This document records the course design work I completed during my freshman year. The main objective of this course design is to develop a chat software product that has similar functions to QQ. The system adopts the C/S (Client/Server) architecture mode. Under normal circumstances, the client end of the system runs the application program that provides the user interaction interface, while the server end runs the service program that is responsible for processing business logic and data. When the user needs to perform a certain operation, the application program on the client end will submit a corresponding app

Product Description Universal Data Access Components (UniDAC) is a library of components that provides direct access to most popular database servers from Delphi, Delphi for .NET and, C++Builder. UniDAC can work with such servers as Oracle, Microsoft SQL Server, MySQL, Interbase, Firebird. The UniDAC library is designed to help programmers develop faster and cleaner cross-database applications. UniDAC is a complete replacement for such standard universal technology as dbExpress. UniDAC is a handy in use and efficient data access solution bringing into play many features specific to each server. Requirements UniDAC is a product joining functionality of such data access solutions as ODAC, SDAC, MyDAC, and IBDAC. Requirements of UniDAC depend only on used providers. Detailed requirements for each provider can be found in the Requirements topic in the UniDAC Help documentation. Installation Compiled versions of UniDAC are installed automatically by the UniDAC Installer for all supported IDEs. Versions of UniDAC with Source Code must be installed manually. For more information, see the Installation topic of the UniDAC Help documentation. It is important to know that UniDAC, ODAC, SDAC, MyDAC, and IBDAC use the common base packages, so product compatibility is provided for the current build only. In the other words, if you upgrade one of the installed providers, it may conflict with older builds of other products. In order to continue using the products simultaneously, you should upgrade all of them at the same time. 7.1.4 29-Sep-17 InterBase data provider Bug with the "Input parameter mismatch" error for procedure is fixed Bug with transactions when working with Firebird 2.5 is fixed 7.1.3 19-Sep-17 The performance of TVirtualQuery is significantly improved Application-defined functions in TVirtualQuery are supported Application-defined collations in TVirtualQuery are supported AutoInc fields in TVirtualTable are supported Bug with assertion failure when updating a record in TVirtualQuery is fixed Bug with compatibility with TkbmMemTable in TVirtualQuery is fixed Bug with complex WHERE clauses that have several string fields in TVirtualQuery is fixed Bug with selecting from a dataset with a single record in TVirtualQuery is fixed Bug with generating SQL for batch updates is fixed Bug with the Locate method for non-Windows platforms in Lazarus is fixed Bug with the FindFirst, FindLast, FindNext, FindPrior methods in Lazarus is fixed Bug with accessing a product help from the IDE menu is fixed Bug with recreating fields when calling Open after Prepare is fixed Bug with an incorrect error message when using the Connect dialog component on mobile platforms is fixed Bug with AV failure when using calculated fields in TClientDataset is fixed Bug with a key violation error when executing batch operations is fixed Bug with Assert when calling the Locate method in the SmartFetch mode is fixed Bug with using DAC components in DataModule for Linux is fixed Cloud data providers BigCommerce provider is added Dynamics CRM provider is added FreshBooks provider is added Magento provider is added MailChimp provider is added NetSuite provider is added QuickBooks provider is added Salesforce provider is added Salesforce Marketing Cloud provider is added SugarCRM provider is added Zoho CRM provider is added Oracle data provider Oracle 12c connection modes (SYSBACKUP, SYSDG, SYSKM) in the Direct mode are supported OS authentication in the Direct mode is supported NChar literal replacement is supported CLOB parameters behavior when UnicodeEnvironment=True is improved Bug with lost chars in a parameter value when ConvertEOL=True is fixed SQLServer data provider Bug with processing varchar fields when AutoTranslate is True in the Direct mode is fixed Bug with processing a field with alias for query with the JOIN statement is fixed Bug with date and time fractional seconds precision when DescribeParams = True is fixed MySQL data provider Azure Database for MySQL is supported JSON data type is supported InterBase data provider Support for Firebird on Android platform is added Support for Firebird 3 packages is added Aliases handling in the RETURNING clause is supported The WireCompression connection parameter for Firebird 3 is supported Bug with using BLOB data type in batch operations is fixed Bug with the OnBackupProgress event handler in TUniDADump is fixed Bug with using batch parameters of the Bytes type is fixed Bug with closing a connection that has an active transaction for Firebird 3 is fixed Bug with recreating a connection on Linux and mobile platforms is fixed PostgreSQL data provider SSPI authentication is supported Processing GUID data type for the TGuidField class is improved SQLite data provider Now the Direct mode is based on the SQLite engine version 3.20.0 Custom SQL aggregate functions are supported Bug with opening an existing database on iOS 64 is fixed Bug with detecting field types is fixed Bug with international symbols in non-Unicode Delphi versions is fixed Bug with low performance of the LoadFromDataSet method of the Loader component is fixed Bug with index backup using the Dump component when the TableNames property is set is fixed DBF data provider The CodePage specific options are added The ConnectMode specific options are added Bug with using CDX indexes is fixed DB2 data provider The DECFLOAT data type is supported 7.0.2 15-May-17 Bug with using TVirtualQuery with TVirtualTable is fixed Bug with processing NULL values in the Loader component is fixed Bug with executing a query after executing a batch command is fixed Bug with executing a batch operation inside an explicitly started transaction is fixed Bug with using the AsGuid property is fixed Oracle data provider Bug with authentication in the Direct mode is fixed MySQL data provider Bug with processing DATETIME fields is fixed SQLServer data provider Bug with the "Invalid column name" error when editing a query with the JOIN statement is fixed InterBase data provider Bug with memory leak when using the SQLMonitor component is fixed PostgreSQL data provider Bug with AV failure after executing the Ping method is fixed SQLite data provider Bug with creating a database in the Direct Mode on Android is fixed
