SQL Server Database Engine includes the Database Engine, the core service for storing, processing, and securing data, replication, full-text search, tools for managing relational and XML data, in database analytics integration, and PolyBase integration for access to Hadoop and other heterogeneous data sources, and the Data Quality Services DQS server.

Analysis Services includes the tools for creating and managing online analytical processing OLAP and data mining applications. Reporting Services includes server and client components for creating, managing, and deploying tabular, matrix, graphical, and free-form reports. Reporting Services is also an extensible platform that you can use to develop report applications. Integration Services is a set of graphical tools and programmable objects for moving, copying, and transforming data.

MDS can be configured to manage any domain products, customers, accounts and includes hierarchies, granular security, transactions, data versioning, and business rules, as well as an Add-in for Excel that can be used to manage data. R Services In-Database supports distributed, scalable R solutions on multiple platforms and using multiple enterprise data sources, including Linux, Hadoop, and Teradata. Database Engine Tuning Advisor helps create optimal sets of indexes, indexed views, and partitions.

Provides a highly simple and intuitive graphical user interface to connect to the DQS server, and perform data cleansing operations. It also allows you to centrally monitor various activities performed during the data cleansing operation.

Formerly called Business Intelligence Development Studio. User-specified fillfactor values can be from 1 through If a value is not specified, the default is 0. Fill factor values 0 and are the same in all respects. A column set is an untyped XML representation that combines all of the sparse columns of a table into a structured output. For more information about column sets, see Use Column Sets. Specifies the names of the columns that the system will use to record the period for which a record is valid.

For more information, see Temporal Tables. For a memory-optimized, delay specifies the minimum number of minutes a row must remain in the table, unchanged, before it is eligible for compression into the columnstore index. SQL Server selects specific rows to compress according to their last update time. For a disk-based table, delay specifies the minimum number of minutes a delta rowgroup in the CLOSED state must remain in the delta rowgroup before SQL Server can compress it into the compressed rowgroup.

The options are as follows:. Applies only to columnstore indexes, including both nonclustered columnstore and clustered columnstore indexes. This is the typical choice. This can be used for archival, or for other situations that require a smaller storage size and can afford more time for storage and retrieval. For more information, see Data Compression.

Specifies the XML compression option for any xml data type columns in the table. The default is OFF. The default is 0. ON A warning message will occur when duplicate key values are inserted into a unique index.

Only the rows violating the uniqueness constraint will fail. OFF An error message will occur when duplicate key values are inserted into a unique index. When OFF, automatic statistics updating are enabled. The Database Engine determines when row locks are used.

When OFF, row locks are not used. The default is ON. The Database Engine determines when page locks are used. When OFF, page locks are not used. Specifies whether or not to optimize for last-page insert contention. Specifies the windows-compatible FileTable directory name. This name should be unique among all the FileTable directory names in the database. Uniqueness comparison is case-insensitive, regardless of collation settings.

If this value is not specified, the name of the filetable is used. Specifies the name of the collation to be applied to the Name column in the FileTable. The collation must be case-insensitive to comply with Windows operating system file naming semantics. If this value is not specified, the database default collation is used.

This collation must be case-insensitive. Specifies the name to be used for the primary key constraint that is automatically created on the FileTable. If this value is not specified, the system generates a name for the constraint. Enables system versioning of the table if the datatype, nullability constraint, and primary key constraint requirements are met. The system will record the history of each record in the system-versioned table in a separate history table. If the name of a history table is specified during history table creation, you must specify the schema and table name.

If the history table does not exists, the system generates a new history table matching the schema of the current table in the same filegroup as the current table, creating a link between the two tables and enables the system to record the history of each record in the current table in the history table. By default, the history table is PAGE compressed.

If current table is partitioned, the history table is created on default file group because partitioning configuration is not replicated automatically from the current table to the history table.

When creating a link to an existing history table, you can choose to perform a data consistency check. This data consistency check ensures that existing records do not overlap.

Performing the data consistency check is the default. Using existing history tables with ledger tables is not allowed. Creates the new table with Stretch Database enabled or disabled. For more info, see Stretch Database. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. For more info about enabling Stretch for a table, see Enable Stretch Database for a table.

Before you enable Stretch for a table, you have to enable Stretch on the server and on the database. For more info, see Enable Stretch Database for a database. Optionally specifies a filter predicate to select rows to migrate from a table that contains both historical and current data.

The predicate must call a deterministic inline table-valued function. For more info, see Enable Stretch Database for a table and Select rows to migrate by using a filter function. If you provide a filter predicate that performs poorly, data migration also performs poorly.

For more info, see Disable Stretch Database and bring back remote data. For more info, see Pause and resume data migration -Stretch Database. Enables retention policy based cleanup of old or aged data from tables within a database. For more information see Enable and Disable Data Retention.

The following parameters must be specified for data retention to be enabled. The following data types are allowed for the filter column.

The retention period is specified as a combination of an positive integer value and the date part unit. The value ON indicates that the table is memory optimized. Memory-optimized tables are part of the In-Memory OLTP feature, which is used to optimize the performance of transaction processing. For more in-depth information about memory-optimized tables see Memory-Optimized Tables. The table schema is persisted but any data updates are not persisted upon a restart or failover of the database.

Indicates the number of buckets that should be created in the hash index. For more information about bucket counts, see Indexes for Memory-Optimized Tables. For details about adding and removing indexes on memory-optimized tables, see Altering Memory-Optimized Tables. Otherwise, the system creates an updatable ledger table.

An updatable ledger table must also be a system-versioned table. An append-only ledger table must contain exactly one column defined with each of the following arguments:. If there is a name conflict with an already defined column, the system will raise an error. It also delivers peace of mind with the fewest security vulnerabilities of any enterprise database six years in a row.
