For their Sybase SQL Server relational database engine in 1984, and later by Microsoft in Microsoft SQL Server, TDS packets can be encased in other physical transport dependent protocols, including TCP/IP, named pipes, and shared memory. Initially designed and developed by Sybase Inc. TDS is an application layer protocol, used to transfer data between a database server and a client. All operations that can be invoked on SQL Server are communicated to it via a Microsoft-defined format, called Tabular Data Stream (TDS). The data in the database are stored in primary data files with an extension. A SQL Server database can contain a maximum of 2 31 objects, and can span multiple OS-level files with a maximum file size of 2 60 bytes (1 exabyte). In addition to tables, a database can also contain other objects including views, stored procedures, indexes and constraints, along with a transaction log. It also makes server statistics available as virtual tables and views (called Dynamic Management Views or DMVs). The rounding of floats to integers uses either Symmetric Arithmetic Rounding or Symmetric Round Down ( fix) depending on arguments: SELECT Round(2.5, 0) gives 3.Microsoft SQL Server also allows user-defined composite types (UDTs) to be defined and used. SQL Server supports different data types, including primitive types such as Integer, Float, Decimal, Char (including character strings), Varchar (variable length character strings), binary (for unstructured blobs of data), Text (for textual data) among others. A page is the basic unit of I/O for SQL Server operations. Storage space allocated to a database is divided into sequentially numbered pages, each 8 KB in size. Log files are identified with the. Ndf extension, are used to allow the data of a single database to be spread across more than one file, and optionally across more than one file system.
