You will learn how to use SQL Server 2014 Management Studio and the advanced Transact-SQL queries to retrieve data from the SQL Server database. You will also learn how to add, modify, and delete data stored within a database. You will use Transact-SQL statements to create and manage advanced database objects that include scalar and table-valued functions, views, stored procedures, and triggers. Finally, you will learn about how the SQL Server 2014 relation engine works, how indexes and statistics improve query performance, and the new SQL Server 2014 in-memory technologies. Enterprise edition unlike the Standard one supports a wide array of data warehouse features, adds support for more users, databases, and transactions. It also includes several other advanced features such as data compression, enhanced security, and support for large database sizes.
The first version was released back in 1989, and since then several other versions have broken into the market. Each version comes with its defining attributes and serves different audiences and workloads.
Each page is written along with its checksum when it is written. When reading the page back, its checksum is computed again and matched with the stored version to ensure the page has not been damaged or tampered with in the meantime. The most well known sql server 2014 new features for dba differences between SQL Express and other editions are thecaps on database size and lack of a SQL Agent feature. There are many other differences though, some of which can be extremely important for some application and architecture requirements.
The significant concepts of graph databases are edges and nodes. The relationship between the two allows entities to be linked together directly and can be retrieved in one operation. It allows you to resume, pause and even rebuild your indexes as you please. Consequently, you don’t have to rebuild an index that you had already built halfway. This capability is based on Artificial Intelligence which tunes the database accordingly, checking and fixing issues. This allows you to query data from a distinct focal point. As such, you can query data stored in Oracle, Teradata, HDFS or any other sources.
Using the Full-Text Indexing Service, you can create more efficient queries than those with the LIKE operator. Microsoft’s Business Intelligence Development Studio is used for developing data analysis and business intelligence solutions. It is based on the Visual Studio development environment but has different extensions and project types for the database server. The SQL Server operating system, or SQLOS, lies at the heart of all database functionality. It manages memory and I/O resources, jobs and processes that access databases, and the TDS protocol that uses streams to transfer data from server to client.
This means that you can move your storage into the cloud while keeping all the transaction processing on your local server. Furthermore you can enableTransparent Data Encryption on databases while keeping the encryption key on the local server for added security. The new Memory-Optimized table feature of SQL Server 2014 allows us to safely create tables in memory for improved performance. A second copy of the table exists on disk and is updated shortly after transactions are updated. These tables are also versioned so that concurrent reads and writes are supported with reduced locking. A non-durable, memory only table is also supported – but in case of a crash all data in these tables will be lost. This feature can improve performance substantially but there is a small window where a crash may cause data loss.
Network interfaces handle communication between database servers and clients. Developer edition is designed for developers who need to create application products that will run on top of SQL Server.
It provides a scripting interface to write scripts to create or maintain databases. The GUI tool for configuring, managing, and administering any SQL infrastructure. The tool presents a graphic interface for working with SQL Server database servers and includes a bunch of script editors and graphical tools for working with objects on the server. At the user level of SQL Server, DBAs and developers write T-SQL statements to develop and change database structures, manage data, implement security protections, back up databases, etc. Web edition presents a low-cost option and differs from the Standard edition primarily in terms of maximum memory for the buffer pool and maximum compute capacity. This metadata system objects are a cumulative collection of data structures of SQL servers. When DMVs are used, they define the baseline or pressure points of various metrics that determine the performance of the database system.
Purpose of this concept was high availability of the database and isolates some of the heavy read such as reporting from the database. In SQL Server 2012, secondary copy of your database were limited to 4 replicas, however in SQL Server 2014, it is increased to 8 secondary replicas. There are some prerequisites that need to be considered before you can use this feature. For cross-instance applications, Service Broker communicates over TCP/IP and allows the different components to be synchronized, via exchange of messages. The Service Broker, which runs as a part of the database engine, provides a reliable messaging and message queuing platform for SQL Server applications. SQL Server 2022, released in 2022, adds improved analytics, disaster recovery the “Purview” unified data governance and management service, and plumbing improvements that make the database faster and more resilient.
In AlwaysOn 2012 and 2014, you were allowed a maximum of two replicas to designate for automatic failover. AlwaysOn 2016 allows three replicas for automatic failover. You must have synchronous data replication and automatic failover set between the primary and the secondaries.
SQL Server Management Studio is a GUI tool included with SQL Server 2005 and later for configuring, managing, and administering all components within Microsoft SQL Server. The tool includes both script editors and graphical tools that work with objects and features of the server. SQL Server Management Studio replaces Enterprise Manager as the primary management interface for Microsoft SQL Server since SQL Server 2005. A version of SQL Server Management Studio is also available for SQL Server Express Edition, for which it is known as SQL Server Management Studio Express . Microsoft Visual Studio includes native support for data programming with Microsoft SQL Server.
This server is the first of its type to support pause and resume functionality for index maintenance operations. While rebuilding indexes is quite a daunting engagement, most database management systems do not allow for offline maintenance. Buffer Pool Extension is a great feature of SQL Server 2014, it enables buffer pool to extend buffer pool size between RAM and SSD . Just to give you a little background about buffer pool if you already don’t know it, buffer pool is primary memory allocation source of SQL Server.
The query is expressed using a variant of SQL called T-SQL, a dialect Microsoft SQL Server shares with Sybase SQL Server due to its legacy. The query declaratively specifies what is to be retrieved. It is processed by the query processor, which figures out the sequence of steps that will be necessary to retrieve the requested data. The sequence of actions necessary to execute a query is called a query plan. In such case, SQL Server chooses the plan that is expected to yield the results in the shortest possible time. This is called query optimization and is performed by the query processor itself.
