![]() Since 2020, Flatfile has been focused on its upmarket product line, Flatfile Workspaces, used by customer success teams to assist with manual data import workflows.įlatfile’s is a powerful platform that serves multiple use cases, and excels when data import workflows are expected to be supported by a member of your onboarding team. Their first product line (Flatfile Portal v2) was an embeddable CSV importer that saved product and engineering teams the effort of building out a complex CSV import feature. ( Update 2: After updating the question to mention PDFs and what sounds like a reporting-system requirement, I think you really should be using a real database but perhaps a small and easy to use one, like firebird, or interbase.Flatfile is a data onboarding platform used by SaaS companies to configure new customer data. This is a key reason why I would recommend you start out with what might at first seem like overkill (SQLite) instead of rolling your own binary solution. Binary file formats have a lot of strikes against them, especially since it is difficult to grow and expand your binary file format over time, without breaking your ability to read old files. If you use the "FILE OF RECORD" type, you hit the 2gb limit, and there are problems with Unicode. Roll your own TurboPascal era " file of record". Probably what you are looking for, especially for append-only write as the primary operation. You mentioned originally in your question, power basic which has something called Random Access files, and then you deleted that from your question. The most flat of flat binary fixed-record-length files. There are multiple files involved, and there are indexes, so you can look up data fast without loading everything into memory. Roll your own ISAM, or VLIR, which will eventually morph over time into your own in-house DBMS. It is a very light embedded database, and is trusted by many. It is well tested, and used in lots of C/C++ and Delphi applications, and can be trusted more than anything you could roll yourself. For example, you could use SQLite and a delphi wrapper. Recommended: Something that uses SQL but isn't as large as standalone SQL database servers. Personally, I wouldn't start a new project and use anything in this category. It's just a binary key-value (hashtable) blob storage mechanism, using a well-understood binary file format. Does that make it a database, in your view? Because it's not a relational database, and doesn't do SQL. Something that isn't a full SQL database, but more of a key-value store, would technically not be a flat file, but it does provide a single "key+value" list, that is quickly searchable on a single primary key. ![]() You don't want to use a full SQL database, and you think that a plain text file is too simple. Also consider using the RTree virtual table of SQLite3, which is dedicated to speed up access to double min/max multi-dimensional data: it may speed up a lot your requests. ![]() Sometimes, using additional values (like temporary sums or means) to the data is a good idea. It's a bad idea to read all file content for every request: you should better structure your data so that a single SQL query would be able to return the expended results. Update: If you plan to use SQLite, you should first guess how the data will be stored, which indexes are to be created, and how a SQL query may speed up your requests. More than 600 pages, with details of every class method, and new enhanced general introduction. I've just updated the documentation of the framework. With full Source code, working from Delphi 6 up to XE. Reporting from code, including pdf file generation.Synopse SQLite3 Framework if you would rather use a standard SQLite engine for the storage - it comes with a full Client/Server ORM.Synopse Big Table to store huge amount of data - see in particular the TSynBigTableRecord class to store an unlimited number of records with fields, including indexes if needed - it will definitively be faster and use less disk size than any other regular SQL DB.If you don't want to reinvent the wheel, you may find all needed Open Source tools for your task from our side:
