Basic concepts The official document in TensorFlow describes the dataset data object in this way: A dataset can be used to represent a collection of input pipeline elements (a nested structure of tensor) and a "logical plan" for translating these elements into action. In a dataset, an element can be a vector, tuple, or dictionary form.In addition, the

Chapter 6 What is a datasetDelphi 4 has four types of Standard dataset components: tTable, tquery, tstoredproc, and tclientdataset. These dataset components are inherited from a common basic class tdataset, where only tclientdataset is inherited directly from tdataset, while tTable, tquery, and tstoredproc are directly inherited by tdbdataset, the upper level of tdbdataset is tbdedataset, and that of tbdeda

The dataset stores data in the disconnected cache. The structure of a dataset is similar to that of a relational database. It exposes hierarchical object models of tables, rows, and columns. In addition, it contains the constraints and relationships defined for the dataset.Source: http://msdn.microsoft.com/library/chs/default.asp?

Difference between DataRead and DataSet: datareaddatasetDifference between DataRead and DataSet Dataset indicates a dataset, which is cached in memory. Can contain multiple tablesDatSet is non-connection-oriented when connecting to the database. Read all tables to the SQL Buffer Pool and disconnect from the database. D

Dataset is a method used to connect to SQL. It means to store database copies in an application. When an application starts running, it saves database-related data to dataset. Datatable indicates a table with data in memory. You can use view to obtain a custom view of a table that may include a filtering view or a cursor position. The datareader object is the simplest way to read the database. It can only r
