, program development and security features required for efficient operations. The next upgrade to SQL Server 2012 came in 2014.

SQL Update is a command or updating a data record. SQL Update query is part of the SQL standard that is implemented by all product vendors. Thus, the concept applies uniformly across all RDBMS products. Typically, in an RDBMS based database, data is organized as rows and columns. Each row of data has fields in columns that are related. One row of data is called a record. SQL Update is a means of updating a field within a record in the database. The syntax of SQL Update command provides for specifying the particular piece of data into a database table.
The following is the syntax for the SQL Update command. The words in capitals are the keywords that must be used as is. The text strings within quote marks in the syntax of SQL Update query indicated need to be filled by actual parameter values for pinpointing the specific items to be updated.
UPDATE [table name]
SET [column name1]= ‘column value1′
WHERE [a particular column name]=’existing value of the column’
This above syntax of SQL Update specifies a specific table name on which data updates are to be made. The SET keyword lets the user specify the new values to be created in the given fields/columns of the table. The WHERE keyword specifies the existing value of a keyword so that the particular record can be pinpointed. In the absence of the WHERE keyword in the SQL UPDATE syntax, all the records will get updated. Let us follow this with an example so that the exact meaning is very apparent.
A phone book is something every one of us use. If a typical phonebook was implemented in an RDBMS a table “PhoneDirectory” could look something like the table indicated below.
A simple table like this could be updated manually. When the phone book is large, for example, the public phone book for the organization, updating will need database support. One of the most common changes that can happen is that the person may have switched over to another company. His or her work phone or home phone could change. SQL UPDATE statement provides the means to make a change to the database, specifically to a particular record in the database.
For the sake of illustrating the use of the SQL UPDATE, let us assume Robert Halden has been transferred to a different city where the ABC, Inc. has an office. In such a case both his work and home phones would change. SQL UPDATE command for making these desired changes would look like the following.
SET WorkPhonenumber=’397-478-2294′, HomePhoneNumber=’397-225-8325′
WHERE ContactName=’Robert Halden’
This SQL UPDATE statement chooses the right table in a database and substitutes the work and home phone numbers of a specific record where the contact name is Robert Halden. The update happens in just one record that is required to be updated. If some particular column value(s) for all records were to be updated, dropping the WHERE clause of the SQL UPDATE command would do the job. The SET clause will specify the column and the value to be set in the complete database.
What a database is simply a repository of data. Data are pieces of information that is important for some purpose; business or otherwise. Typically, you would need to add to the repository, pieces of data may need to be updated/ modified. When a piece of data has outlived its purpose, users would like to delete the same. A software system that lets you manage data and meet your needs as described is a Database. Examples of databases we are familiar with would be,
RDMS or relational databases are in popular use for storing such data in an enterprise. These use an organization known as tables. These tables themselves are organized in a manner familiar to all of us as rows of information that has columns to store related pieces of data for that row. Tabular organization helps searching flexibly. Relational databases allow relating multiple tables together for the data finding and manipulation purposes. This is something we do at personal levels too. Our telephone book is a prime example of this organization. A name with first name and second name, telephone number, possibly the address goes into such a phone book. Often important dates like birthday, wedding anniversary and other information are included. One such entry will be a record in a particular database row. Each of the items will go into a column that is common to all the records. Some well-known and popular databases are Oracle, SQL Server and MySQL.
Sometimes the database may be organized in a distributed manner. The data are placed at different physical locations and parts of the database may have copies at different spots on the network.
An associated concept to a database is a database management system. These database products let you store multiple databases and have very large capacities to do so. In a typical business, you may need to store data about customers, sales made, details of your inventory and so on. There is a need for a management process to let the diverse databases work properly. The DBMS or the database management system lets read or write access in a disciplined manner. Authorization of users is managed by the system. Analysis of usage and performance are also provided. Then, of course necessary types of reports are usually provided by these database management systems.
Database and database managers are available on the full spectrum of systems; from mainframes to personal computers and everything in between. Major difference is in the capability of the amount of data that could be handled by the different versions of each product. In all these incarnations of the database products, it is the relational database that is currently used predominantly. All the products use a form of a query language that has become an ANSI as well as ISO standard. This is known as Structured Query language or SQL. This language lets the users specify queries to find data, manipulate or update them. It has commands for changing the structure of the database too.
The Microsoft RDBMS product SQL Server is available in several editions. The most common ones are the Express, Standard and the Enterprise editions. Standard versions of each release will have more features and capabilities than the Express version. SQL Server Enterprise edition, in turn, has more capability than the standard editions of each release. Depending on the release version of the product, there may be additional versions.
For example, the 2012 release has a business intelligence edition. We shall concentrate on this latest product here, the SQL Server 2012 Enterprise version. While the Express edition is for familiarization, the SQL Server Enterprise is for serous applications like implementing high capability data centers with extensive database and business intelligence solutions.
Some of the notable features of the SQL Server Enterprise edition 2012 include the following:
The huge amounts of data that gets generated today needs to be managed and stored. One never knows what kind of insight is available from the big data collection. Besides the efficient storage and management implemented in SQL Server Enterprise edition, it ensures the ability to view the data to discern any valuable patterns. An additional tool of Power Pivot in the Power View feature of the SQL Enterprise version helps users to access and combine data from other sources to derive meaning to data visualizations being made. Support of cleansing of data helps the IT department to ensure BI solutions that are dependable. There will be no need to drill down to low-level data to ensure they are good data.
Whenever a new version of a product arrives on the scene, a question that arises without fail is whether existing users should upgrade. ROI percentage and the time it takes to recoup the investment are good metrics to help you decide. According to a Forrester study commissioned by Microsoft for an upgrade to SQL Server Enterprise 2012 has indicated that ROI percentage is 189%, and the payback time is just one year.

Microsoft released their product SQL Server 2008 r2 in 2010. As it is usual with their products, MS SQL Server 2008 R2 also has an Express edition that is available for evaluation and use in small systems. Microsoft SQL Server 2008 r2 is available in Standard and Enterprise editions. Having tried out the SQL Server 2008 r2 Express, you would eventually graduate to either the standard or the Enterprise editions depending on your actual needs. Two other special editions also were released with the MS SQL Server 2008 R2. These are the SQL Server 2008 R2 Datacenter and SQL Server 2008 R2 Parallel Data Warehouse. These two special editions were introduced to meet increasing demands for datacenters and parallel data warehouse applications (Business Intelligence applications).
As with other versions, Microsoft SQL Server 2008 R2 Express edition is supplied free by Microsoft. This facilitates your team becoming familiar with the database product, get used to developing web based and desktop applications, etc. You will need the help of Microsoft Visual Studio and Visual Web Developer Express.
Some features added over the MS SQL Server 2008 R2 include the following:
For getting started with the 2008 R2 you need to download the Express edition first. It is fairly simple to download and install. It is free to use, but you will need to get the product registered with Microsoft. Your team can start getting familiar with it right away. When the team gets into applications development activities, there is another issue you need to take into account. All such database applications need to have the database as part of the application and then the question is if you can re-distribute the database to a third party (your customer). This too is free for the Express edition, but you will have to apply and get the right approved by Microsoft.
The so-called core editions of Enterprise and Standard are the most popular ones of the SQL Server 2008 R2 product. The SQL Server 2008 R2 Standard is positioned as the database tool for data management as well as business intelligence for departments and also the small and medium business segment. This configuration is supposed to take up minimum of IT resources. Some new features in the Standard edition are:
The SQL Server 2008 R2 Enterprise is capable of delivering a data platform but provides the user a secure, highly available and scalable product. Business intelligence features are supported. Some new features in the Enterprise edition include:
The Microsoft SQL 2008 R2 also offers a free Compact edition for applications on mobile devices besides desktop and the web.
