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

Product development is becoming increasingly complex. The pace of technological change grows daily, leaving little time to accumulate expertise before development of a new product begins. Acquiring enough experience to be able to predict the risk and develop the courses of action during the development is difficult and often happens during the course of the true developmental phases of the new product development. This situation creates a need for tapping into the skills and abilities of all the participants in the development effort and relying less on heroic efforts to save the day and carry the project and product to a successful conclusion. Even when we have product development heroes and they carry the day, the loss of these individuals to the organization will be detrimental to the organization and represents a human resources risk. The recovery period can be prolonged for organizations with poor team practices and those that favor heroic actions. We are presenting a modified version of the agile software development tool scrum as an alternative to traditional program management and as a tool for standard line management. Both of us have experience in deploying and implementing the tool. We understand the pitfalls of this method, which we will elucidate during the course of our discussion. We are not saying that we believe the waterfall approach should be condemned to obscurity or that we are calling for the death of this development model. In fact, we know of few organizations that take the waterfall method as it is often portrayed in books; that is, taking it to be a rigid and one-way pass through the development process. In fact, there are some similarities between the methods, although scrum approach throughput is quicker and keeps people focused on what is deemed important by the project managers. Basically scrum is to the waterfall approach what lean manufacturing (especially one-piece flow) is to batch-mode manufacturing. Additionally, the team aspects of the method—moving toward self-directed work teams—means the actions of the team must be successful and are largely in the hands of the team itself. The concept of a self-directed work team also suggests we must have a motivated and skilled team capable of achieving project goals. It is unwise to condemn conventional tactics across the board, when frequently the conventional tactics are not executed well. Poor execution does not improve the probability of
